Add water to the fill layer by passing the water tanker over the fill layer. The water tanker should pass over the layer twice. A time gap of approximately two hours is allowed for the water to soak into the fill material. The layer is now mixed with the grader until a uniform blend of moist material is achieved. Additional water is added by passing the water tanker over the layer in a uniform sequence. A time period of approximately one-hour is allowed for this water to soak into the fill layer. The fill layer is mixed again with the grader leaving the fill level to the correct grade. Vibrating rollers shall now compact the fill layer in a logical sequence that compacts the fill layer uniformly. Testing of the layer shall be conducted according to specification requirements.

Responsibilities The CM shall plan and resource the concrete repair activities, to ensure that they are implemented according to this method statement. The Construction Foreman shall monitor the concrete repair activities, directing the workforce as necessary.
Safety Prior to the commencement of any activities, the labour force shall receive a tool box talk on the project site safety requirements. Any process that is adopted that may have a particular safety risk, shall be assessed and addressed as required.
Method Upon removal of the formwork, the concrete surface shall be inspected by the Site engineer & foreman to check surface defects. Where no surface imperfections have occurred, the concrete surface shall be cured according to the relevant procedure. Minor defects as described in A – D below shall be repaired as soon as practical. More significant defects as described in E – H shall be subject to joint inspection / agreement between Civil Contractor, EPC Contractor and Company. A. Pin holes / blow holes Where small defects to the concrete surface has occurred such as pin holes or holes smaller than 3mm in diameter or depth, the surface shall be repaired using Nitomortar FC with an approved bonding agent. This surface repair shall be conducted as soon as the formwork is removed whilst the concrete is still green. The repair shall then be cured in accordance with manufacturer’s instructions or agreed procedures using water or curing agent as appropriate. B. Sand runs / scouring Water movement inside the shutter can result in a streaky appearance giving loose sandy finish. Where this occurs, any loose material shall be removed by stiff brushing and then repaired as described in A above. C. Plastic shrinkage cracks Cracking caused by plastic shrinkage due to inadequate curing and protection of horizontal surfaces usually results in a series of diagonal cracks. These should be repaired by brushing dry cement powder directly into the cracks while the concrete is less than 3 days old and covering with damp hessian. Statements were written by Professional Eng Suraj Singh Project Manager as well as Senior Project Engineer.

D. Minor misalignments (Typically Less than 2cm) Misalignments due to shutter movements etc, should be ground back to provide a smooth transition between areas. Where occurring at joints between panels, the ground profile length should be 2-3 times the size of the maximum misalignment. Following grinding, the surface should be reinstated as in A above. Care should be taken to ensure that concrete cover is maintained per specifications at all times. E. Honey combing / segregation / minor voids The repair shall be conducted as soon as the formwork is removed and the repair method agreed with EPC Contractor / Engineer. It shall require chipping the repair area free of laitance and exposing any voids. The repair area shall then be soaked, an approved bonding agent applied followed by working on with an approved mortar such as Master Flow 544 before the area dries out.. The materials shall be mixed using the bonding agent and not water. The mixed material shall be trowelled firmly into the repair area. Incase, the depth of the repair exceed 15mm, the repair shall be conducted in two layers providing a scratch coat on the first layer. The repair shall then be cured in accordance with the agreed procedure using water or curing compound as appropriate. F. Major voids (Typically Deeper than 5cm) This repair shall consist of chipping the affected area to remove any laitance and voids. Where reinforcement is exposed in a void, the surrounding concrete shall be chipped away to provide adequate space to place fresh concrete around the reinforcement including removal of all soft concrete. (Note- a distance of one and a half times the stone size must be allowed around all exposed reinforcement). Formwork shall be provided to retain the fresh concrete. The chipped area shall be soaked in and primed with a bonding agent. The bonding agent shall not be allowed to dry. Fresh concrete of the same grade as the surrounding concrete shall be used to fill in the void. The repair shall be water cured along with the parent concrete. The surface finishes to the repair shall be as the same standard as the surrounding concrete. G. Plastic settlement cracks Cracking caused by settlement of concrete usually in deep lifts or at changes in section can result in a series of cracks which mirror the reinforcement pattern in horizontal surfaces or appear to arch on vertical surfaces. Any such cracks should be chased out to a depth of 1015mm and filled with an epoxy mortar such as Nitomortar FC as in A above. H. Pourous / spongy surface Where inadequate vibration and poor finishing techniques have caused excessive bleeding, horizontal surfaces can appear spongy and pourous. In this case all affected surfaces should be ground back to good concrete usually only 2-3mm below the surface. The surface should then be reinstated using Nitomortar as in A above. This type of defect often occurs with plastic settlement cracks which should be treated as In G above.

The code provides that notwithstanding the satisfactory completion of the test, any evidence of seepage of the liquid to the outside faces of the liquid retaining walls should be assessed against the requirement of the specification. Any necessary remedial treatment of the concrete, cracks or joints should, where practicable, be carried out from the liquid face. When a remedial lining is applied to inhibit leakage at a crack, it should have adequate flexibility and have no reaction with the stored liquid. Should the structure not satisfy the 7 days test then after the completion of the remedial work, it should be refilled and if necessary, left for a further stabilising period followed by a further test of 7 days’ duration should then be undertaken in accordance with this clause.

Preparation of backgrounds to be plastered or rendered All surfaces to be plastered and rendered shall be thoroughly cleaned of all dust and loose particles. Concrete surfaces shall be scabbled by mechanical means to remove all laitance exposing the aggregates to 3 mm depth Civil Contractor / EPC Contractor inspections shall be conducted for the approval of the prepared surfaces. A slurry coat consisting of 400 kg Cement (white) to 1 cum of sand (No. 1 White Silica) as specified shall be applied on the surface by trowel and 1-day allowance given for the succeeding coat to commence with. Block work surfaces shall have the joints raked out as specified (Ref) during construction. Junctions of different background and the chases for the electrical conduits as well as other service pipes shall be treated by fixing 200mm wide metal lath. Plastering shall not commence until all the mechanical and electrical services, conduits, pipes and Ist stage fixtures have been installed and approved. Where a rendering or plaster is to be continuous across backgrounds of different types, a strip of metal lath minimum 300 mm wide with an isolating membrane of polythene sheet or building paper behind, shall be fixed across the junction. Where small widths of one material less than 300 mm wide are involved e.g. a concrete column, beam or slab dividing block panels, the width shall be bridged completely for a distance of 150 mm on both sides. The metal lath shall be stretched out and fixed along each edge at 100 mm centres using stainless steel fasteners such as washers and shot fired pins, nails or screws and lapped joints tied with galvanized wire, the screws fixed into plugs in predrilled holes if so required. Metal lath shall not be provided where drawing shows a groove in the rendering or the plaster.

The whole of the batch shall be used within an hour of being mixed Application of the various plaster or render coats The work shall not start until the background has been prepared and all the services have been finished according to requirement and the relevant specifications as described earlier. Slurry coat shall be trowel applied allowing at least one day to start the succeeding coat Two render coat applications shall be carried out. Before applying any coat, the background or the preceding coat shall be brushed down to remove any loose particles and dampened sufficiently to ensure uniform absorption. First coat shall be trowel applied and scored to form a key for the second coat allowing at least one day before the start of the next coat. The undercoat shall be applied either by laying on with or throwing from a trowel or float, as uniformly thick as possible and not less than 8 mm or more than 13 mm thick in any part. The undercoat shall be left rough and open by the edge of the trowel after it has been long enough to set firm, be combed with evenly spaced wavy horizontal lines approximately 20 mm apart and 5 mm deep (less in case of first coat on metal lathing). The surface shall not be scratched, however, when it is to receive a Tyrolean finish. First undercoat applied to metal lathing shall be well worked into the lath to ensure that the material is completely embedded. The finishing coat shall be steel trowel applied The finishing coat shall not be less than 5 mm or more than 10 mm thick and shall be laid on with a trowel and finished with a steel float, taking care not to over work the surface. All coats shall be applied with firm pressure to exclude air and to ensure a good bond. Plaster shall be rodded and straightened to uniform surfaces in true planes. Laps of one coat shall not occur over laps of preceding coat. Each coat shall finish free from cracks, checks or other structural defects. Finish surfaces shall be flush with grounds / stop beads, corner beads, outlet boxes and similar details, free from trowel marks, other blemishes displaying straight arises and true angles. All coats shall be prevented from drying out too quickly and the work be carried out in shade during hot period. All renderings shall be protected by properly constructed hessian or similar screen during hot period Each coat shall be kept damp by means of a fog spray of water for a minimum of 3 days to allow before a subsequent coat is applied or in the case of a finish coat, before the protective screens are removed The surface of the finish coat shall be smooth, true and free from waviness, irregularities or blemishes with straight, level or plumb angles. External angles shall be pencil rounded Care shall be taken when rendering up to beads or stops to avoid excessive polishing at the arris and damage to the galvanizing.

During mixing and application of master seal 550, personnel protective equipment shall be used i.e. overalls, goggles, gloves (to avoid material contact to eyes, mouth and skin) Material storage / disposal of used containers / waste material Materials shall be stored out of direct sunlight clear of ground and protected from rainfall. Used containers shall be collected and disposed off as per project requirements.
Materials Coating, Masterseal 550 Master seal 550 is a two component acrylic modified cementitious coating that requires only site mixing to form an ideal product to waterproof and resurface concrete, masonry and most other construction materials. Simply applied by stiff brush, roller or trowel it forms a waterproof, flexible coating providing an effective barrier to waterborne salts and atmospheric gases.
Method The method involves the following sequences in general. Surface preparation Mixing Application Details All grease, oil, dust, residual curing compound, mould release agent or other contaminants, which could impair adhesion, shall be removed from the surface by degreasing and washing. The whole surface to be coated shall be cleaned using water jetting and visually inspected to ensure that the roughness does not exceed grade 80 sandpaper. All the holes, voids, depressions, spalls etc., shall be filled with Masterseal 550 mixed to a trowel consistency ,scraped lightly into the surface, allowed to dry and later roughened by hand wire brush on the small areas and gently water jetted on the larger areas. The filled areas shall be visually inspected to ensure that the correct mechanical key is achieved. Mixing Master seal is supplied in the pre measured units and shall be mixed on site using clean containers. The powder shall be slowly added to the liquid component and agitated / mixed for 2 minutes by using a slow speed hand power drill fitted with a suitable paddle attachment, until a homogeneous lump free consistency is obtained. The mix quantity shall be such that it could be consumed in one hour during application without allowing any retempering with water. Application Coverage 1.8 Kg / sqm at 1 mm thickness The coating shall be 1 mm thick applied in one coat In hot weather the surface to be coated shall be shaded from direct sunlight. The areas to be coated shall be saturated with fresh and clean water. The prepared and the saturated surface shall be inspected by Civil Contractor QC followed by EPC Contractor approval The mixed material shall be applied while the surface is visibly damp without standing water using short stiff brush or roller.

The water logged area shall not be allowed for the workers in general to acceed crossing the existing fence except, if so required , for the purpose of laying out hoses over used plies to be routed in to reach the proposed sumps for the pumped water disposal.
METHOD Ref Attached Drawing and Sketches The North South excavation has already been carried out to the intersection of the proposed line and the Corniche Road as indicated by point at ‘S’ On the proposed route of the lines i.e on the North of the road exist various services at a distance 4 m to 8 m at a depth of 2 to 3 m from the existing road level running along eitherside of the intersection i.e East and West as shown on the attached sketch as locations marked A to H for the exposed inspection pits The existing uneven ground level on the proposed area is 1.8 m average lower than the road level and the water is available at 2 m from the road level but fluctuates rapidly depending on the tides. The GRE pipe 2200 mm dia pair shall be laid at a bedding of not less than 4000 mm to 4500 mm from the road surface .Since the drawing shows the natural ground level 3.4 m , a 2.4 m depth is required to be excavated , while water level is shown at 2.15m level, water has to be bailed out upto 0-0 level requiring a 2m massive dewatering along the entire route commencing from the intersection at point ‘S‘ to the terminal point at ‘T’. The existing services shall be protected by the necessary measures according to the statutory regulations and the specifications prior to the excavation commencement for which an inquiry be conducted with the relevant Statutory Organizations / Client Since this massive earth work is to be carried out in full to cover a length of 1200 m or more , dewatering shall be carried out accordingly by the standard Well Point System to be installed on both sides of the proposed route at a depth of minimum 3 m from the existing ground levels at the locations shown on the sketch / drawing and disposed off through the hoses into the proposed sumps to be located at varying distances from 100 to 200 m off Statements were written by Professional Eng Suraj Singh Project Manager as well as Senior Project Engineer.

There shall be strict control of surface cleanliness between primer and epoxy coating / and between coats of the same application. Vacuum removal of dust and sand shall be employed and contamination removed. Where dirt or dust has been trapped in the painted surface, it shall be removed with suitable abrasive paper. The surface being painted shall be free of visible moisture throughout these operations The paint shall be applied only to the clean & dry primed or previously coated surfaces. Any thick runs or collections of paint shall be removed before these harden Each coat shall be distinctly different in colour from the primer or previous coat. The colour of the final coat shall be as approved. Each coat shall be seen to have completely covered the proceeding without ‘ misses’ or pinholes or any areas ‘visibly low’ in thickness. A high voltage pinhole detector shall also be used to determine the integrity of the coats “The manufacturer of the coating shall stipulate primer and epoxy recoat interval for all curing temperatures likely to be encountered and these be adopted with a maximum tolerance of +4 hours”. Where this is exceeded, the surfaces to be recoated shall first be suitably abraded to remove gloss and provide a key Wet thickness gauges shall be used by the coating operators continually to check that sufficient paint is being applied to achieve the desired dry film thickness EPOXY COATING FOR CONCRETE AND RENDERED SURFACES No priming shall commence until the moisture content of the cementitious surface is less than 5% measured by Wetcheck Moisture meter or other instrument Similarly moisture measurements over the primer or any epoxy intercoat shall not exceed 1 % on the concrete scale of the instrument when the probe tips are held against such painted surfaces just prior to recoating The priming shall be applied by suitable Nylon bristle brush or spray over the whole area to be coated at such thickness that it may then be squeezed into the pores of the concrete. Any excess shall be removed by the most suitable means before application of the high build epoxy The total DFT of the paint layer shall have a minimum specified value Whenever the paint inspection gauge has been used and wherever the coating has been otherwise damaged, the surfaces shall be abraded 50 mm around and the area touched in with not less than 2 # thick applications to restore the coating integrity to the specified thickness. Adhesion tests shall be carried out on the cured coating surface using the test equipment supplied in accordance with the best practice. The resulting test specimens shall show no indication of poor adhesion to the substrate, residual laitance or intercoat adhesion weakness. The following instrument shall be used 1 Adhesion Tester 0 to 35 kg / cm2 1 DC high voltage holiday detector # 105 One paint inspection gauge PIG 1 wet check moisture meter

This repair should be adopted where the existing screed has completely disbonded and broken up, leaving loose isolated sections of screed. Repair Type B – Repair with Epoxy Mortar This repair should be adopted where there are significant isolated cracks in the screed. It is not intended to repair minor hairline cracks by this method, or construction joints between adjacent panels of screed, unless they have become otherwise damaged. Repair Type C – Repair with Resin Injection This repair should be adopted where the screed appears to be disbonded and cracked or lifting but is otherwise intact. This may be carried out in conjunction with repair Type B above. It is not necessary to use resin injection on hollow sounding areas where there is no other sign of failure. Repair Type D – Surface Epoxy Coating This repair shall be applied as a final protective coating to all repaired areas. As well as sealing any un-repaired hairline cracks, this shall also ensure an overall uniform appearance of the repaired areas. 3.

Materials Ceramic floor tiles 300 x 300 x 10mm, For General Area ‘RAK GP 21 G’ and for wet areas Johnson ‘Athena’
Cementitious adhesive- Nitotile GP Joint filling grout – Approved proprietary material with matching shade.
Method (Laying ceramic floor tiles by SEMI DRY method) The areas of concrete sub strata to be tiled shall be brush cleaned and dampened until absorption ceases followed by the finished floor level establishment by means of dots and rules. The total thickness of the ceramic tile flooring is 100 mm which includes 90 mm bedding screed (1 cement: 4 mortar sand) to be mixed by weight and 10 mm thick ceramic tiles, shall be applied as described below. The mortar for bedding the tiles shall be 1 part cement to 4 parts sand by weight, mixed semi dry by a mechanical mixer with only sufficient water added to give a crumbly consistency which retains its shape when squeezed by hand permitting no fluidity The mix shall be placed to a thickness approximately 10 mm greater than that actually required for the bed, thoroughly compacted by tamping and drawing off to the required level with a screed board and given a smooth trowel finish. Civil Contractor QC visual inspection shall be conducted to ascertain proper compaction and levels. The surface of the screed shall be cleaned by brush prior to the application of the adhesive. The adhesive shall be mixed with water using a slow speed drill to the water adhesive ratio per manufacturer’s data sheet. Adhesive Nitotile GP mix shall be applied in uniform thickness of 2 to 3 mm over the surface of the cement sand screed bedding and then combed horizontally. Tiles shall then be laid on the adhesive layer with a twisting motion ensuring good contact between the tile and the adhesive bed. For this purpose the adhesive manufacturer’s instruction shall be adhered to. The tiles shall be correctly positioned in both directions the time these are placed forming joints using a proprietary tile spacer ( 1.5 mm for wall tiles and 3 mm for floor tiles) The tiles shall neatly and accurately be cut to a close fit where necessary at abutments, around outlets, pipes and the like. Civil Contractor QC Inspection shall be conducted for the correct formation of joint alignment and the level profile The tiles shall be laid level or to 1- % falls in ‘wet’ areas as may be required. Localised variations in level for a nominally flat floor shall be a maximum of +- 2-mm under a 3-meter straight edge.

Responsibilities The Construction Superintendent shall ensure that the concrete Foreman implements this procedure. The Concrete Foreman shall ensure that the concrete crew is fully aware of this procedure and the correct methods of working.
Safety The Safety Officer shall monitor the concrete activities, advising and implementing all safety procedures.
Method The structure that is to be concreted, shall be inspected and approved as correct, by both Civil Contractor and EPC Contractor. The permission to place concrete shall be authorized by EPC Contractor The concrete Foreman shall ensure that he has adequate equipment resources (vibrating pokers, compressors, hoses, steelfixer, carpenter, water etc), at the location of concrete placement. When the site laboratory concrete technician, has approved the concrete delivery, the concrete placement activity can commence. Refer to Method statement, Testing of Fresh Concrete. The concrete shall be discharged by one of two methods. For pours greater than two cubic meters in volume, the concrete shall be discharged through a concrete pump. For pours less than two cubic meters, the concrete can be discharged direct from the truck mixer. Regardless of the method of discharge, no concrete shall be dropped from a height greater than two meters, or in a manner that shall cause the segregation of the aggregates. Immediately prior to placement activities commencing, the reinforcement within the concrete pour, shall be sprayed with clean water. The placement of the fresh concrete within the shutters, shall be in a logical sequence. Concrete shall be placed at locations that do not exceed 1.5 meters from the final location of the concrete. The maximum concrete layer thickness of 450 mm shall be observed. The fresh concrete shall be compacted with pokers of sufficient size and number. Consolidation of the fresh concrete, shall commence when the placement of the concrete is adequate, so that uncontrolled segregation does not occur. Concrete shall be placed in a sequence that ensures that cold joints are eliminated. Each subsequent layer of concrete shall be adequately compacted into the concrete layer below. Where encast plates, holding down bolts, or any other critical embedded item is included within the pour, the surveyor shall check the location and elevation of that item, when concrete placement has been completed. Immediately the concrete finishing has been completed, the concrete shall be covered with white polythene sheeting, ensuring that the edges are sealed to prevent the circulation of air. Upon adequate setting of the concrete, the white polythene sheeting shall be removed. Hessian which has been soaked in water, shall be placed over the set concrete. The white polythene sheeting shall be replaced and sealed at the edges. The hessian shall be kept moist for a period of 14 days.

Method Pretesting Preparation It is deemed that the line shall have been kept clean during storage and construction by keeping the open ends capped, that the hydrotest package checklist points have been verified and that the line is released for hydrotest and all safety precautions are taken. It is important that the backfill and compaction of the line is done according to the installation procedures, as this shall prevent the line from moving during pressuring as well as as providing protection against impacts, shade etc. Joints shall not be backfilled; a taped off area shall be delimited around the test pump, the diameter of this area shall be 1.5 times the length of the test pressure hose between pump and blind flange; where only designated personnel shall have access. II Hydrotest Preparation 1. Any required temporary piping facilities, make up dummy spools shall be installed. 2. The main blind flange shall be fitted inter alia, with a manifold on which a pressure safety valve adjusted at 1.5 times the piping design pressure shall be connected. 3. Calibrated pressure gauge ranging from 0 to 25 bar G. shall be installed on the line. They must have valid calibration certificate. 4. The pressure hose shall be connected to the blind flange manifold through a NPT connector. 5. Venting facilities: All steel blind flanges shall be provided with bleed valves. All high points shall have a venting facility. 6. The line shall be filled with water the previous day to testing to allow for thermal stabilization over-night. 7. The filling of sloped lines shall be done from the lowest point. The filling shall be done with all vents open, vents should be closed only when clear water with no air bubbles come through the vent. Only when all vents are closed should the filling pump stopped. 8. The pressure test pump, a triplex pump model shall be started and vents reopened to ensure any remaining air in the pipe escapes. Once closed the pressure shall be taken up to the field hydrotesting pressure of 1.5 times the design pressure. During the following time periods. a. Pressure Setting Testing 5 hours for Dias up to 4” b. Main Pressure Testing The 1.5 times maximum design pressure must be held for the following duration. 3 hours for Dias up to 4” 8.1 The start time should be recorded. 8.2 30 minutes stand-up for stabilisation and monitoring shall be done for every 5 bar G.

At 1.5 operating pressure the starting time shall be logged. The test shall be monitored during this time. The pressure & temperature shall be monitored. 9. The piping systems are designed to withstand 1.5 times the design pressure of the pipes and fittings; in the unlikely event the pressure would rise above this point, the safety valve shall release water which shall be kept for re-pumping at the end of the test period. 10. After the holding time, if no pressure drop exceeding 0.3 bar G / 1000 m of line, hydrotest shall be considered as successfully passed. 11. The pressure may then be slowly released and the line gravity drained back. 12. If the pressure abnormally drops during the testing, indicating a leak, the pumping may be continued until the leak is detected. The leak shall then be repaired and after depressurising and draining the line and then procedures 2 to 11 shall be followed. 13. The hydrotest package shall be submitted in advance for COMPANY / EPC Contractor’s review. The required representatives shall complete and sign all paper work pertaining to the test. NOTES: During stages 10 to 15, utmost care shall be taken to avoid damage or shock to the lines. Personal movement shall be kept to a minimum Heavy equipment circulation shall be avoided. All Mechanical Compaction shall be stopped in the vicinity. No loose rocks or bounders shall be closer that 1 (one) meter from the trench edges. All civil works shall be stopped on the line.

Application of Water Proofing treatment shall be carried out for the wet areas. The total thickness of the ceramic tile flooring is 100 mm which includes 90 mm bedding screed (1 cement: 4 mortar sand) by weight and shall be applied as described below. The finishing layer shall be 10 mm thick and be laid as described below. The mortar for bedding the tiles shall be 1 part cement to 4 parts sand by weight, mixed semi dry by a mechanical mixer with only sufficient water added to give a crumbly consistency which retains its shape when squeezed by hand permitting no fluidity The mix shall be placed to a thickness approximately 10 mm greater than that actually required for the bed, thoroughly compacted by tamping and drawing off to the required level with a screed board. Only sufficient mortar shall be mixed and spread as can be covered with tiles before it attains its initial set. Company visual inspection shall be conducted A slurry of 1 part cement to 1 part sand by volume shall be poured over the surface of the semi – dry mix bedding and spread with a trowel until it is approximately 2 mm thick Dry tiles shall then be laid on the slurry and beaten firmly into position with a wooden beater ensuring a true surface contact between the tiles and bedding is formed. The tiles shall be correctly positioned in both directions the time these are placed forming joints using a proprietary tile spacer (1.5 mm for wall tiles and 3 mm for floor tiles) The tiles shall neatly and accurately be cut to a close fit where necessary at abutments, around outlets, pipes and the like. Company Inspection shall be conducted for the correct formation of joint alignment and the level profile The tiles shall be laid level or to 1- % falls in ‘wet’ areas as may be required. Localized variations in level for a nominally flat floor shall be a maximum of +- 2-mm under a 3-meter straight edge. Particular care shall be taken in ‘wet’ areas to prevent low spots that may promote water pooling. The tolerance in the overall level shall not be more than 10 mm from required finishes. Grouting of the joints shall be carried out within a period of not less than 24 hours after completion of laying of tiles so as to allow the grout attach itself firmly to the bedding. MOVEMENT JOINTS IN TILED FLOORS Unless otherwise indicated in the documents, a 10 mm movement joint shall be formed at the perimeter of all the tiled floors and where the tiling meets structural features such as columns, machine bases etc., Where a structural movement joint is provided in the base, a movement joint of the same width in the bedded finish shall be positioned immediately above The movement joint cavities shall extend through the combined thickness of the finish and the bedding mortar, completely filled and sealed after grouting of the normal joints takes place.
