  • Wheelbarrow 
  • Water Tanker/Water Hose 
  • Roller & brush 
  • Water Jet Blade cutting station. 
  • L Square, Trowel, Plumb bob, spirit level, Chisel, Hammer.

Procedure. 

The sequence of works outlined below is to be strictly followed to ensure the safety of all Employees during the waterproofing + Civil Works (finishes)

Production.  

The subcontractor purchasing department shall liaise with the commercial department and prepare a detailed material list for each item in accordance with the approved shop drawing. 

Supplier’s Quantity control shall take care of the quality issues if any of the material is once approved and passed by their QC team. The materials shall be stacked in pallets, protection wrapped around them awaiting delivery call of from site. When materials are delivered to site the QAQC Team and contractor/consultant representative along with the storekeeper shall inspect all goods for conformity. If a non-conformance arises swimming pool subcontractor shall issue the supplier an NCR. Material noted not in conformance with the specification to be marked and removed from the site. 

Delivery, Storage & Handling. 

All records of stock material at the storage area shall be recorded and labelled stating intended location for installation on the project.   

All materials shall be marked and monitored by Team Storekeeper.

Materials for Swimming Pool shall be stored.

Unless materials are near the intended installation area and are in the process of installation, materials shall be protected as appropriate.

Protective tapes/coverings shall be made to protect the stored materials of  unique nature and specification, materials shall be stoked in groups to increase efficiency of site deliveries.

Delivered Material should be raised for a Material inspection subject for  acceptance and approval from the consultant.

Waterproofing procedure: Mapelastic Smart A + B & Mapetex Sel  )or any other material).

Mapelastic Smart: Two-component, highly flexible cementitious mortar (with crack- bridging capacity >2 mm), to be applied by trowel or with a roller, for the waterproofing of balconies, basins, swimming pools and wet areas.

Mapetex Sel: Non-woven, macro holed polypropylene fabric for reinforcing waterproofing membranes.

Once Guniting operation was completed, site engineer will prepare the surface prior application of the waterproofing. Clean the surface and remove any un-sound or loose material. Prior to application, the substrate must be well cured, mechanically strong, and dry. Remove traces of oil, grease paint, wax, or any contamination. Inspection to be submitted once surface found to be satisfactory.

Waterproofing Membrane – Mixing 

Pour component B (Liquid) in to a suitable, clean, rust-free mixing container. 

Slowly add component A (Powder) of MAPELASTIC SMART whilst mixing using a slow speed mixing drill at 500 RPM fitted with a suitable mixing paddle. 

Mix for 2 to 3 minutes ensuring to scrape nay unmixed powder from the bottom and the sides of the container. Keep Mixing until a lump free homogenous mix is obtained.

Mapelastic smart is to be applied at the rate of 1.6kg/m2/mm per coat in two coats. 

Cut Mapetex Sel roll into appropriately sized sheets. Roll and keep aside. 

Good waterproofing detailing for corners, pipe penetrations and water traps shall be observed, ensuring to fix individual pre-cut pieces of Mapetex sel (200mm minimum width of band) as a banding system at all corners and penetrations.) 

Apply a 300mm wide band of Mapelastic smart coating at a thickness of 1mm to the detailing area ( on the horizontal and vertical surfaces) 

Install a 200mm wide strip of Mapetex Sel into the center of the first layer or Mapelastic Smart. Press will into the previous layer of Mapelastic smart whilst it is still wet with edge of a flat steel trowel or a roller to ensure Mapetex sel is fully embedded into the first layer of Mapelastic smart. Avoid application of excessive material in the corners and ensure that the Mapetex sel is fully dressing the corner.  

After 4+5 hours or when the first layer has dried, apply a further 1mm thick application of 

Mapelastic Smart to the top surface. Extending this layer beyond the Mapetex sel  by a minimum of 5cm.    

Any side or end overlaps of Mapetex sel fabric shall be at least 5cm wide.  

After treatment of all corners and penetrations apply a 1mm thick coat of Mapelastic smart to the remaining areas using a roller, brush trowel.  

Apply the second layer of Mapelastic smart after 4-5 hours or when the first layer has dried. 

Apply the 3rd later of Mapelastic once 2nd layer is dried.  

Coats shall be applied perpendicular to each other to ensure total coverage of any application imperfections. 

Mapelastic smart can withstand light foot traffic after drying. The membrane shall be protected against sharp object penetration or mechanical damage. 

Allow a minimum of 5 days for the Mapelastic smart to cure before application of ceramic tiles. At higher temperatures this period can be reduced to no less than 3 days after application.  

Once completed flooding to commence. Inspection for Flood Test to be submitted to the 

engineer representative after 72 hours. Final water level to be mark with tape indicating the date and time it was completed (Photo to be attached on the WIR). If incase there is a loss of water. Specialist to thoroughly inspect the area and re – do the surface where leakage is suspected until satisfactory.  



Civil Works (Installation of Stone and Coping).

Installation of the edge and tiling will follow the completion of cementitious waterproofing for the  wall and channels. The substrate must be adequately cured, mechanically sound, and free of loose particles, grease, oil, paint, wax and other deleterious material or surface contamination  should be sufficiently dry.  

Adhesive -  is applied to the substrate using a notched trowel. To achieve good adhesion, first apply a thin layer of adhesive on the substrate using the straight edge of the trowel. Immediately after; apply the desired thickness of using a suitable notched trowel, depending on the type and size of the tiles. (For adhesive mixing preparation.

Setting Out – The concerned area of the edge tile will be set out with reference to primary setting out points. Subcontractor surveyor to ensure that rows of edging are true in level and line should  be established prior to starting the works. 1 row of stones will be installed on the line of marking  which will serve as a benchmark of the installation of the pool. This activity should be executed  as per the approved tile layout drawing.  



Laying of Stone(s) / Coping Tiles – Before installing tile, the tile(s) shall be buttered and laying of  tile(s) work shall be starts after the cementitious waterproofing. Work should be planned to start  fixing from the top portion of the pool or Water Feature (Wall). Cut courses in both directions should be determined in advance. Where possible, cut tiles should be avoided by slightly adjusting the tile joints within the finish material if possible. To ensure that rows of tiles are true,  a level line should be established to position the starting course. Cut pieces around inlet, Vacuum and drainage points shall be installed properly. (WIR) to be submitted upon completion  of the tiling. 

Grouting of Joints – The joints must be dry, clean, free of dust and emptied at least 2/3 of tile thickness. The excess adhesive or mortal should be removed while still fresh. Before grouting, make sure that the installation mortar or the adhesive has set and released most of its moisture.  For application of grout – spread the approved grout with the float, making sure the joints are filled. Use the same float, but on the edge to removed excess grout. After finishing the grouting application.  Wet the surface thoroughly and emulsify with an abrasive pad for cleaning joints. Making sure not to wash-out the joints. 

Note: All joints should be raked out and cleaned from any contaminants prior to grouting.  Inspection request to be submitted upon completion of Grouting.
