1 RECTIFICATION OF WATERPROOFING IN AGED SWIMMING POOLS ON ROOFTOPS & ABOVE CAR PARKS WITH FRP Jeda Pte Ltd Tel:

2 ISSUES WITH LEAKING SWIMMING POOLS Most swimming pools in condominiums here are built on top of underground facilities like car parks. Rooftop swimming pools are built on top of the topmost units, usually also the most expensive units. Therefore, leaking swimming pools can cause extensive and irreparable damage to private properties. Most leaks are caused by cracks in the concrete and defective membrane waterproofing. Current total repair method for swimming pool leaks is time-consuming and costly, while some methods are not permanent.

3 TYPICAL COMPONENTS OF A SWIMMING POOL Membrane Waterproofing Protection Cement Mortar cum Tile Bed Swimming Pool Tiles Concrete Cracks in concrete

4 COMMON RECTIFICATION METHODS 1. TOTAL REPAIR Remove existing tiles, protection cement mortar and membrane waterproofing, replace the membrane waterproofing then reinstate the protection cement mortar and tiles. 2. GROUTING STRUCTURE BELOW SWIMMING POOL Grout either PU, epoxy or Sovereign latex grout from below the pool to seal the cracks and stop the leaks. 3. FRP COATING Remove existing tiles only, then apply 3 coats of FRP waterproofing and a coat of protection top coat as a fresh waterproofing layer.

5 TOTAL REPAIR Most swimming pools in Singapore have membrane waterproofing installed as the primary method of waterproofing. The only viable method of repair is to remove the current membrane waterproofing and replace it with a new layer. Doing so requires 1. Removing the existing pool tiles, tile bed cement mortar screed and membrane waterproofing 2. Applying a new layer of membrane waterproofing 3. Redoing a new layer of tile bed cement mortar screed 4. Reinstating pool tiles

6 GROUTING BELOW SWIMMING POOL SLAB Grouting below the swimming pool slab does not require the removal of existing tiles, tile bed cement mortar screed and existing membrane waterproofing. Most commonly used grouts in Singapore are PU and epoxy. However, each has their own shortcomings: PU grout can stop water immediately but only lasts a maximum of 3 4 months Epoxy grout requires that the structure has less than 5% moisture content and it is extremely difficult to pinpoint the leaking points in order to carry out the grouting

7 GROUTING BELOW SWIMMING POOL SLAB Sovereign latex grouting lasts much longer than PU grout and does not have stringent requirements like epoxy grout. However, sufficient structural thickness of 400 mm is necessary in order to perform Sovereign latex grouting. Grouting needs to fulfill special requirements & is not a long-term solution

8 THE BEST SOLUTION: FRP WATERPROOFING The most economical and best solution for pool leak repairs is to use FRP coating. FRP (Fiber-Reinforced Plastics, or Fiber-Reinforced Polymers) waterproofing coatings have inherent superior resistance to UV and chemicals. Stronger material vs. membrane waterproofing, has high strength-to-weight ratio. Cost & Time Savings unnecessary to remove all components (except the tiles); the seal coat and FRP resin comes in variety of colors so there s no need to reinstate the tiles. No need to reinstate tiles the FRP resin and protection coat come in a variety of colors and can meet clients requirements for any color for their swimming pool

APPLICATION PROCESS 1 2 3 4 5 6 Drain the swimming

Apply 3 layers of FRP resin & fiber mat Apply seal

9 APPLICATION PROCESS Drain the swimming pool Remove all tiles and expose the underlying concrete tile bed Touch up the underlying concrete while ensuring that the gradient is kept Apply primer Apply 3 layers of FRP resin & fiber mat Apply seal (or protection) coat (available in various colors) OR Reinstate tiles

10 A Swimming Pool with FRP Waterproofing

11 SUMMARY Save time and money with FRP waterproofing for repairing leaks in swimming pools. FRP waterproofing is more durable than membrane waterproofing & has strong inherent resistance to chemicals. Both the FRP resin and protection coat come in various colors so there s no need to reinstate tiles. Warranty of 10 years, with minimal to no maintenance required.
