Roof top swimming pool- challenge to get total watertight structure-Solutions from BPT group
Proper waterproofing is critical when constructing a swimming pool over a terrace slab of a building. Without adequate waterproofing, several issues can arise, potentially causing significant damage to the structure and leading to expensive repairs. Here’s why it’s important:
1. Preventing Water Leakage
- Structural Integrity: Water leakage can seep into the building’s concrete, corroding steel reinforcements and compromising the structural integrity.
- Damage to Interiors: Leaks can damage ceilings, walls, and flooring below the terrace, leading to peeling paint, mold, and weakened plaster.
2. Thermal and Moisture Protection
- Waterproofing acts as a barrier, preventing moisture from entering the slab, which could otherwise cause thermal expansion or cracks due to fluctuating temperatures.
3. Avoiding Long-term Maintenance Costs
- Poor waterproofing leads to frequent maintenance issues such as patching leaks or even resurfacing. Investing in proper waterproofing during construction minimizes these expenses over the pool’s lifecycle.
4. Enhancing Durability
- Proper waterproofing prolongs the life of the terrace slab and the pool by protecting against issues like: Efflorescence (salts coming out of concrete) Deterioration caused by chlorine or pool chemicals penetrating the slab
Key Waterproofing Considerations for a Terrace Pool
- Waterproofing Membranes: Use high-quality flexible membranes like polyurethane, EPDM rubber, or bituminous membranes.
- Drainage Design: Incorporate proper slopes and drainage systems to avoid water stagnation.
- Protective Layers: Use protective screeds or geotextiles over waterproofing layers to prevent mechanical damage during construction.
- Joint Sealing: Ensure that expansion and construction joints are sealed with durable sealants like polyurethane or silicone-based materials.
- Testing:Conduct a water ponding test after waterproofing to ensure the slab is leak-proof before proceeding with the pool construction.
