How to Check for Leakage Before Using Your Swimming Pool
Swimming pool waterproofing becomes essential when your pool starts leaking silently. Before you start using your swimming pool, it is important to ensure there are no leaks. Begin by filling the pool to its normal water level and marking the waterline. Over the next 3 to 7 days, carefully monitor the water level without using the pool or running the filtration system.
If the water level drops by more than 6 to 8 inches within a week — and there has been no rainfall or filter back-washing — it’s a clear sign of leakage. This is often caused by cracks in the plaster, damaged tile joints, or failure of old waterproofing layers.Learn more about how to identify hidden leaks.
Once the leak is confirmed, Waterseal provides expert swimming pool waterproofing services in Ahmedabad. For customers outside Ahmedabad, we offer easy-to-use DIY waterproofing kits with step-by-step guidance — through which you can call any local house painter and get the work done as per our instructions, effectively stopping the leakage.
Swimming Pool Waterproofing Process – Step-by-Step Guide to Fix Leaking Pools
Swimming pool waterproofing is essential when you notice signs of leakage, especially in old or damaged pools. Even a small crack or joint failure can result in water loss of 6 to 8 inches per week, weakening the structure over time.
Waterseal provides a reliable, long-lasting solution for leaking pools through our proven PSv-Premix coating system. Below is a detailed breakdown of the professional steps we follow to ensure your swimming pool is completely waterproof and leak-free:
1. Surface Cleaning
We start by cleaning all surfaces of the swimming pool — including sidewalls and floor — using a wire brush or grinder machine. This removes dust, dirt, moss, algae, and other debris. Proper surface cleaning is vital for chemical bonding and long-term waterproofing performance.
2. Crack Inspection and Widening
Next, we conduct a thorough inspection of the entire pool to detect even the smallest cracks and weak joints. All identified cracks are slightly widened using a grinder machine. This allows us to inject more PSv-Premix waterproofing chemical deep into the cracks for better sealing.
3. Final Pressure Wash
After grinding and crack opening, we pressure wash the entire swimming pool again. This ensures no dust, particles, or loose debris remain on the surface before the coating application.
4. Primer Coating (1st Coat)
We prepare a primer coat using a 1:2 ratio — one part PSv-Premix and two parts clean water. This mixture is applied over the entire pool surface using a brush, roller, bamboo stick, or spray machine. This primer helps seal micro-pores and prepares the surface for further coating.
5. Crack Sealing with PPC Mat (2nd Coat)
While the primer layer dries, we focus on sealing the remaining visible cracks and joints. A 1:1 mix of PSv-Premix and clean water is applied along with PPC Mat (polypropylene-coated fabric). This creates a strong bridge over cracks, ensuring they won’t reopen due to water pressure or structural stress.
6. Strong Waterproofing Layers (3rd & 4th Coats)
Now comes the core waterproofing stage. Two more coats are applied using the same 1:1 mixture of PSv-Premix and water. The first coat is applied vertically, and once it dries, the second coat is applied horizontally. This cross-layer method forms a durable, flexible, and water-resistant membrane.
7. Optional Topcoat – PSv Super Repellent Coating
For pools that need extra durability and UV resistance, we recommend an optional final coating using Waterseal PSv Super Repellent Coating. It enhances the overall life of your waterproofing layer and provides a glossy, easy-to-clean finish.
After Waterproofing: What to Do
Once all coatings are complete, let the swimming pool dry naturally for 5 to 7 days. After that, fill the pool and monitor the water level for the next 7 days. If there's no drop, your leakage is resolved. You can then drain the test water, refill with clean water, and enjoy your swimming pool worry-free.
