Warning Signs

Critical Swimming Pool Waterproofing Warning Signs

Recognize these early indicators of water damage before minor moisture issues cause expensive structural decay.

Unexplained water loss

Losing more than a quarter-inch of water a day usually indicates a structural leak, not just evaporation.

Falling pool tiles

Water getting behind the tiles due to failed waterproofing causes the adhesive to fail and tiles to pop off.

Calcium nodules (stalactites)

White crystalline growths on the pool surface or exterior shell indicate water leaching through the concrete.

Rust stains in the pool

Water reaching the steel reinforcement mesh causes rust that bleeds through the plaster or tiles.

Cracking coping stones

Movement or water ingress expanding behind the edge beams of the pool.

Damp spots on exterior pool walls

For above-ground or infinity pools, wet patches on the outside wall mean the internal seal is broken.

Our Process

Our Proven 4-Step Process

From Problem to Peace of Mind

STEP 1

Concrete Shell Grinding & Cleaning

The pool shell is pressure washed and key-ground to remove form release agents, laitance, and dust to guarantee concrete-to-membrane adhesion.

STEP 2

Hydrostatic Pressure Barrier

A specialized 2-part epoxy moisture barrier is applied to resist both positive water pressure from inside the pool and negative groundwater pressure from outside.

STEP 3

Joint & Fitting Detailing

All returns, main drains, skimmers, light niches, and construction joints are meticulously sealed using flexible elastomeric detailing compounds.

STEP 4

High-Durability Flexible Membrane

Two thick coats of flexible cementitious or polyurethane pool membrane are applied, providing a watertight base suitable for direct tile installation or render.

Tile grout and the tile adhesive are naturally porous and will not hold water. The specialized cementitious waterproofing membrane applied beneath the tiles is the actual barrier that holds the water in and protects the structural concrete shell from rusting.
Yes. Our swimming pool membranes are engineered with high chemical resistance to withstand continuous submersion in saltwater, chlorine, ozone, and fluctuating pool pH levels without softening or delaminating.
Yes, absolutely. Tile grout and the tile adhesive are naturally porous and will not hold water. The specialized cementitious waterproofing membrane applied beneath the tiles is the actual barrier that holds the water in and protects the structural concrete shell from rusting.
The entire process—including substrate repair, moisture-tolerant priming, application of two thick coats of cementitious membrane, and proper curing—typically takes 3 to 5 days. Following this, a 24-hour flood test is conducted before the pool can be tiled.
In most cases, spot repairs on pebblecrete are prone to failure. To guarantee a leak-free repair, we typically advise stripping the interior back to the bare concrete shell, applying a full waterproofing membrane system, and then resurfacing the pool completely.
Yes. We use premium, heavy-duty cementitious membranes specifically engineered for constant chemical immersion. They are highly resistant to chlorine, salt chlorinators, ozone systems, and the extreme pH fluctuations common in swimming pools.
