Waterproofing

How to choose: Waterproofing

Waterproofing is a pool's invisible insurance: it sits beneath the finish, but if it fails the whole finish comes off. Detailing — corners, movement joints, pipe penetrations — matters as much as the material itself. Done properly, it needs no intervention for the life of the pool.

Ground movement

Where settlement or vibration is expected, flexible cement-based systems are preferred.

Detail points

The great majority of leaks start at corners, joints and pipe penetrations, not open surfaces.

Water chemistry

Salt and thermal water call for a separate check of the material's chemical resistance.

Testing and handover

Never accept waterproofing without a full water-retention test before tiling.
