Cementitious Waterproofing for Tanks & Pools
Cement-based waterproofing built for water-retaining structures — pools, water tanks, basements and sumps — that resists both positive and negative water pressure.
Built for structures that hold, or hold back, water
Cementitious waterproofing bonds chemically with concrete to form a rigid, durable barrier. Because it resists both positive pressure (water pushing out, like a pool) and negative pressure (water pushing in, like a basement), it is the right system for water-retaining and below-ground structures.
It is safe for potable water tanks when the correct grade is used, and provides a strong base for tiling on pools and decorative water features.
Where cementitious systems are essential
- Swimming pools & water featuresConstant water contact needs a bonded barrier
- Water & storage tanksIncluding potable-water-safe grades
- Basements & lift pitsResists water pushing in from outside
- Concrete showing seepageDamp patches or efflorescence on walls
Four stages, done right
Surface Preparation
Clean and saturate the concrete; repair honeycombing and cracks.
Slurry Coats
Apply cementitious slurry in cross-directional coats.
Curing
Moist-cure the coating to develop full strength.
Flood Test & Handover
48-hour flood test where possible, then written warranty.

Tanks & Pool FAQ
Is it safe for drinking-water tanks?
Yes — we use potable-water-approved grades for tanks that store drinking water.
Can you tile over it?
Yes. Cementitious waterproofing is a strong, bonded base that tiles adhere to well — ideal for pools and water features.
What is negative-side waterproofing?
It is waterproofing that resists water pushing in from the outside — essential for basements and lift pits where you cannot reach the external face.
Do you flood-test pools and tanks?
Where practical we carry out a flood test (often 48 hours) to confirm water-tightness before handover.
Is the inspection free?
Yes — free inspection and a full photo report, no obligation.
