Cementitious Waterproofing

Cementitious systems are cement-based coatings, usually two-component, that bond into the substrate rather than sitting on it as a film. That makes them the right answer under tiles, inside tanks and anywhere the finished waterproofing will be permanently covered and inaccessible.

Leakproofs by Betterwork specifies and applies materials from this range across residential, commercial and industrial projects. Which one is right for your building depends on what the deep-scan inspection finds — the defect, the substrate and how much the structure moves — not on which product is best known.

What this range covers

Product types and systems within Dr. Fixit cementitious waterproofing:

• Flexible cementitious coatings
• Two-component waterproof membranes
• Polymer-modified cementitious waterproofing
• Waterproofing slurries for wet areas
• Tank and sump coatings

Where it is used

Bathroom and toilet sunk slabs, shower areas, kitchen and utility floors, water tanks and sumps, and basement walls treated from the inside.

How we choose between them

Flexibility is the variable. A rigid cementitious coating is fine on a stable tank wall; a bathroom slab that will be tiled and then walked on needs a flexible grade that can accommodate movement without cracking. Where the area will be tiled, adhesion of the tile adhesive to the membrane also has to be checked — not every waterproofing layer accepts tiling directly.

Every recommendation we make is written down before work is agreed, alongside the reason for it, so you can compare quotations on the same technical basis rather than on price alone.
