Versatile

Cementitious Waterproofing

Rigid and semi-flexible cementitious waterproofing for bathrooms, water tanks, basements and internal wet areas. It is breathable, it costs less than a membrane system, and where the substrate is not going to move it is usually the sensible choice.

Cementitious Waterproofing carried out in Thane & Mumbai — Mahadev Waterproofing

The method

How we actually do it

Waterproofing almost always fails at the small details rather than the big ones, so we follow the same sequence on every job. Here it is, and you’re welcome to hold us to it.

  1. Substrate saturated to a surface-dry condition

  2. Two-component slurry weighed and mixed to spec

  3. Two coats applied cross-directionally

  4. Cured under damp hessian so it reaches full strength

Questions

Cementitious Waterproofing: the questions we get asked

These are the ones that come up on the phone most weeks. If yours isn’t here, ring us and ask it — we’d rather answer it before you book than after.

When is cementitious the right choice over a membrane?

Where the substrate is not going to move: bathrooms, water tanks, basements and internal wet areas. It is breathable and costs less. On a terrace that expands and contracts in the sun, a flexible membrane is the better answer.

Can it be tiled over?

Yes — that is how it is normally used. It cures to a hard surface that takes tile adhesive directly.

How many coats do you apply?

Two, applied cross-directionally so the second closes any pinholes in the first, then cured under damp hessian so it reaches full strength rather than drying out early.

Leave a leak through one monsoon and it’ll cost you several times more to put right than it would this week. The inspection is free either way.
