Bathroom Waterproofing in Mumbai

• Damp or peeling paint on walls next to the bathroom
• Stains or drips on the ceiling of the room or flat below
• Dark, crumbling or missing grout lines
• Hollow-sounding or loose floor tiles
• Swollen door frames or skirting near the bathroom
• A musty smell or mould that keeps coming back

1.Porous or cracked grout

Cement grout absorbs water. Once it cracks, every shower pushes water under the tiles.

2.Water trapped in the sunk

Many Mumbai bathrooms sit on a sunken slab filled with debris. When the waterproofing above it fails, water collects in the filling and seeps into the flat below for months.

3.Floor traps and pipe entries

Gaps around the drain and pipes are the most common leak points in a bathroom floor.

4.Concealed plumbing leaks

A leaking joint inside a wall or floor can look exactly like a waterproofing failure, so we test for it.

• Epoxy grouting and joint sealing

  Old grout raked out and replaced with non-absorbent epoxy grout; junctions and fixtures sealed with flexible sealant.

  Best forLeaks through joints, where the tiles and membrane are still sound

• Full re-waterproofing

  Tiles and screed removed, then a liquid or cementitious membrane across the floor and up the walls, with tape at corners and collars at drains.

  Best forFailed or missing membranes, and renovations

• Drain and penetration sealing

  Floor traps re-set with waterproof collars and pipe entries sealed with compatible sealants.

  Best forLeaks concentrated around the drain or pipes

• Plumbing pressure testing

  Supply lines isolated and pressure-tested, so hidden pipe leaks are found before any waterproofing is redone.

  Best forDamp that persists even when the shower isn't used
