Bathroom Waterproofing Without Demolition in Karachi
Stop bathroom leakage to the ceiling below using transparent and injection systems with no tile breaking.
Bathroom leaks damage the ceiling of the room below, and breaking the floor is expensive and messy. Our no-demolition methods stop leakage without removing your tiles, fittings or sanitary ware in most cases.
Problem: why bathroom waterproofing without demolition is needed
Tile grout, silicone joints and pipe connections fail over time. Water passes into the slab and appears as stains on the floor below.
- Stains and dampness on the ceiling below a bathroom
- Water marks on adjacent walls
- Loose tiles and cracked grout
- Water leaking around the shower or toilet floor trap
Our solution
We locate the leak, seal grout lines and pipe penetrations with a transparent waterproof liquid, and use injection grouting into cracks and floor traps from the bathroom surface.
