- Shower waterproofing
Shower waterproofing no more leaks into the flat below.
We trace where the water is escaping, rebuild the base with a continuous membrane and test it for leaks before the finish goes on.

What shower waterproofing includes
-
Source of the leak
We find out whether water escapes through grout, waste or pipework before opening up.
-
Opening up the area
We lift the tray and shower tiles, leaving the rest of the bathroom alone.
-
Falls to the drain
We rebuild the base so water runs to the waste and never sits.
-
Continuous membrane
Membrane across floor and walls, with tape at corners, pipes and drain.
-
Flood test
We flood the base and check for any loss before closing it up.
-
New finish
Tray or tiles laid on top, with epoxy or mould-resistant grout.
How we deal with a leak
First we visit the shower and, where possible, the affected ceiling. We check grout, waste and pipes and, with the diagnosis, prepare a detailed written quote.
A site manager coordinates the work: we open up the area, rebuild the falls, lay the membrane with reinforcement at critical points and carry out a flood test.
Once the test is passed we close up with a tray or tiles, seal everything and leave the bathroom clean and ready to use.

Frequently asked questions
01Is replacing the grout enough to stop the leak?
Only if the grout is the problem and the membrane underneath is sound. If water has already reached the floor slab, the shower has to be lifted and waterproofed again.
02What is a flood test?
We plug the drain and fill the waterproofed base with water. If the level holds and no damp appears below, the finish can go on.
03Does a tiled walk-in shower need more care than one with a tray?
Yes. Without a tray, the membrane and falls are all that hold the water back, so they must cover the whole floor and run up the walls.
04How much does a complete renovation cost?
There is no single price. The estimate depends on the condition and size of the home, the scope of the project, materials and work required. Tell us your idea so we can assess your specific case.
05How long does a renovation take?
It depends on the type of home, the scope of the work and the project's constraints. Once we have studied the renovation, we can give you a more accurate estimate.
06Can a home be renovated while people still live in it?
It depends on the scope, estimated duration and condition of the home. When we study the project, we will assess whether it is feasible and what precautions or alternatives should be considered.
07How can I request an estimate?
Choose what you want to renovate, tell us whether the work is partial or complete, and leave your name, phone number and email. This lets us provide initial guidance. You can also write to us directly on WhatsApp.
