Shower waterproofing in Sant Andreu.
We stop shower leaks in Sant Andreu at the base: a continuous membrane, falls towards the waste and a water test before the finish, so the ceiling below can dry out.

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.
Why showers start to leak
In older buildings in areas such as Sant Andreu and La Trinitat Vella many showers were built on joist-and-vault floors with no membrane under the tiles. When water gets through, the stain appears in the flat below, so we arrange access with the neighbour to see the ceiling and work within the building's set hours.
When the leak comes only from the joints, in homes in areas such as La Sagrera, Navas and El Congrés i els Indians it can be enough to rake out the grout, seal with a waterproofing product and regrout in epoxy. We decide that only after a water test shows the membrane underneath is intact.
After the visit you get a written quote setting out each stage of the waterproofing. We protect the rest of the bathroom, clear the rubble and leave it clean. Other nearby areas we cover: Nou Barris, Horta-Guinardó and Sant Martí.

We work in Sant Andreu in areas such as Sant Andreu, La Trinitat Vella, La Sagrera, Navas, El Congrés i els Indians, El Bon Pastor and Baró de Viver, and also nearby: Nou Barris, Horta-Guinardó and Sant Martí.
02Is 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.
03What 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.
04Does 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.
