Shower waterproofing in Sants-Montjuïc.

Why showers start to leak

In areas such as Sants, Sants - Badal and Hostafrancs the bathroom often sits directly above a neighbour's and drains into an old shared soil stack. Before lifting anything we check whether the leak comes from the shower or the communal pipe, and we carry rubble down the stairs in sacks with the entrance protected.

For level-access showers in areas such as La Bordeta and La Font de la Guatlla we rebuild the screed with a continuous fall to the drain or linear channel, with no spots where water can sit. The membrane goes under the tile adhesive and bonds to the drain with its own connection collar.

With more than 20 years rebuilding showers we know what to look for on the visit; the quote is detailed and in writing, and the team works carefully and cleans up afterwards. Also nearby: Eixample, Les Corts and Ciutat Vella.
