Types of waterproofing in the bathroom

There are various ways to seal the shower correctly and sustainably. For example, sealing membranes and sealing strips are a good way to seal the shower or bathtub. This form of waterproofing provides long-term and effective protection against moisture behind and under the shower. It is waterproof and water vapour-retardant.

In addition to waterproofing membranes, there are also variants of liquid foil or sealing slurry. Liquid foil is very easy to install and can withstand low water loads. Sealing slurries are well-suited for heavier loads on the joins.

Installing a waterproofing membrane

A waterproofing membrane can only be installed once all details such as connections, corners, pipe penetrations and the floor drain have been sealed. The waterproofing membrane is then simply laid out and cut to size with a cutter knife. The membrane is then glued in place using thin-bed mortar. Work must be done quickly. In the case of previously bonded waterproofing, an overlap of at least 5 cm must be observed for new membranes. For large areas, several membranes can also be laid next to each other. In this case, however, the seam area must be sealed separately. In order to obtain a flat surface, the waterproofing can be worked with a rubber roller or a trowel.
