Waterproofing for balconies and terraces

The substrate, the waterproofing layer and the junctions at thresholds, edges, movement joints and drains. We set out the details in our quotation.

Under tiles we apply under-tile waterproofing — 2K slurry or liquid membrane. If the balcony is to stay without tiles, we lay hot-air-welded EPDM RESITRIX membrane, with patches around the railing posts. We choose the solution during the site visit.

Before the layers and finish are laid. A site visit helps match the build-up to the structure, the falls and the intended surface.

Sometimes, yes — if the old tiles are firmly bonded to the substrate (they don’t sound hollow when tapped) and we apply new waterproofing over them. With cracked tiles, a damp substrate or the wrong fall, we chip the tiling off down to the slab.

Most often because of water that has got under the tiling — through missing or damaged waterproofing, a leaking threshold, corner or outlet, or voids under the tiles. As it freezes, it breaks up the adhesive and pushes the tiles off the substrate.

We give a 5-year guarantee on completed work. The scope and terms are set out in our quotation, according to the chosen system and the scope of the job.
