Waterproofing

A leak is solved at its source.

Water always finds the weakest point. Usually that is a junction: between roof and facade, around a chimney or below a window. That is where we start.

Understand first. Then build.

What we pay attention to

Leak detection

We find where the water gets in. That is rarely where you see the stain.

Roof junctions

Leadwork and junctions around chimneys, roof windows and abutments.

Facade junctions

Sills, thresholds and plinths finished so water is drained away.

Flat roofs

Upstands, outlets and edges decide whether a flat roof stays dry.

Waterproofing systems

Membranes and foils suited to the substrate and the rest of the build-up.

Lasting solution

No temporary sealant, but a repair that is right for the construction.

Our approach

Recurring damp problems almost always have a technical cause. Repairing only the visible damage usually means the problem returns.

We look at roof and facade as one whole and explain where the water gets in, why, and what is needed to solve it for good.
