The Problem

Rising Damp in Masonry

If a horizontal barrier in the masonry is missing or has leaked over the decades, the masonry sucks up water from the ground like a sponge. The consequences are severe for the building structure, your health, and your heating costs – because damp masonry cools the walls down extremely quickly. Damage to masonry and plaster is the result. Mold spores can spread unchecked.

Peeling plaster and damp wall

Peeling Plaster & Damage Salts

The rising water transports harmful salts from the ground into the masonry. During drying, these crystallize, expand, and blow off plaster and wall paint.

Black mold and spores on a damp wall

Mold & Spores

Permanently damp walls offer the perfect breeding ground for dangerous black mold. The spores pollute the indoor air and endanger the health of your family.

Damp masonry and structural damage

Loss of Building Fabric

The water weakens the binder in the masonry. Over years, the stone loses its load-bearing capacity, which massively reduces the value of the building and leads to cracks.

The Solution

Retrofit Horizontal Barrier via Injection Process

With our highly effective, pressureless injection method, we establish an impenetrable barrier directly in your house's masonry. The WTA-certified special cream penetrates deep into the finest capillaries, binds molecularly with the masonry, and forms a continuous, water-repellent (hydrophobic) barrier layer with a thickness of a full 25 cm.
