Seals

Nothing can get through: water-tight protection for the fabric of your building

The seals protecting the fabric of the building must meet the highest demands. After all, penetrating water nearly always leads to damage to the building's fabric. It is essential that leaks are sustainably sealed. We are your specialists for the job.

What we offer:

The balcony is often the most exposed element of a building. We'll get your balcony back up to scratch:

  • Repairs to flaking and local separation

Polyurea is an extremely durable, spray-coated flooring solution for industrial and commercial applications with high mechanical or chemical loads. The seamless, elastic system impresses with its exceptional tear resistance, fast curing and resistance to moisture, chemicals and temperature fluctuations. Thanks to reactive two-component technology, polyurea can be applied in the shortest possible time - even for complex geometries or large-area applications.
