Our Advantages

Non-invasive

Breathable

Durable

Before and after shots of a basement wall treated with duracrista’s moisture solution.

No need to drill holes in the masonry or excavate half the building. You simply need to plaster your walls with Isokristall.

With Isokristall, your masonry itself becomes the waterproofing layer. The active ingredients use existing moisture to penetrate deep into the wall, binding water molecules and converting them into a mineral structure. The result: A permanent, water-impermeable "white tank."

Isokristall lasts significantly longer than conventional methods and comes with a 15-year guarantee. Up to 30 years upon request.

* At the MFPA Leipzig testing institute, a maximum test pressure of 0.75 bar was possible. Isokristall passed this test without any issues (see test report).

In Germany, buildings located up to 15 meters below groundwater level have already been waterproofed and have withstood hydrostatic pressure of 1.5 bar for many years.
