Why Kerakoll?

Not all solutions are equal

Traditional paint-on treatment seals the wall — capillary pressure breaks through in 2–3 years. Kerakoll Biocalce works the opposite way: it lets the wall breathe so moisture escapes as vapour.

Our solutions

What exactly do we do?

Three complementary steps of the Kerakoll Biocalce system — moisture leaves naturally through the breathing wall.

Biocalce drying plaster

Microporous lime and pozzolan plaster. Releases moisture from the wall as vapour — blocks liquid water from re-entering. The wall gradually dries out.

Salt-managing protective layer

Salts crystallise inside the plaster, not on the surface. No peeling, no recurring stains — the surface stays clean long-term.

Mould removal + finishing

Full mould removal, disinfection, fungicidal primer. Healthy air guaranteed.

FAQ

Frequently asked questions

How long does the Kerakoll treatment take? +
On average 2–3 weeks, depending on basement size and moisture level. We give an exact timeline after assessment.
What's the difference between Kerakoll and traditional waterproofing? +
Traditional methods only coat the surface — capillary pressure breaks through in 2–3 years. Kerakoll penetrates inside the wall and seals pores via crystallisation. A lasting solution, not just cosmetic.
How much does wet basement treatment cost? +
Between 120,000–280,000 Ft/m², depending on moisture type and depth. We give an exact quote after a free site visit. No hidden costs.
