Unique sealing system of a new generation on the bentonite basis — trusted by contractors across Europe.
For foundations, basements, and below-grade structures.
For stopping active water leaks in concrete structures.
For underground construction drainage and repair.
For existing water-bearing structure repair.
Bentonite is a natural clay mineral. When activated by moisture, it expands up to 300 % of its dry volume, creating an impermeable molecular barrier that stops water under pressure.
Molecular swelling creates back-pressure that seals even the smallest capillary gaps.
If the structure shifts, bentonite re-seals automatically. The barrier regenerates.
Reliable against water under pressure up to 7 bar — proven in dams and tunnels.
Unaffected by most chemicals, salts, and hydrocarbons found in soil and groundwater.
Every product is designed for a specific sealing challenge. Full technical documentation available for each.
Bentonite swelling tapes in 10–25 mm profiles. With or without protective foil for poured joints.
Bentonite geocomposite liners with HDPE reinforcement for horizontal and vertical sealing.
Bentonite-based swelling adhesive and waterproofing compound in cartridge, pail, and sheet format.
Granulated and milled activated bentonite for bulk sealing, backfilling, and custom applications.
Our systems have been installed across the Czech Republic and Europe in residential, commercial, and infrastructure projects.
