PREPRUFE® - This is a cold technology: no open flames, no primers and fillets, no special equipment. You can walk on the laid surface immediately and install reinforcement. The effectiveness does not depend on the compressive pressure or hydration and does not change from wetting-drying cycles. The membrane is chemically resistant to salts and sulfates — that is, it protects the structure in real, not laboratory conditions of groundwater.
PREPRUFE® 120S — for critical underground objects under constant pressure. This is the choice for structures that constantly operate below the groundwater level: protective structures, reservoirs, deep basements, infrastructure facilities. The system seals joints, corners, and penetrations with full adhesion, ensuring reliability where the cost of leakage is highest.
PREPRUFE® 150S — a proven solution for typical underground structures. An optimal balance of protection and cost for conditions of moderate and periodic water exposure: underground parking lots, technical and basement rooms. The membrane, with a thickness of 1.5 mm, withstands hydrostatic pressure up to 71 meters of water column, retains flexibility down to −29 °C, and has a vapor permeability of less than 0.1 perm — the structure is physically isolated from the soil, moisture, and contaminants.
Both systems are not just membranes, but a complete package: tapes for joints and corners, liquid membranes for penetrations, hydrophilic water stops for seams.
Hydromembrane — the official distributor of GCP Applied Technologies in Ukraine — will select the right grade for your object and accompany the project from calculation to installation.
