1K Cold-Applied Polyurethane Membrane

1K Cold-Applied Polyurethane Membrane is a high-performance elastomeric waterproofing membrane specifically formulated for demanding structural applications. It features excellent resistance to high soil temperatures, hydrostatic pressure, chemical attack from groundwater sulfates, and structural movement, designed to support watertight integrity for roofs, below-grade substructures, and podiums.

Product Overview

1K Cold-Applied Polyurethane Membrane belongs to the Liquid Applied Waterproofing Membranes family. It is intended for roofs and terraces, balconies, podium details and complex penetrations. Final product selection must account for substrate condition, exposure, application method and compatibility with adjoining layers. 1K Cold-Applied Polyurethane Membrane is a high-performance elastomeric waterproofing membrane specifically formulated for demanding structural applications.

Application Guidelines & Installation Method

Step 1: Ensure the substrate is clean, dry, sound and free from contaminants.

Step 2: Apply the recommended Geobit primer and allow it to dry.

Step 3: Apply uniformly to the TDS-specified thickness, coverage and number of coats.

Step 4: Treat joints, corners, penetrations, drains, upstands and terminations.

Step 5: Protect the completed waterproofing from traffic, weather, damage and subsequent works until fully cured.

Standard Compliance

Conforms to ASTM, BS EN, and local municipality green building regulations. Verified through independent laboratory testing and certified project listings.
