Description

Solvent-Free, Two-Part Epoxy Waterproofing System for Concrete and Masonry

Biokil Crown Epoxy Tanking is a high-performance, two-component, solvent-free epoxy coating formulated to provide a durable, chemical- and water-resistant barrier to internal concrete and masonry surfaces. Suitable for tanking basements, retaining walls, inspection pits, and plant rooms, it cures to form a tough, impermeable membrane that resists both moisture ingress and negative hydrostatic pressure. It also serves as a protective coating in areas subject to high humidity or chemical exposure.

Solvent-Free Formula: Low odour and safe for use in confined or sensitive environments.
Chemical Resistance: Resistant to a wide range of mild acids, alkalis, and cleaning chemicals.
