Mer-Thane 320
Elastomeric Urethane Waterproofing Membrane

Mer-Thane 320 is a high-performance, monolithic, cold fluid applied, single-component, bitumen modified, urethane polyurea waterproofing membrane. This user-friendly, seamless, impact resistant membrane provides superior adhesion, durability, chemical resistance, weatherability and flexibility. Mer-Thane 320 is available in horizontal and vertical formulations for use in a wide range of applications. Its superior elongation allows for substrate movement without membrane rupture while its chemical structure creates a tenacious adhesive bond engineered to protect concrete and plywood surfaces from deterioration due to water penetration and waterborne chlorides and to prevent lateral water migration between the membrane and base slab or vertical wall. It is chemically engineered to completely seal concrete substrates from moisture penetration during freeze-thaw cycling or high temperature/high humidity thermal cycling.

Mer-Thane 320 installs at a minimum 60 mils (1.52mm) dry finished thickness and is designed for use over properly prepared concrete and plywood substrates. The system incorporates fabric reinforced waterproofing for all flashing areas and at vertical walls and curbs that provides superior waterproofing protection at all vertical surface interfaces and thresholds.
