DampSafe 601 Slimline

Flat Loose Laid High Grade Flooring Membrane – Primarily for isolating moisture sensitive flooring from dampness in the floor slab, but can also be used as the floor membrane as part of the Newton CDM System, when the survey has ascertained that there is no risk of water entering through the body of the slab.

  • Advanced Moisture Isolation: Effectively isolates moisture-sensitive flooring from dampness in floor slabs, ensuring long-term protection.
  • Early Installation Capability: Can be installed above uncured slabs and as soon as concrete is walkable, speeding up construction timelines.
  • Exceptional Strength: Offers outstanding load-bearing capacity, capable of withstanding over 1000kN/m², ensuring durability under heavy loads.
  • Versatile Application: Functions as both a floor membrane in the Newton CDM System and a high-load DPC in structural block walls, providing versatile waterproofing solutions.
  • Chemical and Biological Resistance: Inert and highly resistant to water, alkalies, hydrocarbons, saline solutions, organic acids, minerals, bacteria, fungi, and other organisms, ensuring resilience in diverse environmental conditions.
