TREMproof® Amphibia™

A revolutionary sheet-applied waterproofing membrane consisting of three active layers – a watertight EPDM barrier, an active core with the ability to self-seal when punctured or penetrated, and an active barrier. Additionally, a non-woven fabric layer promotes the mechanical adhesion of the membrane to the concrete.

Self-Healing, Self-Sealing, Hydro-Reactive, Sheet-Applied Waterproofing Membrane

TREMproof® Amphibia™ waterproofing membrane is self-healing, self-sealing and self-repairing. It has three active layers – a watertight EPDM barrier, an active core with the ability to seal when penetrated and an active barrier which seals the overlap and helps resist lateral movement of water. Also, a non-woven fabric layer promotes the mechanical adhesion of the membrane to the concrete., TREMproof® Amphibia™ waterproofing membrane is designed for use over lagging on blindside walls, below-grade walls, pile caps, grade beams, under slab and buried forms such as elevator pits.

Product Description

TREMproof® Amphibia™ is a self-healing, self-sealing, and self-repairing sheet-applied waterproofing membrane. This co-extruded, watertight membrane comprises three active layers: a watertight EPDM barrier, an active core that seals when penetrated, and an active barrier that seals overlaps and resists lateral water movement. Additionally, a non-woven fabric layer promotes mechanical adhesion to concrete surfaces.

Key Benefits

  • Self-Healing & Self-Sealing: Active core and barrier layers automatically seal punctures and overlaps, ensuring continuous waterproofing protection.
  • Hydro-Responsive: Designed to activate upon contact with water, enhancing its sealing capabilities in wet conditions.
  • Robust Adhesion: Non-woven fabric layer ensures strong mechanical bond to concrete substrates.
  • Versatile Application: Suitable for blindside walls, below slab-on-grade, and submerged conditions.
  • Durable & Flexible: Exceptional elongation and crack-bridging properties provide long-term performance.

Best For

  • Blindside walls
  • Below-grade walls
  • Under slab-on-grade
  • Pile caps
  • Grade beams
