    Waterproofing: Below Ground – Basements, Tunnels

    Below-ground waterproofing plays a critical role in protecting basements, retaining walls, lift pits, and foundation structures from water ingress, moisture migration, and long-term structural deterioration. Envirosystems provides a suite of engineered sheet and liquid-applied membrane systems designed to deliver durable, fully integrated waterproofing solutions in accordance with relevant Australian Standards and project-specific performance requirements.

    Our below-grade systems are developed to address the complex conditions encountered in subterranean construction, including variable ground moisture, hydrostatic pressure, and structural movement.

    • Multiple system options available, including HDPE sheet membranes, VLDPE sheet liners, and spray-applied polyurea membranes
    • Engineered to resist hydrostatic pressure, ground movement, and long-term soil-side exposure
    • Fully bonded membrane technologies designed to prevent lateral water tracking and moisture migration between the membrane and substrate
