Waterproofing

    Enviro BSL

    Enviro BSL is fully welded VLDPE basement liner system, purpose-built for high-risk below-grade structures where access is limited and performance must last. Designed for long-life waterproofing in basements, tunnels and other underground assets, it forms a continuous, watertight barrier engineered to resist water pressure, movement and aggressive ground conditions.

    • Designed for whole-of-asset durability (100+ year design life)
    • Welded, pressure-verified watertight integrity with proprietary compartmentalised resin injection redundancy system.
    • Proven performance + Australian-made delivery and technical support
