    Waterproofing: Below Ground – Lift Pits, Stair Cores, Footings

    High-performance waterproofing systems engineered to deliver long-term protection for lift pits subjected to continuous groundwater exposure and hydrostatic pressure. Envirosystems provides both sheet and spray-applied membrane technologies designed to achieve complete encapsulation of the structure, while accommodating chemical exposure, substrate movement, and complex construction detailing.

    These systems are selected to perform in permanently wet environments where durability, adhesion, and watertight integrity are critical to protecting structural elements and building services.

    • Designed for permanent immersion and sustained hydrostatic pressure conditions
    • Fully bonded membrane systems that minimise the risk of water tracking or lateral migration
    • Suitable for confined-space applications and complex geometries, including penetrations, joints, and irregular substrates
