Visqueen TorchOn Tanking Membrane – A heavy duty waterproofing membrane

Visqueen TorchOn Tanking Membrane is a robust waterproofing membrane, used for heavy duty tanking and gas proofing applications. It can be used both vertically and horizontally above and below ground level to prevent the ingress of water.

  • Robust tanking membrane
  • Suitable for gas protection applications
  • Torch bonded laps provide a homogenously sealed junction
  • Ideal for cold weather application
  • Used to waterproof basements, car parks, lift pits, reinforced concrete slabs, retaining walls

Visqueen TorchOn Tanking Membrane should be applied as a two layer system when used as a tanking system for below ground structures where high levels of hydrostatic (water) pressure exist in conjunction with an internal waterproof render in accordance with BS8102: 2009 type A structures.

Visqueen TorchOn Tanking Membrane can be used as a single layer system when used as a horizontal damp proofing membrane or in low risk situations. All laps should be a minimum of 150mm. The loading screed or floor slab which is laid on top of the membrane should be adequate to resist any hydrostatic water pressure.
