Under Slab Waterproofing

Under Concrete Slab Waterproofing System

Waterproofing Under Concrete Slab

Below ground waterproofing is as important as your foundations supporting the entire structure.

  • Without the combination of sound footings and waterproof structures a building will deteriorate rapidly.
  • Below grade systems are often inaccessible for repairs and extremely costly if modifications or rectifications are necessary at a future date.
  • Positive-side waterproofing systems are post-applied to the surface of the substrate directly exposed to moisture, typically the exterior side of the foundation wall.

Below Ground Waterproofing - Design & Planning

Durability of design and materials is mandatory with below grade waterproofing systems.

Below ground waterproofing is one of those areas usually unseen and I am not sure if it is "out of sight, out of mind" mentality, however it is an area of construction often neglected.

Best Waterproofing Product

  • The traditional plastic barrier used for under slab protection is a moisture barrier and is NOT a waterproof membrane.
  • Liquid Applied Membranes are particularly suitable for gas vapour barriers for mitigating methane & VOC intrusion.
  • Waterproofing Membranes installed under concrete slabs must provide permanent vapour, gas, chemical & water protection.
  • Liquid Applied Waterproofing provides a seamless and flexible membrane that will also move with the concrete foundations.
  • This means there are no JOINS or SEAMS - which are often areas of potential weakness due to possibility of tears during construction & over time.

Spray apply Liquid Rubber Membranes cure to form a continuous seamless barrier providing waterproof protection horizontally, vertically up walls and around penetrations, pipes and upturns.

Liquid Membranes For Basement Waterproofing

Spray Apply Waterproofing Membrane

Liquid Membranes cure to form a durable barrier providing permanent water protection.

  • Liquid Waterproofing Systems are engineered for below slab construction.
  • The Membrane bonds integrally to poured concrete for use below slabs or basement walls - both horizontally & vertically.
  • Remains unaffected by ground settlement beneath slabs.
