Structural Waterproofing

Types A, B & C Waterproofing

Waterproof refers to the penetration of water (in its liquid state) and possibly under pressure.  Structural waterproofing is a general term within the industry that covers methods and treatments to describe waterproofing any structure.  Waterproofing or Structural Waterproofing is applicable to any construction under-ground or below ground level.

Damp proof refers to resistance to humidity or dampness.  Damp proofing is a general term that covers methods and treatments used to prevent damp from being absorbed through walls or floors into the interior of a structure above ground.

Basement Waterproofing


Water and moisture can cause damage to buildings and structures. Suitable provision must therefore be made, as early as the design stage, for project-specific waterproofing measures for construction, crack control and movement joints as well as penetrations to protect the structure, fit-out and furnishings, and prevent any operational disruption. 



The choice of waterproofing system or product is dictated by parameters such as The Intended use, Geotechnical conditions, form of construction, programme, accessibility.

Basement Waterproofing


Exterial Membrane
Type A

Type A (Barrier) Protection provides protection against ground water ingress by applying a waterproof material to the internal or external walls and floor slab of a basement or underground structure forming a barrier between the structure and any groundwater present.


Our RASCOtank can be used as a standalone solution or part of a twin or multi-system approach to waterproofing depending on your requirements.

Cavity Drain System

Type C Protection allows moisture or running water to penetrate through the external wall or floor of the structure and to travel behind the membrane in a controlled drainage system. Type C systems collect and manage any water ingress by diverting it into a designated safe point of disposal (such as a sump pump/package pump station).
