Type C Waterproofing

Type C Waterproofing – Drained Protection (Cavity Drainage Membranes)

Type C Waterproofing systems allow water to flow freely through a cavity between the exterior and interior walls of a basement (by way of a cavity drain membrane), before it is channeled via perimeter drainage channel into a sump, from where it can then safely be drained or pumped away via a pump unit. It is by far the most trouble free and effective form of waterproofing a structure in the ground, especially where the basement area is to be used for habitable accommodation.

Benefits and considerations of Type C Waterproofing

- Ability to be installed in any weather and groundwater ingress conditions.

- The offer of Predictable waterproofing results.

- The ease of and speed of follow-on  trades.

 - Ease of repair-ability should anything go wrong.

 - Waterproofing capability can be tested during construction.

  – Requires planned ongoing maintenance – inspection and rodding facilities available

 - Must be designed and installed by professionals – given requirement to collect water
  ingress and drain it effectively / efficiently.
