There are three main methods for protecting residential basements, cellars and other below-ground spaces from water ingress, these are known as Type A Basement Waterproofing, Type B Basement Waterproofing and Type C Basement Waterproofing systems. The application of these methods can depend on factors such as the structure and design of the building, the ground conditions and the intended use of the space.
Your property’s basement may require waterproofing protection if the building is subject to groundwater pressure bearing on the structure. If left untreated, the water may be able to penetrate the building. This can cause the surfaces of the walls and floors to become damp and increases the risk of flooding.
When installed correctly, waterproofing systems can provide effective protection with a ten-year guarantee, although the system may require some maintenance.
Type C Basement waterproofing uses an internal water management system to provide protection against water ingress in usable spaces.
Also known as drained protection, Type C waterproofing systems allow groundwater to penetrate through the external wall or floor of the property as far as the cavity between the external shell of the structure and the internal lining or finish. The groundwater is then collected by a Cavity Drain Membrane and diverted into controlled drainage, either a pumping chamber or external land drain, before being disposed of safely.
The amount of free water penetrating the cavity will depend on the volume of external groundwater and the level of hydrostatic pressure, as well as the resistance of the structure to water ingress. This makes the design and risk assessment stage of installing the waterproof system essential in order to avoid the constant supply of contaminated water to the structure, and the risk of flooding due to blockage.
Cavity Drain Membranes can be installed externally or internally to the walls and floors of the basement. Type C Basement Waterproofing systems are suitable for all structure types and are now often the preferred protection method against groundwater ingress due to its relatively low defect risk and easy, flexible installation.
