When waterproofing residential basements, there are three main methods known as Type A basement waterproofing, Type B basement waterproofing and Type C basement waterproofing. These methods provide protection to prevent groundwater from entering the basement or below ground structures and causing water ingress. The application of each waterproofing systems depends on the structure, ground conditions and the intended use of the building.
Your basement may require waterproofing if the structure of the building is subject to groundwater pressure bearing on the structure. When left untreated groundwater can enter the structure, causing the surfaces of the walls and floors of the basement to become damp or even cause flooding. Once installed correctly, most basement waterproofing systems usually have a guarantee of around ten years, providing the system is serviced and maintained as necessary.
Type A Basement waterproofing uses a barrier system to keep a space dry and is considered the traditional method for waterproofing the basements of residential homes in the UK.
This method protects against groundwater ingress when water infiltrates property through the basement by installing a separate barrier system that is applied to the structure. This type of barrier protection, sometimes known as Tanking depending on the form, requires the application of waterproof material to the external walls and floor of the basement to form a barrier between the groundwater and structure.
Depending on the chosen material, Type A barrier protection can involve applying the waterproofing material to either the internal or external surfaces of the wall or floor. Applying the material to both the internal and external wall or surface can provide a double layer of protection against water ingress. Some materials can be applied in between the wall and floor surfaces too, this Type A waterproofing technique is known as sandwiched waterproofing.
When applied correctly, the barrier waterproofing system can effectively withstand groundwater from entering the basement under pressure. A thorough assessment and survey of the structure must be carried out to ensure the building is suitable for applying a Type A waterproofing system.
Some of the materials and products suitable for Type A Basement waterproofing include:
