Designing Basement Waterproofing Systems

The key design considerations must be kept in mind while designing a basement waterproofing system

Waterproofing

Basements are susceptible to the ingress of moisture and contaminants from the ground. For this reason, a waterproofing system will usually be required. Guidance on the requirements for basement waterproofing systems is given in BS 8102:2009, “Code of practice for protection of below ground structures against water from the ground”.

The choice of waterproofing system will depend on a number of factors such as the method & type of basement construction, the depth below ground, and the proposed end use. The example designs on this website are intended to demonstrate how BS 8102 compliant solutions can be achieved for some of the most common basement waterproofing scenarios.

Ventilation

In addition to dampness from the ground, basements are also commonly affected by condensation issues due to moisture-laden air within the basement structure. For this reason, the waterproofing systems described in this guide will usually need to be supplemented by mechanical ventilation. A waterproofing design specialist (see below) will be able to advise on suitable ventilation options depending on the proposed end use (e.g. car parking, document storage etc...)

Design Specialist

A waterproofing design specialist with a CSSW qualification should be consulted at the design stage. Please contact our technical department on 01403 210204 or email [email protected] for details of suitable basement design specialists in your area.

Design resillient basement structure

E.g. Reinforced concrete structure, simple shape, minimal service penetrations

Choose suitable waterproofing system

Choose a waterproofing system appropriate for the type of basement. The designs in this guide are a useful starting point.

Maintenance

Drainage channels and sump pumps should be serviced on a regular basis.
