Standards & Specifications

Basement Waterproofing Standards

There are a number of different national basement waterproofing standards relating to the waterproofing of below ground structures. Generally these are defined according to the type and nature of the structure that is to be waterproofed. Unfortunately there are currently no agreed International (ISO) or European Standards (EN) in this important area. However there is a very useful and recently revised (October 2009) and updated British Standard in relation to the waterproofing of basements and other below ground structures which is:

BS 8102:2009 Revised – Code of Practice for the Protection of Below Ground Structures Against Water From the Ground.

British Standard 8102 was originally published in 1990 , when it superseded the earlier Code of Practice for Basement Waterproofing CP102:1973. The new BS 8102:2009 version is a complete revision and update of the earlier codes of practice and standards. The principle changes include considerable additional factors, information and considerations which are important when designing, specifying and constructing below ground structures. This includes:

  • The increase in deep basement construction in congested urban areas (deep is now clearly defined as meaning more than one storey below the ground level).
  • The increase in the provision of residential basements for new homes and residential developments in the UK.
  • Updated information as a result of the continuing development and use of new materials and systems for successfully waterproofing basements.

British Standard BS 8102:2009 defines the alternative basement waterproofing solutions available as including the use of:

  • Waterproof barrier materials that are applied to the surface of the structure (Defined in BS 8102: 2009 as Type A: Barrier Protection).
  • Integrally watertight design and construction (Defined in BS 8102: 2009 as Type B: Structurally Integral Protection).
  • Drained internal cavity construction, with or without sump and pump (Defined in BS 8102: 2009 as Type C: Drained Protection).

This new British Standard also now specifically recommends that a waterproofing specialist should be included as part of the project design team and that this Waterproofing Specialist should be:

  • Suitably experienced in the relevant waterproofing technologies for the type of structure.
  • Capable of devising alternative waterproofing solutions that can accommodate the relevant project's requirements and constraints.
  • Able to provide the rest of the design team with the relevant waterproofing design and construction criteria and considerations, so that this information and guidance can assist and influence the design, installation and future maintenance requirements of the structure both technically and also practically on site.
