Basement waterproofing regulations

Ask a question

When it comes to basement waterproofing or basement conversion regulations, the BS 8102:2009 from the British Standards Institute is in essence the ‘bible’ for providing a code of practise for the protection of below ground structures against water from the ground.

In summary, it is a design document  providing basement waterproofing regulation guidelines with the purpose of providing ‘best practise’ towards the various basement, cellar or underground waterproofing methods and outlines the use of:

  • Waterproof barrier materials that are applied to the surface of the structure
  • Integrally watertight design and construction
  • Drained internal cavity construction, with or without sump and pump.

Although not UK law, failure to ahere to BS 8102 standards may result with the basement waterproofing or basement conversion contractor having a difficult time in a court of law in the event of litigation following a cellar or basement waterproofing failure.

Basement waterproofing regulation types

British Standard BS 8102:2009 defines the alternative basement waterproofing systems available and describes in detail the 3 different approaches to waterproofing. They include:

  • Type A Waterproofing – Barrier Protection (Tanking)
    External, Sandwiched or Internal
  • Type B Waterproofing – Structurally Integral Protection
    Usually to the relevant British Standard and of reinforced concrete structure
  • Type C Waterproofing – Drained Protection
    Cavity Drain Membranes and Construction Drained Cavities

In summary, any basement or cellar waterproofing specialist that aheres to the guidelines (and we strongly recommend that you do ensure that the waterproofing specialist does ahere to the guidelines) will breakdown the types of waterproofing options available to you and recommend the the most appropriate options depending on the identified water issue (if any) and what you intend to use the underground space for.

Things to note within the basement waterproofing regulations

Before any work can commence, all your basement waterproofing or basement conversion plans need to be submitted in full to your local authority so they can assess them to make sure they fall under the regulations of BS 8102:2009.

Also within section 4.2 for the new basement waterproofing regulation, the code recommends “A waterproofing specialist should be included as part of any underground structural waterproofing design plans so that an integrated waterproofing solution is created. The waterproofing specialist should:

  • "Be suitably experienced  
  • "Be capable of devising solutions that accommodate the various project restraints and needs  
  • "Provide the design team with information and guidance that assists and influences the design, installation and future maintenance of the waterproofed structure” 

It goes on to say “…The waterproofing specialist could be a manufacturer or material supplier, provided that the manufacturer/supplier has the relevant expertise”
