Waterproofing regulations

The main regulations regarding basement waterproofing is BS 8102 2009 from the British Standards Institute (BSI.). BS 8102:2009 is a set of ‘best practise’ guidelines for all facets of structural waterproofing including;

• 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.

These guidelines are not UK law, but BS 8102:2009 should be followed any reputable waterproofing contractor.

In the waterproofing industry contractors usually categorise waterproofing into three “types” (A, B and C). This relates directly to the definitions laid out in BS 8102:2009.

Types A, B and C are as follows:

• Type A Waterproofing: Barrier Protection (Tanking)
• Type B Waterproofing: Structurally Integral Protection
• Type C Waterproofing: Drained Protection, Cavity Drain Membranes and Construction Drained Cavities

Regarding waterproofing services on offer at Peter Cox; Type A would be basement tanking, Type B would be a basement waterproofing integrated into a construction project and Type C would include the most common waterproofing work we carry out – the installation of wall waterproofing, basement floor drainage and sump pumps.

BS 8102:2009 also stipulates grades (1, 2 and 3) of waterproofing systems relating to their performance and use. 

• Grade 1: Some moisture ingress is acceptable. This would be fine for Car parks etc.
• Grade 2: No moisture ingress is acceptable but small areas of damp areas are
  tolerable. This would be fine for industrial boiler rooms, workshops etc.
• Grade 3: No dampness or water penetration is acceptable. This is when an area
  needs to be completely watertight and dry e.g. domestic basement conversions,
  offices, shops etc…

• Section 4.2 of BS 8102:2009 lays out some guidelines for anyone hiring a basement waterproofing contractor. The Guidelines recommend that a waterproofing specialist should be included as part of any underground structural waterproofing design plans and they should meet the following criteria:
• Be suitably experienced
• Be capable of devising solutions that accommodate the projects needs
• Provide information and guidance on the design, installation and future maintenance
  of the project
