Professional Basement Waterproofing at the BS8102 Standard

There are many companies in the UK who “do basements”, however, whether they are technically competent and experienced in basement waterproofing is another question altogether.

Pure Basement Systems offer you several assurances as to our suitability to competently undertake your basement waterproofing project.

Experience & Training

Our surveyor and managing director, Michael Foster CSRT CSSW MIWSc Dip Surv has over 25 years industry experience. Michael is also CSSW (certificated surveyor in structural waterproofing) qualified which ensures you will receive competent, professional advice from him regarding your project.

Additionally, our experienced installation team have been trained by industry leading manufacturers including John Newton & co, Basement Systems INC and Wykamol in the technical installation of the waterproofing systems we specify.

British Standard Code of Practice

Basement waterproofing systems should be designed and installed in accordance with British Standard Code of Practice BS 8102: 2009.

BS 8102 “code of practice for protection of below ground structures against water from the ground” provides a guiding framework for professional waterproofing design, installation and system maintenance.

Fundamentally, your chosen waterproofing contractor should understand, in detail, issues identified in BS 8102. They should be accredited by at least one waterproofing product supplier and have a suitable guarantee to offer you for your installation.

At Pure Basement Systems, we use the British Standard document as a guiding framework to give you the desired results for your basement project.
