What is Basement Waterproofing and what is involved?
Basement Waterproofing and Tanking is an essential task for homeowners looking to protect their property from water ingress and dampness. It forms an important aspect of home maintenance that can help prevent costly water damage and keep your home safe and dry.
It keeps your home dry and structure sound
Water damage can promote mould growth and weaken the foundations of your property. Professional management ensures that the basement is properly sealed whilst managing the water flow around your structure. Providing a good drainage system for any water that does manage to enter the basement is important.
We follow British Standard 8102
British Standard 8102 (BS 8102) is a code of practice which provides guidance on the design and construction of below-ground structures. The standard sets out recommendations for the waterproofing of basements and provides guidance on the selection of appropriate waterproofing systems. It defines three types: Type A (barrier or tanking), Type B (structurally integral protection) and Type C (drained cavity). Our CSSW-qualified surveyors specify the right type, or combination, for your structure.
A comprehensive solution
A combination of strategies, including proper ground levels, drains or exterior waterproofing will ensure your under-ground structure provides long-term integrity. Our professional service assesses your specific situation and recommends the best solutions for your needs.

I am extremely pleased with the work and service from start to finish. Having the guys in and started within 2 weeks of my initial enquiry was very impressive. John and Shaun were knowledgeable and friendly and worked very quickly to ensure minimal disruption. Gavin kept me updated throughout and they always asked before carrying out additional works.
