How to waterproof a basement

Waterproofing of basements is a specialised service that requires appreciation of the problems which can be encountered.

Before waterproofing a basement, consideration should be given to the type of construction, the use of the building, the soil topography around the property and the ability to repair the basement in the future.

British Standards

The British Standard BS8102 also advises that a Waterproofing Design Specialist is involved at the design stage of new basements to help ensure that the effective waterproofing is considered during the design and ensure the provision of dry basements.

Kenwood Plc are qualified Waterproof Design Specialists, utilising the extensive knowledge of their Chartered Engineers and Consultants with the specialism of 30 years waterproofing basements.
