Delta Membrane Systems Ltd

This large new-build structure required to be waterproofed to meet BS 8102:2009, the British Standard for the Protection of Structures against Water from the Ground requirements. As it is not possible to determine the amount of potential water pressure surrounding the structure, BS 8102:2009 states the waterproofing designer should expect a head of water against the structure at some stage during the structure’s service life.

Vaults are a common feature of 18th and 19th century buildings in Bath. Originally built to support the cobbled streets above and were a constructional response to the precipitous topography that surrounds Bath, in order to provide a level site. Many of the vaults within historic Bath suffer with water ingress and damp related problems. Incorporating best practice guidance - Type C Waterproofing Systems (BS 8102: 2009) a Type C System was used to keep this historic vault watertight and dry.

When specifying the most appropriate method of waterproofing for a new-build basement it is advisable to follow the recommendations within BS 8102:2009 ‘Code of Practice for Protection of Below Ground Structures Against Water from the Ground’. The standard advises on the types of waterproofing available and confirms the performance grade to be achieved. This project required Grade 3 protection – no dampness or water penetration acceptable.

An innovative and comprehensive waterproofing solution was required to facilitate a £18m state of the art hotel and with a double story basement in Englefield Green, near Windsor. The hotel will offer exceptional overnight breaks, award-winning dining & an exclusive spa facility once completed.
