Case studies

Delta Registered Installers, Oaks Damp Proofing having previously undertaken work for the client were commissioned to design and install a Cavity Drain Waterproofing system that would meet BS8102:2009 the British Standard for the protection of structures against water from the ground, Grade 3 (no dampness or water penetration acceptable) to the cellar area of The Blonde Hedgehog.

Delta Registered Installers, Cannon Clarke were commissioned to design and install a guaranteed waterproofing solution for Po Na Na, a Moroccan-themed nightclub venue situated in a vaulted cellar in Bath’s popular Parade area.

The vault was suffering high volumes of water ingress during rainfall due to the road above.

Delta and MemTech Registered Installers, Renlon were called upon to offer a solution to this property, taking into consideration the proximity of The New River and the risk from ground gases. The proposed remedial strategy to be adopted at the site was one of managing the pathway between the source of contamination and the critical receptors on-site.

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.
