Case studies

The scope of this project was incredibly interesting. The owners sought to create a subterranean space which had the look and feel of a magical ‘Hobbit Home’ as if created by J. R. R. Tolkien himself.

Delta Registered Installers, Renlon Limited were commissioned to create a waterproofing design for a newly constructed subterranean House, buried into a bank in heart of the Rother Valley. 

Celtic Manor is a 5-star resort is set in more than 2000 acres of panoramic parkland at the gateway to Wales.

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, further, BS 8102:2099 states that all waterproofing systems should easily be maintainable and repairable.

Delta Registered Installers, Premier Preservations, were approached to offer a waterproofing design and system to a basement, to ensure the vaults – located under the entire footprint of the property were protected from water ingress.

The scope of the works included a full waterproofing system for the basement which was a mixture of vaulted ceilings of solid, lath and plaster with external walls partly below exterior ground and approximately 500mm thick. 

The project was split into 2 phases.  Phase 1, waterproofing the exiting basement and Phase 2, retrofit extension to the existing basement to create a luxurious multiuse living area.

Due to the partially retaining nature of the structure, the project required a combination of Type B and C waterproofing systems to ensure a Grade 3 habitable environment.
