The owners of this stylish property near Guildford in Surrey were looking to expand the living area without having to move from the area. Due to planning constraints they were not able to extend their house out and so decided to create an entirely new living space in the form of a basement
MacLennan were contacted by Adams Architecture who we regularly work with on Projects to provide a waterproofing design, for this large detached property in Hampstead. The design was for a Cavity Drain System to the main basement and MacLennan’s own Polyprufe Deck waterproofing system to the 500sqm Terrace area.
This large new-build property in Surrey had a very large basement area which needed to be waterproofed to meet BS8102 requirements, the British Standard for the Protection of Structures Against Water From the Ground.
Because it is not possible to determine the amount of potential water pressure surrounding a structure, BS8102 tells the designer to expect a head of water against the structure. In addition, BS8102 requires that all waterproofing is maintainable and repairable.
MacLennan was employed by Cardy construction to provide a suitable waterproofing solution for two refurbishments with new build basements and 1 new build property, MacLennan arranged a site visit and surveyed the area to provide an accurate specification for the new build cavity drain basement waterproofing system.
The basement will house the gym, swimming pool, garaging , plant rooms etc. The waterproofing was the most critical item in the design and installation. MacLennan supplied design expertise and detailed all aspects of the waterproofing with the Architect, engineer and contractor.
