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 were commissioned to design and install a Cavity Drain Waterproofing System. Newton System 500 was deemed the best range of products for the project as it provides a maintainable waterproofing solution – and thus meets the requirements of BS8102. Cavity Drain Membrane was applied to all internal walls, and ingressing water was collected into the Basedrain channels throughout the perimeters of the wall/floor junction and pumped out to safe drainage using the Titan Pro pumping system.
