A Prestigious New-Build Property in Surrey

Image 1This large new-build property in Surrey had a very large basement area which needed to be waterproofed to meet BS 8102 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, BS 8102 tells the designer to expect a head of water against the structure. In addition, BS 8102 requires that all waterproofing is maintainable and repairable.

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 BS 8102. Newton 508 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 Newton Titan-Pro pumping system.


  • Newton System 500 is easily and quickly repaired and maintained.
  • The complete system is guaranteed for a full 20 years by MaclennanUK. If the system is inspected and serviced annually the guarantee can be extended every 10 years for a further 10-year period.
  • The system is very fast to install and there is no drying period.

“Maclennan worked with Ali Galvin Homes to come up with a risk-free waterproofing strategy, to waterproof the very impressive and luxurious property that they were constructing. Newton System 500 is the best system available to waterproofing professionals and was ideal for this project” – Ian MaclennanUK
