Basement Waterproofing – Wentworth, Surrey

Basement Waterproofing Wentworth Surrey


This large prestigious new-build property in Wentworth Surrey had a very large basement area which needed to be waterproofed to meet BS8102 requirements (the British Basement Waterproofing 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, Basement Waterproofing Standard BS8102 tells the designer to expect a head of water against the structure. In addition, BS8102 requires that all Basement waterproofing is maintainable and repairable.

The Maclennan Basement Waterproofing Design Team worked closely with the client. After consultation the Macleannan Basement Waterproofing Designers put forward a comprehensive basement waterproofing system design, that meet with all of the requirements for this prestigious new build basement.

Newton Specialist Basement Contractor 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.

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.

1. Newton System 500 is easily and quickly repaired and maintained.
2. 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.
3. 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 MacLennan
All work was carrried out with in budget and with in the agreed time constraints, the property is completely protected against water ingress.
