Combined Systems Type A and C Waterproofing Protection provides Grade 3 Habitable Environment

Combined Systems Type A and C Waterproofing Protection provides Grade 3 Habitable Environment

Newton Specialist Basement Contractor MacLennan-LSE was commissioned by the client to work with the architect to design a robust structural waterproofing scheme to achieve a Grade 3 habitable environment to this extensive new build basement project in Hampstead North London.

Methodology
MacLennan-LSE designed and installed a combination system of Type A sprayed Polyprufe and Type C drained cavity protection Newton System 500 to waterproof the new build basement. The internal system involved “curtain hanging” the Newton 508 membrane to all internal 250mm thick reinforced concrete retaining walls as a means of diverting any water that was to enter through the construction joints to the wall floor junction.

At the wall floor junction, Newton Basedrain was installed within a layer of “closed cell insulation” with another layer of Newton 508 installed on top of the insulation layer. With the layers in situ, a 65mm screed was installed with underfloor heating embedded prior to the wall finishes (independent dry lining system) being installed. With the Newton 508 membrane raised up higher than the top of the Basedrain, any water ingression was then displaced through the weight of the screed back to the Basedrain for removal to dual sump and pump systems.

Result
MacLennan-LSE was able to install the combined system in the middle of winter with adverse weather conditions not effecting the time of installation of the system as is often the case with external waterproofing applications.

Benefits
• BBA approved Newton System 500 was able to be designed, installed and guaranteed as a package by MacLennan-LSE.
• As the system was installed by MacLennan-LSE, they were able to take full PI on design and offer a 20 year insured backed guarantee.
• The internal system installed required minimal surface preparation and was not affected by the constraints of near zero degree temperatures that were on site
