Waterproofing this historic London landmark - external waterproofing with Newton 403 HydroBond, internal waterproofing with Newton System 500, installed by Newton Specialist Basement Contractor MacLennanUK.
Combined Waterproofing System, Internal and External Protection
Newton Waterproofing were delighted to return for this project at the prestigious Houses of Parliament in London, a landmark that has dominated London’s skyline for over 150 years. Newton Specialist Basement Contractor MacLennan Waterproofing was approached to specify a guaranteed waterproofing solution for the new-build basement.
After reviewing the technical drawings, MacLennan decided to bring the job to Newton, whose product range was perfectly suited to the project requirements. Newton and MacLennan are both privileged to be the companies chosen to share in securing the future of the Palace of Westminster.
This complex project required the design and installation of an external waterproofing system, an internal cavity drain system, and a polyurea roofing system to ensure a high standard of waterproofing.
Externally, Newton’s innovative ‘Type A’ 403 HydroBond membrane was applied extensively to ensure the necessary waterproofing around the basement, whilst internally, Newton 508 and Newton 520 membranes were both applied from floor to ceiling as part of Newton’s complete System 500 cavity drainage solution. With the finished structure in place, the waterproofing was finally completed by the application of both a polyurea coating and further drainage membrane to the roof deck of the basement.
The 1m x 20m rolls of 403 HydroBond are quick and easy to apply against the wall shuttering.
The self-healing characteristics of 403 HydroBond allows penetrations through the membrane, whilst still maintaining a watertight seal around the structure.
Newton Waterproofing were delighted to return for this project at the prestigious Houses of Parliament in London, a landmark that has dominated London’s skyline for over 150 years.
With a waterproof basement fully compliant with the requirements of BS 8102:2009, coupled with guaranteed protection against water ingress, this newly completed, large basement area, situated directly next to the River Thames, provides a durable and well established waterproofing solution, utilising multiple Newton Systems to great effect.
With many historic and listed buildings not benefiting from modern forms of protection, they are often subject to the detrimental effects of damp. How do you therefore maintain structural and aesthetic integrity, whilst still achieving the desired effect?
