Summary

• 

  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.

• 

  The self-healing characteristics of 403 HydroBond allows penetrations through the membrane, whilst still maintaining a watertight seal around the structure.

• 

  The 1m x 20m rolls of 403 HydroBond are quick and easy to apply against the wall shuttering.

Waterproofing this historic London landmark – external waterproofing with Newton 403 HydroBond, internal waterproofing with Newton System 500. Installed by Newton Specialist Basement Contractor MacLennan UK.

The Project

Newton Waterproofing felt delighted to return to the prestigious Houses of Parliament in London, a landmark that has dominated the city’s skyline for over 150 years. The project team approached Newton Specialist Basement Contractor MacLennan Waterproofing to specify a guaranteed waterproofing solution for the new-build basement.

After reviewing the technical drawings, MacLennan brought the project to Newton, whose product range perfectly matched the project requirements. Indeed, Newton and MacLennan take pride in helping to secure the future of the Palace of Westminster.

The Soltuion

Explicitly, this complex project required the design and installation of an external waterproofing system and an internal cavity drain system. A polyurea roofing system was also used 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 Result

The newly completed basement fully complies with BS 8102:2009, providing guaranteed protection against water ingress. Despite its location directly next to the River Thames, the team provided the large basement with a durable waterproofing solution.
