Basement waterproofing in Houses of Parliament

Basement waterproofing in Houses of Parliament

INTRODUCTION

MacLennan was employed by Shaca to come up with a guaranteed scheme for a new build basement at the houses of parliament, they were engaged to carry out a site survey and to specify the necessary work to provide a guaranteed system.

METHODOLOGY

The MacLennan team designed an external waterproofing system with an internal cavity drain and a polyurea roofing system to guarantee it was waterproofed to a high standard. An 8mm ventilated cavity membrane was installed from floor to ceiling, then a lime inhibitor was applied to the floor area followed by a 20mm membrane and drainage system. The roof deck was coated with MacLennan Polyprufe primer and polyurea, then a drainage membrane was applied on top.

RESULT

The final outcome ensured a waterproof basement that complies with BS8102 2009 and was guaranteed against water ingress. Benefits: The whole contract was designed and carried out by MacLennan under their insurance cover and PI. The whole system was guaranteed by MacLennan.
