Basement waterproofing
of Grade II Listed building in Gloucester
by Protectahome
Pillar and Lucy
House is a Grade II Listed building set within the Gloucester Quays
development in the historical city of Gloucester. Part of a huge £400m
redevelopment scheme, Gloucester Quays occupies 25 hectares of industrial
land on the canal corridor. Pillar and Lucy House, a former warehouse, is
located next to the canal and required a robust basement waterproofing
installation to provide dry habitable accommodation for commercial use.
A quality
basement waterproofing system was designed and installed to meet the
specific site requirements and comply with the developer's programme of
work. A drained cavity drain membrane method of waterproofing was
selected, giving particular consideration to the impact on the structure
and the reversibility of the process.
A combination of 8mm and 20mm cavity drain membranes were applied to the
walls and floors. The membrane installation was supported with a series of
perimeter drainage channels linked back to specially formed sump chambers.
Each sump chamber contained two high capacity sump pumps controlled by a
sophisticated electronic panel with battery back up. The panel allowed for
sequential pumping, duty assist, burst testing and detailed monitoring of
the pumps. It also incorporated an audible high water alarm as well as a
speech and text dialler. Directly employed staff completed the work and
the client benefitted from a long term guarantee and guarantee protection
insurance. The design was also covered by professional indemnity insurance.
