OUR SERVICES
Capital Waterproofing are able to offer a fully project managed waterproofing service. Out team of CSSW qualified surveyors can design the waterproofing system for a new build waterproofing project or inspect and survey an existing basement structure for the retrofit or repair of the waterproofing system.
WATERPROOFING DESIGN
Our team of CSSW qualified technical surveyors can provide an integrated waterproofing design for any project. Our designs follow the requirements of the British Standard for Waterproofing, BS8102:2009, as well as the site and project design briefs. We have professional indemnity insurance (PI cover) for waterproofing design. We are experienced in designing waterproofing for new build and refurbishment projects as well as internal, external and cavity drainage waterproofing.
CAVITY DRAINAGE MEMBRANES- TYPE C WATERPROOFING
Cavity drainage membranes are studded sheets of HDPE membrane which are used to internally line the basement walls and floor. Any water that enters the structure is harmlessly diverted into a suitable drainage system whilst the internal space remains dry. Walls are then finished using a plasterboard dry lining system and often a screed finish to the floor.
EXTERNAL WATERPROOFING MEMBRANES- TYPE A BARRIERS
External waterproofing systems work by protecting the outside of a structure against water ingress. External barriers can be pre-applied to new concrete structures or post- applied to masonry or blockwork structures. External waterproofing is typically used as part of a combined waterproofing system for new build projects but can be used in isolation for areas such as car parks where an exposed concrete finish is required.
INTERNAL TANKING SYSTEMS- TYPE A
These systems involve using an impervious barrier to the inside face of the structure to physically hold water back. Our technical team can advise on the careful substrate preparation required as well as detailing for fixing points and services. For larger projects we have a specially trained spray applied waterproofing team, this means we are able to apply waterpoof tanking systems quickly and accurately.
GAS MEMBRANE INSTALLATION
Capital Waterproofing offer a design and install service for gas protection membranes for new build and refurbishment projects. Systems include gas membranes, gas and waterproof membranes for basement and retaining structures and liquid applied gas barriers.
CONCRETE REPAIR AND RESIN INJECTION
Unfortunately, errors do occur in the formation of concrete structures. Failures in basement concrete structures are often from poor concrete compaction and incorrect concrete hydration. Capital Waterproofing are able to inspect, specify and repair defective concrete construction joints, areas of honeycombed concrete or structural cracks.
LIFT SHAFT WATERPROOFING
Lift pits area usually the lowest part of the basement floor slab but receive the least attention when it comes to waterproofing design. Capital Waterproofing can effectively seal leaking lift pits against water ingress on existing flooded lifts as well as design lift pit waterproofing systems for new build projects.
BURIED ROOF AND PODIUM DECK WATERPROOFING
The waterproofing of a roof over a basement requires careful consideration. Buried roofs are often subject to extended periods of water pressure, unlike roofs above ground. Our expert technical team will advise on suitable waterproofing systems as well as drainage requirements for buried roofs and podium decks.
