The Safest Form of Waterproofing Available, and One of the Easiest to Understand and Specify
A guaranteed dry basement or cellar is just four easy steps away. The image below shows the system Abacus uses to a new-build concrete construction but the system is equally effective when applied to existing properties and even historical properties
STEP ONE
Wall Membrane
Choose an appropriate wall membrane to suit your wall finish. In this example, the membrane has been chosen for the walls and is shown with both independent metal frame dry-lining and concrete block wall coverings.
STEP TWO
Drainage System
Choose your preferred method of water collection. Here the solution is sat above the slab adjacent to a spacer of 50mm of closed cell insulation
STEP THREE
Pump Systems and Pumps
Choose the correct method of removal of the water. A special sump system collects water from the drainage system via two connections. The pumps (not shown) would be chosen depending on factors such as the pumping head and the type of water collected.
STEP FOUR
Floor Membrane
Choose the correct floor membrane for your finishes and floor loadings. The solution here is shown with a 65mm screed above.
Unlike conventional ‘tanking’, this solution is not attempting the impossible and trying to hold water back, but places designed and maintainable depressurisation voids at the known weaknesses in the structure so that ingressing water is simply captured and diverted out of the property. |
