Pittshanger Manor and Café, Ealing
4Site excavated and built the basement, lift shaft and internal structural works for the Museum. We then built the café from foundations to completing the whole envelope with a brick finish. These works were all done for the main contractor.
Cavity Drain Membrane
Cavity drain membranes tend to be our waterproofing solution of choice as we believe they provide a more effective alternative to the traditional cementitious tanking systems. Delta cavity drain membranes utilise the innovative design process which allows water to penetrate the structure but once inside, the water is held within the air gap and then diverted to a suitable drainage point.
This waterproofing system avoids the build-up of pressure against the wall which can be found with cementitious tanking. The air gap means that the building can breathe and dry out, making it much more effective for waterproofing solutions in many scenarios.
This basement waterproofing system avoids the build-up of pressure against the basement wall which is found with cementitious tanking. The maintenance of the air gap means that the building can breathe and dry out, a much more effective solution for basement waterproofing.
Waterproof Concrete Systems
Waterproof concrete systems are commonly used in basement waterproofing, but can be used in other areas. This traditionally goes alongside other waterproofing protection, making up part of a full waterproofing system where water-bars may be required as well as tanking and damp proof membranes.
Cementitious tanking involves applying a concrete slurry substance to the wall which acts as a barrier to the water. This waterproofing system depends on the quality of the wall that the slurry is being applied to, it will not always be an appropriate solution. As an honest waterproofing company, we will never implement a solution we don’t believe will be long-lasting and always recommend the most suitable approach.
If the walls in your property are older or have the potential for significant movement, the cementitious tanking method may not be sustainable. In addition, the build-up of water against the wall can cause problems with the brickwork over time.
Effective basement waterproofing is a vital part of basement construction when conducting a basement conversion, but is also highly recommended even if the basement is not in use. Issues with water drainage are a common problem faced with basements, leading to them remain unused. Over time, the constant damp can deteriorate the condition of the building foundations and lead to some unpleasant odours in your property and sometimes even structural damage. Basement waterproofing is required to prevent future damage and ensure this underground space in your project stands the test of time.
