Cellar conversion Colchester
If a structure is completely underground or partly earth-retaining, there is a very high chance of it being affected by hydrostatic pressure of moisture (lateral penetration). If you do not live in the cellar, it doesn’t really pose a problem. However, if you will be using it as additional living space various options should be considered in order to transform the cellar into habitable room. Our surveyor will be pleased to carry out an inspection and provide a detailed report and estimate on the most suitable method for cellar conversion.
BS8102:2009 is the British Standard for waterproofing below-ground structures. Working to this standard ensures consistently high quality and also reduces the possibility of waterproofing systems failing. There are three types of protection available.
Cementitious tanking is a multi-render coating which is applied directly to the walls and is the most traditional method of cellar conversion that includes a waterproofing agent. It will only work if the substrate is in good condition. Any movement or cracks in the substrate could cause failure.
Cavity Drainage Membrane
The modern alternative is to apply a plastic dimpled membrane with drainage channels, a sump chamber and pump. It cannot withstand water pressure but is able to provide a dry usable room by diverting the water away from it. The walls can then be finished in a render or lined with insulated plasterboard and skimmed with plaster to give a smooth finish on the cellar walls.
Dry Lining System (without drainage)
Instead of using a full drainage system you can install a ventilated dry lining system to the cellar to provide protection from damp. A plastic membrane can also be used and will give the same results. However, this method will not be recommended where standing water is present as it will not resist water pressure and cannot be guaranteed waterproof.
Whichever method is used for your cellar conversion, two important factors should be considered when making the space habitable. Mechanical ventilation (if no windows exist) and sufficient heating.
Waterproofing to Floors
In some cellars our experienced team will recommend Epoxy resin as a suitable solution for tanking solid damp floors, which are in a sound structural condition. Usually, two coats will provide enough of a durable waterproof membrane and will tolerate normal mechanical wear.
