Not all cellar areas require a full drainage system , for waterproofing the space, sometimes a tanking system will suffice .

There are 3 main situations which can arise in buildings, which may require using a tanking system.

It is important to choose the correct tanking system, our surveyors will advise.

There are a number of options for completing a tanking system.

It is vital whatever solution is selected , that, the resulting dry space has structural integrity as well as dry conditions. Our skilled surveyors can ensure that the correct option is chosen.

Cementitious coatings as tanking systems will give effective waterproofing of space.

For a satisfactory tanking system , in all cases, surface preparation is critical , even the best tanking systems will not perform properly if not applied correctly. Cracks and crevices need to be sealed to give a waterproofed area and a correct tanking system.

In cases where water ingress is moderate and the cellar area is to used for storage rather than frequent habitation we would recommend the use of a cementitious coating as the appropriate tanking system.

Properly applied to chemical suppliers recommendations, this tanking system will last for years, giving a dry area and valuable extra space for that additional storage that homes always seem to need.

Where water ingress is significant or hydrostatic pressure is likely to be high we recommend the use of a drained cavity system ( see our section on cellar conversion ) This will give a truly dry solution, suitable for daily habitation.
