Basement and cellar tanking in Chelmsford
Below-ground rooms have soil pressing against the walls, so standard damp proofing won't keep them dry. They need a waterproofing system designed for it.
Signs your cellar needs waterproofing
- Damp or wet walls and floor
- White salts or flaking paint
- A strong musty smell
- Standing water after heavy rain
The main options
Cementitious tanking is a waterproof render applied directly to the walls and floor. It suits smaller cellars used for storage.
Cavity drain membranes are fixed to the walls and floor, leaving a small gap behind them. Any water that gets through runs down behind the membrane to a drainage channel and, if needed, a sump pump. This is the usual choice if you want to turn a cellar into a usable room.
Planning a conversion?
If you want to use the cellar as a living space, the waterproofing needs to be right from the start. A survey looks at how wet the cellar gets, where the water comes from and which system suits it.
