Rising damp

Rising damp isn’t always visible: it’s often hidden by decoration. A survey finds it; a damp-proof course treats it.

CH 02 · The problem and the treatment

What it is, and how we treat it.

Rising damp is not always visible. It’s often hidden by decoration.

We treat it with a cream-based chemical damp-proof course, injected into small holes at low pressure, to BS 6576.

Salt-contaminated plaster usually needs renewing as well.
