Damp Proofing/ Penetrating damp

Damp Proofing

Is the term used for fixing rising damp in a property.

We can give a free in depth survey of your property using moisture meters and relative humidity meters, to determine where your damp is coming from and the best methods to cure the problem.

Not every damp patch in a house is down to rising damp it can be a number of different factors so a proper survey is very important to avoid unnecessary work and expense.

Tell tale signs of rising damp are bulging blown plaster work that is soft to the touch, peeling wallpaper around floor level and paint discolouration.

If rising damp is the issue then the old plaster is removed, then a new damp proof course (DPC) is injected by drilling a line of 10mm holes and injecting Kingfisher dri-wall cream into them inside and outside the property if possible. Then the wall is replastered using a 3-1 sand and cement base coat with a waterproof additive added to it Kingfisher K-X11. This is then replastered with normal plaster and you can paint it as normal.
