Rising Damp?

Rising damp is moisture entering the property from the ground up the walls using capillary action. Depending on the age of your property your damp proof course will prevent moisture rising up the walls but older properties often do not have a DPC. A damp proof course in a newer property can fail allowing moisture to bypass the barrier.

Rising damp can cause significant issues to a building. The visible signs of spoiled internal decorations mask a bigger issue including replacing plaster in the affected area and structural timber decay. Floor joists are often affected leading to a costly repair.

Does your property suffer from rising damp? Does the wall feel damp to the touch up to one metre from ground level? Is there visible staining on the external brickwork or interior plaster?

What is the cause of rising damp?

Rising damp is often confused with the far more common penetrating damp as the signs can be similar. This form of damp is caused by water drawing up the walls using capillary action.

When the water evaporates it leaves a salt residue. This salt is found in the ground water that is drawing up the wall and is a key indicator of a rising damp issue. The damp can typically rise to 1 metre in height but we have encountered instances where it was much higher.

The residual salts on the surface can draw moisture leaving the wall feeling damp to the touch.

Rising damp treatment

RH Preservation can provide a range of treatments for rising damp including:

Triton DryZone

Safeguard DryRod

A chemical damp proof course is the first stage, depending on individual circumstances we will install a membrane and replace affected plasterwork with products fit for purpose. We will repair once and the rising damp will not return to that area.

We back up all of our work with an extensive guarantee and in the unlikely event a problem did occur we would return to fix it.
