Rising Damp Treatments

Control Rising Damp

Rising damp can occur in the ground floor of properties. If left untreated the
plaster can become contaminated and any timbers in close contact with the damp
walls can develop wet or dry rot infections and infestations of beetles which thrive
in a damp environment. It can also exacerbate any surface condensation issues
that the property may have.
The main cause of rising dampness due to age as earlier methods do fail over
time. Rising dampness can also be caused by high external ground level, new
construction where the damp proof course has been omitted, or incorrect replastering.

Effective Control Methods

To combat rising damp we drill into the wall of the property and inject Silicone cream or a silicone solution into the holes drilled.

We will then re-render the exposed walls to specification incorporating Sovereign Rendermix.
