Damp Proofing
We can help with a range of damp proofing requirements, including issues caused by rising damp, penetrating damp, for both internal and external walls.

Rising Damp
Rising damp is caused by having ground level higher than a damp proof course (DPC) line (this usually rises around a metre high). To solve this, the height of ground level should be lowered, or if this is not possible, a section taken away and membrane applied higher than the ground height passing DPC inside and out. If the DPC level is correct and still rising this can be due to corroded DPC, or even none, as houses built before 1873 did not have damp proof courses. In this case an injection system will be needed on the mortar joint to prevent water ingress.
Penetrating Damp
Penetrating damp is a problem caused by external rendering coats turning hollow and finally blown due to water ingress, which gets inside the render coats from the slightest crack. The damage can be worst in winter as the water freezes and expands and opens the wound more. Other causes can be broken guttering, rotten edging felt, even pipe work inside. Damage inside must be hacked back and aired out ,the same applies to outside then totally redone in new finish coats dependent on how severe damage is. If there is no access to outside wall then a Oldroyd damp proof course membrane system will be applied


Condensation & Mould
Mould is usually mistaken for damp ingress. Mould is created by condensation, which is created by cold surfaces meeting warm air. To cure this you must create a barrier between the two, to stop the temperatures meeting. To solve this issue, we can apply a thermal application which prevents the issue occurring.
