Damp proofing was on the agenda again as heavy rain being absorbed by the ground takes its toll on Leeds properties.

DPR were called to a semi-detached property in Oakwood which showed the affects of damp on various parts of the house.

In determining the extent of the problem, highly accurate electronic Protimeter readings were taken on the wall which showed evidence of dampness. This was attributed to rising damp in the wall.

To prep the area for treatment, DPR Leeds removed the original wall plaster where the moisture levels had caused the most damage.

In treating the rising damp we injected a tri-gel chemical mortar and our vertical DPR plasterbase membrane system into the wall. To prevent further attacks from dampness due to the hygroscopic salts deposited in the original plasters, we then sealed the wall with specialist plaster consisting of BS 1200 Portland cement mix, chemical waterproofing agents and plasticiser.

As we are receiving more and more calls to rectify rising damp problems we thought we would answer a question we frequently get asked, which is; ‘Why can damp affect internal walls between my rooms?’

The answer; Well if you think about it logically, your internal masonry walls are as much in contact with the ground (previously open land) as the outside walls are, and therefore have as much ability, if not more, to allow the vertical passage of moisture.
