In a modern building, a watertight damp proof course is placed in block work at a low level, which serves as a barrier against upwardly moving ground dampness. In earlier times, rising ground dampness and its effects were not well known, and with the exception of very far sighted practice, old stone and brick walls were not provided with a damp-proof course.
The end result is that the affected walls are permanently damp at a low-level, being visibly affected in the form of damp staining of decorations, breakdown of plaster, deterioration of skirting timbers, window panelling timbers and doorframes.
We provide the two main systems by which rising damp is eliminated:
- Siliconate Or Liquid Chemicure Injection Damp Proof Course
- Electro-Osmotic Damp-Proof System.
However, prior to committing to remedial damp proof treatments, with associated disruption and expenditure, it is essential that the actual cause of low-level dampness is established. Other factors could contribute; such as pipe leaks, incorrect level of damp proof course, defective floor, or high external ground levels.
If a building does indeed have rising damp, you would expect to see some or all of these issues:
