The Problem:
Damp proofing
prevents rising damp, which is the movement of moisture up a wall by
capillary action. Moisture will penetrate when there is no damp
proof course, or it is defective. Moisture can also bypass the damp
proof course when bridging occurs, that is, the course is overlapped
by internal or external plaster, render or the external ground
level.
The moisture brings with it natural salts in solution which rise
with the moisture up the wall and into the plaster. As the moisture
evaporates away the salts accumulate. These salts are hygroscopic,
that is, they absorb atmospheric moisture, and therefore make walls
remain damp even after the rising damp itself is stopped. This is
why it is generally necessary to replace some plaster as part of
damp proofing treatment.
The Symptoms:
The symptom that clearly identifies rising damp is the “tidemark”
effect. It leads to soft plaster and causes permanent damage to
decorations.
Our Solutions:
You can rely on our experienced surveyors to spot the exact problem
causing rising damp in your home, and recommend the optimum
solution. We offer a range of different systems that inject a new
chemical damp proof course and we recommend the one best suited
for the construction of your property. The work will be completed by
our own staff, not by sub-contractors.
