Rising damp and how to cure it.
In most external walls the foundations are well below ground
level and the lowest part of the wall will often be in
hydraulic contact with ground having a high water content
and the wall materials will usually be finer-pored than the
soils and will draw water from the soil to attain relatively
high water contents.
Water rises up the wall by capillary action and as there is
virtually no evaporation below ground level then the water
content of the wall at just below ground level can be close
to saturation and if there is no damp-proof course( or the
existing d.p.c. is defective ) then water will rise up the
brickwork by capillary action.
This damp can rise to height of around one metre but it can
vary due to evaporation from the wall (inside and outside)
and the rate of water uptake from the ground.
There are various ways to control rising damp but one of the
most popular methods, especially in the Forest of Dean, is
to inject a chemical damp-proof course through pre-drilled
holes into the walls and this is intended to form a
water-proof barrier to water rising from the ground. However
this injected damp-proofing system rarely works properly on
stone built walls in the Forest as the fluid will often run
away in the voids and rubble in-fill of stone walls. Even in
brick walls pressure injected damp-proofing systems also
have a poor track record as they do not form an impermeable
damp-proof course because of a process known as ‘viscous
fingering’ where the injected fluid fingers through the
brickwork to find the path of least resistance and this
leaves sections of brickwork which are left unprotected and
therefore still subject to water rising from the ground.
However there is an effective system of controlling rising
damp in stone or brick built houses and cottages in the
Forest of Dean. Freezteq is a frozen damp-proofing system
where ice sticks of damp-proofing fluid are inserted
directly into mortar joints. These then gradually melt and
saturate the wall with the slow diffusion process ensuring
that all the pores and fissures within the wall are lined
with the damp-proofing solution.
