Damp and damp proofing is by far, the most frequent problem encountered in the home and it is no surprise that damp proofing can become a big problem for many with our climate. Damp can be very bad for our health and cause damage to property.
All buildings are surrounded by natural moisture which is trying to get into the dry structure of the building. Building materials such as stone and brick are naturally porous and will soak up moisture like a sponge without a damp proof membrane or rising damp treatment.
When a building is constructed, rising damp treatment is normally installed in the form of a damp proof course in the walls, when this treatment does not exist or becomes damaged the most common result is rising damp.
If you have a rising damp problem you need to find an appropriate rising damp treatment as soon as possible. Often, the easiest and most reliable way to do this is to contact a specialist rising damp contractor familiar with rising damp problems who is qualified within rising damp treatments.
How to spot if you need rising damp treatment
Tell tale signs of rising damp include a “tide-mark” on the wall above skirting boards (up to 1 metre), peeling wallpaper, white efflorescent salts which have been drawn out of the brickwork by the water. Rising damp can usually be identified by the visual clues and by touch.
Typically a rising damp treatment involves repairing the existing damp proof course or installing a new one. Most commonly this is done by drilling holes in a band around the affected wall and injecting a retrofit chemical or osmotic solution or a physical damp proof membrane and then replacing any salt contaminated plasterwork.
If this plasterwork is not properly removed and replaced with specialist salt retardant plaster, the salts that are present in the plaster may continue to absorb moisture from the air and continue, even after the installation of a new retrofit damp proof course and give the appearance of dampness.
