RISING DAMP TREATMENT
Damp proofing is a term referring to the process of applying protective barriers to the brickwork of properties preventing moisture from making its way to the interior of the property. One of the most common types of damp problems found in the home is rising damp.
Rising damp can be found to interior and exterior walls to ground level in properties, it is not only unsightly but can also trigger further problems within the property if left untreated, nearby timbers can be at high risk of wet rot & dry rot and condensations levels can increased due to the hydroscopic ground salts it carries along with it.
Typical causes of rising damp:
- Complete absence of damp proof course from construction of property
- Break down of existing damp proof course due to age or poor installation
- Incorrect method of re-plastering
- Bridging, when external ground level is higher than the internal level
Detecting and identifying rising damp:
Our surveyors have years of experience in diagnosing the cause of all damp problems, firstly we will identify all problem areas and go about multiple checks to determine the first cause of the damp. We will then test walls for the amount of damp they are holding and offer our advice and solutions to the customer.
How rising damp gets into the home:
The way in which rising damp works its way into ground level rooms of properties is through an action known as capillary. The moisture in the ground below the properties foundations is drawn up through the masonry, past the broken down or absent damp course into the home usually no higher than roughly a metre depending of severity. The ground moisture which is drawn up carries with it mineral salts that are sometimes visible on the plaster as the moisture evaporates into the home, this is what typically causes the spoiling of the decorative surface and break down of internal plaster.
To put it quite simply the wall of the property acts almost like a sponge as it soaks up the moisture from below.
The solutions for treatment of rising damp have come a long way with modern methods which allow us to eradicate the problem for good. After removing the existing contaminated plaster a new remedial Dry-Zone damp proof course will be injected into the mortar of the masonry, this cream like chemical solution disperses along the mortar line fusing to create a brand new damp course stopping any rising damp from passing through. The next step in or solution is re-plaster the walls using a chemical salt retardant agent or a damp proof membrane which prevents any salts remaining in the brickwork from contaminating the new plaster.
