DIY Rising Damp Control (Stop Rising Damp)
Stop Rising Damp
THE MOST COST EFFECTIVE, DIY, METHOD TO STOP RISING DAMP DEAD.
DO NOT APPLY ON FRESH MORTAR OR CONCRETE, AS THIS PRODUCT REACTS WITH THE CEMENT, AND STOPS THE CURING.

ANY MATERIAL APPLIED ON THE SURFACE, IS MERELY A COSMETIC, SHORT TERM SOLUTIONS. MANY SUCH PRODUCTS ARE USED BY SELLERS WHO WANT TO HIDE DAMP PROBLEMS IN THEIR HOUSES.
Provides a 30 year Damp Proof Course. This material, SR87, reacts with the cement in the plaster, or the mortar, bonds with the mortar, and effecttively stops rising damp.
1. Boudary walls do not have DPC by law (as the plastic sheeting, would separate the wall from the foundation, and create a weak point).
2. Apply 500 ml of SR87, per running m of wall, to stop rising damp. Easy DIY application.
At a retail price of about R 172 / L (in a 5 L tin); the price to stop rising damp will be about R 86,00 / linear m, more materials only. The time it takes to drill 27 holes, using a jig is about 60 minutes - at a labout rate of about R 50 / hour, the estimated cost per linear m, will be R 50,00.
3. Hire a professional drilling machine, get one of our special jigs to help make neat and fast holes at 45 degress along the bottom of the bounday wall, or house wall. Drill 6 holes per brick (about 70 mm apart, in two staggered row, about half a brick apart in height) along the bottom of the wall, about 1 brick above the paving / floor level. Use a 260 mm drill bit. Suck the dust out. with a vacuum cleaner Pour SR87 into each hole., using a small plastic bottle with a thin nipple. BY APPLYING IN TWO ROWS ABOVE THE PAVING LINE, THIS LIQUID WILL RUN DOWN THE CLAY BRICKS AND CHEMICALLY BOND WITH THE LAYER OF MORTAR JUST ABOVE THE PAVING LINE.
For cement stock bricks, the liquid will react with the entire brick, and the whole row of brick will become a water barrier. A chemical Damp Proof Course (DPC). In the case of cement bricks, its probably better to apply 4 x times per hole. Until the brick becomes saturated, and no more liquid goes in.
CONTRACTORS AND HOME OWNERS MUST MAKE SURE THAT ENOUGH LIQUID IS POURED TO CREATE A BARRIER WITHOUT GAPS, THROUGH WHICH HUMIDITY COULD RISE UP.
To get 500 ml / linear m, apply 3 times to each hole. For a single wall.
Boundary walls should be treated on both sides of the wall. House walls may have to be drilled on the outside, the inside or both, depending where the rising damp appears.
Each hole has a volume of about 6 ml. 1 linear m of wall has 4,5 bricks; Drilling 6 holes / brick, gives 27 holes / linear m of wall. By applying 3 times x 6 ml, you are pouring 18 ml of liquid per hole, x 27 holes in 1 linear m, you use about 486 ml / linear m.
The time for the liquid to be absorbed into the wall, depends on the type of brick.
Clay stock brick takes about 5 minutes to absorb 18 ml;
Hard Clay Face brick takes about 1 hour; As the liquid does not react with the clay brick, it will run down through the brick and bond to the layer of cement mortar below the brick. This layer of cement mortar will become water - repellent, a chemical DPC (Damp Proof Course)
Cement stock brick takes about 1 hour to absorb 18 ml (Note that cement stock bricks react with the SR87 liquid, as it absorbs it; hence it takes longer to absorb. The cement stock brick becomes water repellent.
Humidity and moisture in the bricks will not stop the liquid from being absorbed. The maximum water content that a brick will absorb is about 14% by weight. This has been checked by immersing bricks in water for 48 hours and weighinh the water content.

4. Plug the holes with polifia or building mix, and paint.
This liquid can also be applied to the top of concrete slabs, with about 5 mm penetration, it wil stop water penetration. To prevent water penetration on top of painted boudary walls, sand the paint slightly off, enough to get SR 87 to penetrate, and soak the top 10 mm of the wall.
Rising damp is water from the ground entering a structure by capillary action. Rising damp can be cured by the installation of a chemical damp proof course supplied by Art-Damp for waterproofing and rising damp control.
Rising damp is a commonly encountered problem in some types of building. It is important that the investigations into dampness are undertaken by a trained and competent surveyor who can recognise and understand the problem.
Decayed skirting boards, crumbling plaster, discolouration and staining, decayed timber, peeling paint and wallpaper are all common effects of rising damp.
Most types of masonry used in the walls of buildings will allow some water movement by capillary action; however, this is usually controlled by a physical barrier or damp proof course. If this physical barrier is absent, has broken down or is damaged then it is often possible to install a damp proofing control to restrict water rising from the ground.
If you want to stop rising damp, look no further, Advanced Resin Technologies (ART) based in Johannesburg offers DIY products for rising damp control and damp proofing. Our products offer waterproofing on a wide range of materials:
- waterproofing walls
- waterproofing concrete
