Instructions

1. Drill three holes per brick along the wall, 2 bricks above ground level (9mm drill bit, 260mm long)
2. Vacuum the dust from each hole.
3. Pour SR87 using a plastic bottle with a narrow tip, until full saturation.
4. The liquid will flow down in a triangular flow pattern starting from the seconr or thrid brick.
5. Estimated amount required for full saturation: 250  of SR87 per linear metre of wall.
6. Plug holes once bricks are full saturated, using standard mix of building sand and cement.  

Notes

By saturating a brick internally with water - repellent compound, and subjecting it to positive pressure from the humidity (pressure from outside the brick towards the inside of the brick), we ensure an efficient method to stop rising damp. Most attempts to block humidity by appling water - proofing materials on the surface. will fail as the material is facing negative pressure, from inside the wall pushing it outwards.

1. We have designed a steel jig to facilitate the drilling operation, quickly and neatly without damage to the wall. Just push the jig against the wall, press it against the wall with one foot and drill.
2. SR87 liquid must be poured into each hole, as many times as required until it stops been absorbed. It may take 10 minutes to over 1 hour for one dose to be absorbed, depending on the density of the brick or concrete.
3. Clay stock bricks take about 10 minutes to absorb 18 ml (each hole is 6 ml, by applying 3 times in each hole, and 3 holes per brick (4,5 bricks per linear m), we achieve an impregnation rate of about 250 ml / linear m along the bottom of the wall.
4. ​Cement stock bricks take about 1 hour to absorb 18 ml. The cement in the brick will reach with the liquid, and become water - repellent.
5. ​Hard Clay Face bricks take about 1 to 2 hours to absorb 18 ml.
6. The degree of saturation of the brick will determine the efficacy of the process. Failure to saturate the brick along the entire section where damp is rising may result in an inefficient procedure. Some damp may escape through the poorly saturated section.
7. The liquid will flow down in a triangular flow pattern starting from the third brick and will overlap as it reaches the first brick, therefore ensuring a continuous saturation zone along the first brick, at the base of the wall, and above the floor level. In effect this saturation line will become a chemical damp course, preventing water from infiltrating by capillary action and rising up the wall.

The top of parapet walls can also be saturated with SR87. which will be facing rain water from outside, positive pressure. Horizontal floors can also be saturated with SR87, provided the humidity problem comes from the top of the slab (as in rain) and not from below the slab or floor, which is a negative pressure on the structure.

As the procedure and application of this product is out of A.R.T. control we ore not responsible for its efficacy and long term durability. Any sections of the wall which seem to have been poorly saturated can be easily and economically repaired by repeating the procedure in the affected area.

Important Notes

1. COVERAGE: ONLY 500 ML PER LINEAR RUNNING M. THE LEAFLET SAYS 2 TO 3 L BUT IT IS NOT NECESSARY)

2. TO OBTAIN 500 ML / LM, POUR 10 TIMES INTO EACH HOLE. Each hole is 8 mm in diamer, and holds only about 50 ml of liquid. One LM of wall has 4,5 bricks, and we drill 2 holes per brick, therefore 1 LM has 9 holes x 50 = approximately 450 ml of liquid / LM

3. The Liquid bonds chemically with the cement in the mortar or the brick. It will bond for 20 years. And make the cement / mortar water repellent. It is CRITICAL TO ADD AT LEAST 500 ML / LM to make sure that there is enough liquid in the 2 layers of mortar above paving / floor level.
