Description
We Prepare the surfaces by removing all existing deteriorated plaster up to a height that exceeds the obvious maximum line of rising damp by at least 50 cm. Brick walls (1 row of holes) (1) Drill 12 mm-diameter holes in the wall, reaching all the way to 5-6 cm from the opposite side, at a distance of 12 cm from each other.
The most effective system is to drill horizontally in the direction of the mortar at a height of approximately 15-20 cm above the level of the ground or floor. Uneven stone walls (2 parallel rows of holes).
Drill two rows of 12 mm-diameter holes reaching less than 6 cm from the opposite side. The two parallel rows of holes must be drilled at least 8 cm from each other, the centre distance between the holes of a single row must be 12 cm and the holes of the two rows must be scattered by 6 cm so as to obtain an injection network of alternate holes. Damp continuous walls in contact with other units .
When it is necessary to treat a portion of damp wall that is shared by different properties, that do not intend to restore it, we emphasize the importance of isolating the treated portion of the wall with two vertical injection bands carried out at either end of the area requiring restoration, reaching a height that stops the damp from by-passing through adjacent areas. Foundations at different levels.
If there are continuous walls built on foundations of different levels, when making an injected curb with the function of stopping capillary rising damp, it is necessary to maintain the same distance from the terrain, accordingly, we follow the outline. Building corner. If we only intend to treat a wall corner locally (a partial action, and therefore not recommended) it is advisable to extend the treatment curb against capillary rising damp by at least 1 m along both sides of the area being treated. Once the holes have been drilled, we clean them out by blowing or vacuuming out any residues. Next, inject our solution into the hole until it is no longer absorbed. Average product consumption is 10 cc/m for every cm of thickness of the wall. After the solution has been injected, we plaster the holes with quick-setting mortar . After the treatment against capillary rising damp, to eliminate the damaging effects of the drying salts, it is necessary to plaster the walls with damp and salt proof plaster.
