Often due to increased humidity, the outer wall is damp, which necessarily causes the destruction of the plaster. The time has come to start a reorganization. To dry the wall, you can use the horizontal capillary moisture -generating system.
If we compare the old buildings with modern ones, then in the latter it is necessary to resort to measures to prevent moisture to penetrate by creating jumpers that interfere with moisture intake. 1. Raw wall leads to the destruction of masonry and plaster. 2. In addition to moisture, the walls are also corroded from salt released during the evaporation of moisture. This can only be eliminated after the cessation of moisture in the thickness of the walls. For drying the walls, a method called “injection by the composition of Hydral HS” is used. This method is as follows: on the wall on the outside, holes are drilled 8 -15 centimeters from each other. The height of the Earth is small. If you drill from the inside, then their location should be at the floor mark or if there is, then the cellar. The diameter of the holes depends on the absorption capacity of the wall and is usually 15-25 mm. Depth – 95% of the thickness. Drill, directing the drill down at an angle of 30 – 450. After that, dirt and dust are removed from the hole, and a dosage cylinder is laid in each hole. Due to the good penetrating ability of the sanitizing composition, uniform impregnation occurs. After passing the reaction in the wall, a layer creating a barrier to penetrate moisture is formed. The drying process is created. Then the hole in the wall is sealed with a cement (one part of the sand is placed in three parts of cement). After six months, you can start plastering the wall.
Specification of work: 1. There is a wall that is constantly damp. 2. The holes are drilled based on the thickness of the wall, at the same distance from each other and with tilt down. 3. Clean holes and insert cylinders with the composition. 4. The holes are sealed with cement and after 6 months they are plastered.
