The solution against rising damp
Rising damp is one of the biggest challenges in existing construction. It requires special treatment, as it starts from the ground and extends up to the walls (it impregnates the structural element). Its appearance in habitable areas creates damage and problems, both internally and externally. Internally: creating an unsightly image (traces of salts, swelling and even disintegration of coatings), but also mold growth and unpleasant odors. Externally: alteration of the materials and in particular disintegration of the coatings, carbonization of the concrete and possible oxidation of its (steel) reinforcement. What is rising damp?
PROPERTIES Highly penetrating and hydrophobic silicate solution. Protects against rising damp by injecting the product into walls. During the application, the reaction between the silicate solution and calcium hydroxide contained in building elements, results in the formation of insoluble compounds and the formation of hydrophobicity in the treated elements. In this way, the capillary pores of the building elements are sealed, preventing damp from affecting them. ADVANTAGES •Does not corrode concrete rebars. •Yields high hydrophobicity of the building elements. •Does not block breathability (after the application). APPLICATIONS HYDROSTOP WALL creates a hydrophobic horizontal barrier against rising damp in walls or concrete structures, by drilling into the application element. It is also applied in cases of existing wall damp, by impregnating the surface. USE Surface preparation The product is applied by drilling and injecting it, with or without any pressure applied. The drilling points and the distance between them are determined by the composition and absorbency of the wall. 1. Pressure-free application Begin by drilling holes into the wall. The required hole size is 16mm in diameter, 15-20cm apart and at an angle of 30°- 45°. Drill holes at two levels (one set of holes to be drilled up and one down). The depth of the holes is calculated to be less than 5cm from the overall wall thickness. Coat both sides of the wall with the waterproofing mortar D-1 to prevent HYHYDROSTOP wall Hydrophobic silicate solution Proposed solution by DUROSTICK!
DROSTOP WALL from leaking through. Thoroughly clean the holes with compressed air. Use the practical packing with the built-in spout to pour the product easily. Pour the product into the holes until the masonry is saturated without forcing it, just by using its natural flow. 2. Pressurized application This method is suitable for walls that are greatly or even completely impregnated with water. Drill holes into the wall. The required hole size is 12-18mm, 10 to 18cm apart and at an angle of 30°. When working with low-absorbency DUROSTICK D-1 BRUSHABLE WATERPROOFING MORTAR FOR WALLS, FLOORS, BASEMENT & ROOFS Tip Apply the waterproofing mortar D-1 on both sides of the drilled walls to prevent HYDROSTOP WALL from leaking through.
walls, it is necessary to drill holes at two levels. Apply the product by using an injection machine until the product leaks from the surface of the wall. In both cases (after the completion of the HYDROSTOP WALL application), allow for the treated surface to rest for at least 24 hours and then seal the holes with D-11 SUPER FAST or DS-247,of DUROSTICK. 3. Impregnation The wall must be free of loose sections and dust. Apply at least three successive coats, without any dilution, until saturation. Each coat follows, as long as the previous one is still wet (wet on wet). In cases where hydrostatic pressure exists, first use HYDROSTOP WALL as a primer (double coat), and then apply the waterproofing mortar D-1 of DUROSTICK to seal the walls. Application methods
