Skip to content Hydroguard is a ready to use leak sealing solution, based on the hydrophobic silicone compounds for the water-repellency and silicification by injecting.
Injection waterproofing is a way of damp-course carried out by pumping specific products through the prepared holes in the ground, adjoined to the building constructions, constructions, or in the seams and cracks of constructions.
The main objective of Hydroguard is the creation of a horizontal waterproofing barrier, performing old buildings repairing, if lime presents in the masonry composition.
Horizontal waterproofing barrier by Hydroguard may be provided only when there is no water stress, i.e., where there is no water outlet.
Hydroguard is used where the termination of the capillary suction of water is necessary to achieve by the production of an internal hydrophobic effect and narrowing or blocking the capillaries inside the concrete and masonry.
The capillary structure is blocked due to the hydrophobic solution interaction with the lime to form insoluble, non-absorbing chemical compounds.
Injection technology is well suited for the protection of the existing buildings and constructions from rising capillary moisture by creating a horizontal waterproofing.
The most common injuries that occur during repair of buildings is damage of walls, basements and structural elements, which contact with the ground, by reason of moisture penetration. The water in wet brick walls rises through the fine pores (capillaries) and cracks in buildings structural elements. As a result of the horizontal waterproofing, water rising stops.
Injection waterproofing is effective in the next cases:
The injection under pressure: The injection under pressure is recommended when the masonry to be treated is already considerably or completely saturated with water. When applying the hydrophobic agent under pressure, the materials impregnation degree is up to 95%. When injected under pressure, the constructions processing time is significantly saved.
The boreholes arrangement is determined by the type and condition of the masonry.
The diameter of the boreholes should be 18 mm. The distance between the centers of boreholes must usually be 10-12,5 cm. Boreholes can be drilled horizontally or at an angle of 30°. The depth of the borehole should be approximately 5 cm less than the wall thickness.
For dense, weakly absorbent or non-absorbent masonry it is preferable to use a double-row boreholes arrangement. For absorbent masonry of natural stones the holes should be drilled in the stones, and when dense rubble masonry - in joints.
The corners and walls over 60 cm thick must have boreholes on both sides.
Please remove drilling dust before saturation.
Hydroguard is injected at a pressure of about 10 bar through the injector tip 400 or 600 mm.
The injection without forced pressure: Water-repellent composition is supplied by gravity, without pressure. Injection holes should be drilled at intervals not exceeding 15 cm, diameter of 30 mm and an angle of 45 to 30°. The depth of the borehole should be approximately 5 cm less than the wall thickness. When drilling holes please ensure the holes to be extended through at least one horizontal joint of masonry, in the case of a thick wall – at least two.
It is recommended to drill holes in two rows by height. The distance between the centers of the holes is calculated based on the masonry absorbency. The smaller this distance, the higher reliability of water proofing is achieved. It is recommended for drilling to use not vibrating electrical drilling machines with appropriate drill bits.
For the wall thicknesses more than 60 cm and on corners boreholes should be drilled from both sides.
Remove drilling dust before saturation.
Hydroguard is poured into the borehole. The most expedient is to inject from the additional vessel (hopper with pressure plugs). The saturation time should be at least 24 hours.
For open joints, cracks or voids sealing use the same procedure as for pressure injection method.
