The future is already here-negative sealing with crystal and injection technologies

Apart from the familiar and traditional sealing systems used (most often) for positive (positive) sealing, our company is engaged in the implementation and study of advanced sealing techniques in order to refine the range of solutions offered to its customers and to provide a complete sealing envelope even in cases requiring special design

Sealing with injection molding is accomplished by using low or medium pressure electrical or pneumatic systems for types of liquid (two or one-component) polyurethane, acrylic gel or crystalline bonding materials for existing cracks in cast or sprayed concrete surfaces
The injected materials have unique properties of creating a ‘reaction’ in contact with moisture or water. As part of the treatment process, pressures are injected into cracks or voids (including pockets of aggregation) that create a chemical reaction of swelling and / or solidification upon contact with water or moisture and thus “seal” the crack or cavity and prevent water penetration through the wall into the structure

Injection sealing method is suitable for places that have water infiltration (groundwater or rainwater) usually in underground structures: basements, shafts, parking lots, shelters where negative sealing is required. However, injection sealing can be performed from both the outside (positive side) and the inside of the structure (negative side) against the outside water pressure

Crystal sealing systems are designed to respond to negative and positive seals. The system is characterized as an additive for concrete castings or as an application system after building the skeleton / concrete element
The system is applied by smearing or impregnating (impregnating) the sealing material in the concrete substrate intended for sealing. The properties of crystalline material are to be absorbed and wander ‘in the concrete infrastructure and during the encounter with moisture and water, a catalytic process of reaction and crystallization of the materials is created, thus preventing the passage of liquid molecules in a rapid manner, but allowing the passage of air molecules in the infrastructure. The treatment of the concrete and reaction storage facilities can also happen years later from the time the system is implemented

The technique is proven to have significant benefits in extending existing structures, preventing corrosion and rust formation, chemical resistance, and corrosion – can be applied in both negative and positive sealing situations
Choosing a sealing system as a suitable sealing solution over time is a direct derivative of a number of characteristics that influence the writing of the technical specifications
