Leakage of underground concrete structures, such as basements and building structures, can significantly reduce the service life of a building due to corrosion of steel and damage to concrete, and reduce usability and functionality. To avoid the costly cost of repairing the structure or repairing damage to damaged interiors, furniture and other equipment, plus operating costs while the space is not in use, these leaks can often be securely sealed and watertight by injection molding.
Water penetration can occur through cracks caused by structural displacements, structural joints and deficient waterproofing.
The first key success factor is the correct choice of injection materials where a particular injection product meets the defined project requirements. This applies in particular to the viscosity of the material, flexibility and contact behavior with water as all these factors will significantly affect the efficiency of the injection.
Appropriate equipment for the selected injection material, including proper preparation, mixing, and injection process is another key success factor. That is, all stages from initial dosing and mixing, through the injection process with a suitable pump to the use of a proper packer.
Third, the correct manner and application of the injection technique must be performed by trained, competent and experienced contractors, in order to ensure a successfully performed work that will provide a complete and durable solution for sealing the structure.
To prevent the passage of water through the structure into the building, the points of water penetration can be securely sealed and watertight by the injection process. For injection material, it is important to choose one that will adequately seal and respond to further attempts to penetrate water. Polyurethane resin DRACO FIX 300 reacts with water and forms a flexible foam suitable for waterproofing and sealing water penetration.
Due to the low viscosity of the resin, with minimal pressure, it penetrates deeply into the material into which it is injected. It is easy to install, environmentally friendly, solvent-free and highly resistant to fungi and other microorganisms. It is important to add a DRACO FIX 310 catalyst to the resin, which enables the resin to be activated and controls the curing time. The amount of catalyst required depends on the temperature and humidity of the injection site.
Cracks are the first noticeable indication of a change in material structure. They show that due to external influences the material began to lose its integrity, and thus its designed properties.
The aim of grouting cracks in concrete is to restore the original properties of the monolithic, complete component of the concrete structure, ie its adequate strength, stiffness and compaction. DRACO systems uncompromisingly protect your facility from water leakage!
