Crack injection in concrete: structural repair and dynamic repair. Waterstop Solutions helps restore the structural integrity of concrete by injecting high-quality liquid epoxy resin into defects. Cracking indicates that a concrete structure has been forced to absorb the energy of some kind of stress. Fortunately, there is an easy way to permanently repair such cracks without the need for costly and annoying digging or draining tiles.
Cracks in poured foundations can be repaired by low-pressure injection of an epoxy or polyurethane foam material. For the repair of cracks in concrete floors, there are certain epoxy and polyurea materials, suitable for such tile repairs. For many years, engineers have been looking for ways to fully inject repair polymers into cracked concrete structures. The general consensus is to seal the crack with a sacrificial epoxy and install injection ports every few centimeters.
Thick epoxy is then injected at high pressure into the crack with expensive resin injection pumps. The process takes a long time, the epoxy is brittle, the equipment is expensive, and the skill level is highly specialized. This makes epoxy injection slow, costly and not really effective in the field. I have cracked concrete walls, which need repairs, these are basement walls that have been stabilized with steel I-beams, the requirements of engineers have epoxy to fill the cracks.
Once cured, the repaired concrete cracks will be two to three times stronger than the original concrete, ensuring a durable and long-lasting crack repair solution. The system can be used to stop water jet, seal minor leaks, restore structural integrity, and waterproof and strengthen almost any concrete or masonry structure from the positive or negative side, below level, above level and underwater. Its low viscosity allows good penetration into the concrete structure to seal leaks and achieve a durable elastic seal. A spring-assisted dispensing tool allows complete control of injection pressures to keep them between 20 and 40 psi, the best range for complete crack filling.
Repairs are structural in nature and will move with concrete, not against it like very hard epoxies. Using low-pressure crack injection, foundation and basement crack repair kits seal basement cracks from the inside, eliminating the need to dig the ground from the outside of the foundation. But in some cases, you may need to follow other corrective measures, along with crack sealing, to ensure a complete solution. Epoxy resins for crack injection are available in a range of viscosities, from ultrafine to pasty, to accommodate cracks of different widths.
Polyurethane foaming resins are designed to expand with water to temporarily block the passage of water through the crack or vacuum. They are now widely used for structural injection to seal cracks, gaps and non-moving construction joints.
