The process includes low-pressure and high-pressure injections depending on cracks in concrete structures. You might be wondering if crack injection works or not. According to our experience, about 99% of the time, crack injections solve the problem and not only temporarily but permanently. All injection products have the disadvantage of being somewhat unpredictable, because both hole drilling and material injection are done blindly.
While the success rate can be high, achieving 100% effectiveness is extremely difficult. And if a crack has been previously injected and the original epoxy has cracked, it can be nearly impossible to find the exact place to reinject. And since the rest of the repair is a solid mass, the epoxy cannot flow to find the cracks.
Epoxy injectionis typically done on dry substrates versus polyurethane injection, which works very well on wet and actively leaking substrates.
Epoxy injection is the preferred method when structural crack repair is desired. When your property or building starts to age, you may see cracks in the foundation of your property. If you are a homeowner, seeing or noticing cracks inside and outside the property's foundation can be a sign that a crack injection is needed. Crack injection services is one of the most widely used and adopted techniques because it is cost-effective, reliable and permanent.
Epoxy crack injections are typically performed at lower injection pressures (20-200 psi) and with surface mounted ports. However, the pillars will not seal existing cracks, which may still need to be injected to prevent leakage after the base has stabilized. These cracks, typically due to drying shrinkage, thermal movement or other causes, are usually minor and result in few problems. Civil engineers often recommend the injection of epoxy concrete cracks for structural repair of cracked concrete in applications such as road overpasses and elevated concrete structures; this is due to the high bond strength of epoxy.
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. If epoxy is injected into a leaking crack, water seepage can create channels through the epoxy, creating leaks in the new repair. At higher pressures, the liquid has enough force to overcome gravity and climb up the crack without filling the back, which is normally narrower than the front of the crack. As stated above, epoxy crack injection is not as versatile as polyurethane crack injection; therefore, not all cracks can be properly injected with epoxy resin.
This will reduce the possibility of leaks or explosions and allow time for the repair material to fully enter the crack. This paste is applied over the entire length of the crack in the base and, together with the outer floor, serves as a barrier to confine the epoxy resin within the crack of the base so that the injected epoxy resin is contained over the entire length of the crack. Because epoxy and polyurethane foams used for crack injection are two-component materials, it is critical to mix them in the correct proportions to avoid problems with unreacted polymers. This process is repeated until the injected epoxy is seen to come out of the crack at the top of the base, or until the crack has been filled to the finish.
Similarly, crack injection can work hand in hand with carbon fiber reinforcement to stabilize and reinforce the basement walls of poured foundations that have arched and cracked. Because these repairs are inconvenient and often costly, your best crack repair strategy is to focus on prevention and control. Most of the time, a crack in the foundation will widen over time and cause water leaks or possibly loss of structural integrity. Let the compression spring of the dispensing tool force the material into the crack with slow and steady pressure.
