Epoxy injections are designed and used to restore strength and. Epoxy crack injection (also known as epoxy injection) is an extremely effective and reliable concrete crack repair method, which is used exclusively for the repair of cracks of poured concrete foundations, for structural repair thereof, for repairing leaks in the basement and to avoid pouring concrete foundations. cracks due to leaks in the future. When used under the right conditions and when done correctly by a trained injection technician, epoxy concrete crack repair does not fail.
Before proceeding to a crack repair using epoxy injection, the cause of the crack and the need for structural repair must be determined. If the crack does not compromise the structural integrity of the structure, injection with polyurethane grouts or other non-structural materials may be a more suitable option for filling the crack. When structural repair is required, the conditions that cause the crack must be corrected before proceeding with epoxy injection. The application of such materials can be completed by a basement waterproofing contractor or a do-it-yourself homeowner.
Either way, the repair of concrete cracks in the foundation or slab can be completed efficiently and effectively in as little as an hour or more. How long does it last? Crack injection, properly installed, should last the entire life of the structure. This type of injection is done from the inside of the basement, thus avoiding the need to excavate the foundation. Epoxy crack injections are typically performed at lower injection pressures (20-200 psi) and with surface mounted ports.
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. While epoxy crack injections are not as versatile as polyurethane crack injections, for example, the repair of active leaking cracks that contribute to a damp basement, the use of epoxy is nevertheless a very effective means of repairing concrete cracks and preventing possible leakage in the basement. The technician starts injecting epoxy cracks through the lowest injection port until the epoxy travels through the crack and becomes visible at the injection port immediately above it; the lowest injection port is then plugged and epoxy is injected into the port immediately above it. With so much information published on the Internet, anyone who researches epoxy injections will find conflicting opinions about whether this type of repair really works or not.
This method requires a little patience, but it allows the applicator to control the injection process and ensure that the crack is completely filled. Repair of concrete cracks with epoxy injection is the most reliable sealant to use, as it is incredibly strong and reliable. If the crack has been previously injected and the original epoxy has cracked, it may be almost impossible to find the exact place to re-inject and, since the rest of the repair is a solid mass, the epoxy cannot flow to find the cracks. Do not hesitate to contact us if you have a crack in the floor or ceiling and are wondering if an injection of concrete epoxy is suitable for sealing it.
Dual cartridge dispensing, which uses disposable or reusable cartridges or containers, is a cost-effective and completely portable method for injecting two-component polymers. Let's compare some of the main characteristics of each type of crack injection, describing their strengths and their range of recommended applications. For example, injecting curtain with PU gel into the space between the structure and the floor requires lower injection pressures but higher rates of material flow. When you need to repair a crack in a concrete structure, such as a foundation or a wall from the inside (negative side) of the structure, there are usually two injection techniques and corresponding product technologies that you should consider epoxy resin injection and polyurethane chemical grout injection.
