What Is the Process of Concrete Crack Injection? Concrete crack injection means injecting the crack site using durable materials. The rate at which any material fills the crack is referred to as "injection." When someone fills the fissures, it makes room for more air pockets. The air pockets make the concrete susceptible to cracks or worse in the future. Make sure you fix the concrete to make it better and look like new. Is it better to use epoxy or polyurethane for crack injection? Polyurethane or epoxy can help you get the job done. Both epoxy and polyurethane can bind within the crack, so you must seal from front to back and require low pressure. Almost in all cases, you can do this at home using a crack injections kit. Epoxy Injection materials that use epoxy are available in a versatile range of consistencies, like a thin substance or a thick paste. The choice of consistency can depend on the size of the fissure. You can choose a paste-like substance for larger cracks that provide more control. The best advantage of using epoxy mixes is their strength. It is a solid substance that makes cracked concrete stronger for a long time if injected correctly. One of the drawbacks of using epoxy is that it is susceptible to leaks when not managed correctly. Polyurethane It looks like a foamy substance. Polyurethane sets fast and reduces leaks and further damage. They are water-resistant, which safeguards the work from a dreaded water problem. The main disadvantage of polyurethane is that it adds no strength or resilience to cracked concrete and is ineffective for complete structural repair.
