A Guide to Epoxy & Polyurethane Injections, Lexington-Fayette Northeast, Kentucky

Concrete is a durable material used for a range of residential and commercial purposes, from patio to foundation repairs. The material is not immune to cracking, however, and that can cause issues like water damage and mold overgrowth. If you discover gaps in your concrete surface, arranging concrete repairs to fill those openings is the first step. A technician will determine whether an epoxy or polyurethane injection is the most effective option. Here’s what you need to know about these common solutions.

Epoxy Injections

By combining epoxy with a hardener, this solution can vary in texture from thin to viscous. This makes it particularly versatile and is often the first choice of technicians when the concrete requires specific structural attention. Technicians depend on it for concrete repairs because of its strength and durability so that the filled crack is just as strong as the surrounding concrete. For large or wide-reaching cracks, thicker epoxy is necessary.

The downside of using an epoxy fill is in the cure time. Depending on the thickness of the solution, it can take several hours for it to harden properly. However, this can be helpful if the concrete has multiple fractures. The extended drying time allows the epoxy to settle into minuscule openings and create a safe, even surface.

Polyurethane Injections

The material can be mixed in several different ways to produce a certain texture, be it foamy, rubbery, or hard. It’s typically used to seal cracks and create a waterproof barrier that prevents leaks and mold from developing. Since the fill expands in the space, it’s easy to fill even the smallest openings.

Polyurethane is a reliable concrete repair solution because it dries so quickly. The majority will harden within just a few minutes of injection, which makes it an excellent option if you’re concerned about the fill leaking out of the crevice.
