Epoxy/Polyurethane Injections

Epoxy Injection

Epoxy injection is a procedure to "weld" cracks in concrete together, which improves its performance and extends its useful life. It involves a low viscosity epoxy resin mixed according to specifications and pumped under pressure through drilled holes that intersect the crack, and/or through injection ports mechanically or epoxied in place over the crack.

Polyurethane Injections

Polyurethane injection is most commonly used for water control by injection into cracks or joints to form a gasket, by injection through a structure to form a barrier between structure and soil, or by injection into the soil to consolidate the soil into a monolithic, impermeable barrier.

"The workmanship was
professional and the
results of the grouting
are impressive. It is a
pleasure to work with
someone who does what
they say they are going
to do, when they say they
are going to do it."

Eric Nilsen, Maintenance Coordinator; Mesa County Valley School District 51


Polyurethane resins or grouts form gels, foams or solids, and are hydrophilic or hydrophobic. They are very stable, and have good resistance to acids and alkalis. Life expectancy of polyurethanes can be measured in one to two decades. These resins have many desirable qualities, such as expansiveness, adherence to wet or dry surfaces, controllable set times, a tenacious bonding ability, chemical resistance, and are reacted by the very water that you may be trying to stop.

Mays Construction Specialties, Inc. has been using polyurethane resins for over ten years, and in many different types of applications, including soil stabilization and injection into rock strata, dams, water tanks, water treatment plants, pools, and residential basements.

MCSI has many pieces of specialized equipment necessary for a wide range of projects and has trained personnel with years of experience to assure the results required by our clients.
