Polyurethane concrete patch repair

The cured product creates a compression seal of varying flexibility. Polyurethane foam resin often utilizes an activator or accelerator. Resin and activator are mixed before they are injected. Polyurethane resins are also available in two component chemical cure variants. No moisture needed. Polyurethanes are extremely versatile. Their chemical and physical properties vary to suit the needs of specific applications and jobsite conditions. Polyurethane resins vary from rigid and strong to flexible, rubbery and soft.

The initial cure time for crack injection polyurethanes is generally 1 — 10 minutes and is influenced by accelerator usage, temperature and moisture availability. Epoxy crack injections are typically performed at lower injection pressures psi and with surface mounted ports. Polyurethane crack injection is often performed at higher pressures to move the expanding foam through the cracks with special injection pumps and packers installed into drilled holes.

The injected polyurethane is supposed to fill the crack through the entire thickness of the structure thereby preventing water from entering the crack. In non structural water related repairs PU is generally the material of choice. This is true for most below grade repairs including basements, tunnels, parking garages and manholes.

PU is a good void filler and is also used to stabilize dirt and lift structures. EP is an excellent adhesive for structural repairs of stressed concrete substrates and deteriorated concrete structures. Complete line of packers: S-Type, R-Type, custom sizes, Hammer-in packers, surface ports, specialty packers.

There are many exceptions. For example curtain injection with PU gel into the space between structure and soil needs lower injection pressures but higher rates of material flow. The filling of larger voids and joint injection also uses lower pressures. PU injection through surface ports is not common, but high pressure epoxy injection through packers is seen more frequently.

Epoxy and Polyurethane Resin Based Crack Repair Systems are the Superheroes of Concrete Crack Repair When you need to repair a crack in a concrete structure — such as a foundation or wall — from the inside negative side of the structure, there are typically two injection techniques and corresponding product technologies that you need to consider — epoxy resin injection and polyurethane chemical grout injection.

There is an injection solution to most concrete crack related problems. But, there is no one-size-fits-all solution. Does your crack impact the structure? Do you need to restore structural strength to the structure? Does the crack carry water? Sign In Create an Account. My Cart. Skip to the end of the images gallery.
