Epoxy injection for Concrete Crack Repair in foundations, basements, beams, columns, slabs, walls and other concrete structures.

Injection of epoxies under pressure may be used to bond the cracks having greater than or equal to 0. This method is not applicable if the crack is active, the cracks are large in number, or when the water leakage can not be controlled. If the cause of the cracking has not been corrected, it will reoccur near the original crack. Extreme caution must be exercised when injecting cracks that are not visible on all surfaces.

Epoxy injection is commonly used to restore the pre-cracking condition of the member without increasing its strength.

Future cracking may occur at the same load as that of the original uncracked member but at different locations. Strengthening is provided by installing additional reinforcement across the failure plane in combination with the resin injection. Frequently, internal or external reinforcement is installed in combination with the epoxy injection for strengthening and restoration. If water is continually seeping from the crack, the flow must be stopped in order for epoxy injection to yield a suitable repair.

Other materials such as polyurethane resins may be required to repair an actively leaking crack. For many applications, additional preparation is necessary in order to seal the crack. Where a surfacing material has been removed using an acid or chemical solvent, prepare the crack as follows:. If a coating, sealant or paint has been applied to the concrete, it must be removed before placing the paste-over epoxy. Under the pressure of injection, these materials may lift and cause a leak.

While this method may appear to leave some ports uninjected, it provides maximum pressure to force the epoxy into the smaller areas of the crack. Moving to the next port as soon as epoxy appears will allow the epoxy to travel along the wider parts of the crack to the next ports rather than force it into the crack before it travels to the next ports.

Continue to inject and fill these voids. In situations where the crack penetrates completely through the concrete element and the backside of the concrete element cannot be sealed e. This most likely indicates that epoxy is running out of the unsealed back side of the crack. In this case the application may require a gel viscosity injection epoxy CI-GV or may not be suitable for epoxy injection repair without excavation and sealing of the back side of the crack.

Stop injecting. Wait approximately 10 to 15 minutes to allow the paste-over to begin to harden. If the leak is large e. Check to see that the paste-over is hard before reinjecting or the paste-over or ports may leak.

Another option for small leaks is to clean off the injection epoxy and use paraffin or crayon to seal the holes. This may indicate that the crack either expands or branches off below the surface.

This may also indicate that epoxy is running out of the back side of the crack. If the crack penetrates completely through the concrete element and cannot be sealed, the application may not be suitable for injection repair.

Solvents may damage surfaces to which they are applied. Cured material — Chip or grind off surface. The kit includes everything needed to pressure inject cracks.
