Prime examples are bridge decks or other self supporting structures, where the most common delamination is shearing of the concrete. This is commonly at the upper rebar mat.

Another common situation is the hollow plane that develops when concrete bridge piers are resurfaced or the old piers are encased in new concrete. Hollow planes develop, especially against the smooth sections of the old pier. Cracking then occurs on the surface perpendicular to the hollow plane. Delamination then occurs along the hollow planes that run along the reinforcing bar.

The epoxy resin, when injected, will travel or flow through these hollow plane areas for several feet filling in the voids and preventing further delamination.

Grout-Tech uses epoxy injection to repair and restore damaged concrete structures and members. We repair bridges, overpasses, and reinforced concrete decks, pillars, posts, and columns.

We use a SIKADUR product that we feel is the one of the worlds finest polyurethane resins system to in our repairs. This multi-purpose injection resin is designed to seal leaking cracks, voids or fractures in concrete structures.

Many specialty grouts can be used with an accelerator to adjust the reaction profile as needed for job site conditions. The system can be accelerated to achieve specific reaction times by mixing in specific amounts of accelerator.
