New Crack Repair System Combines Epoxy Injection and Carbon Fibers
Standard crack sealing with urethane or epoxy will fill cracks, but do little or nothing to reinforce structural integrity or prevent future shifting and expansion. The structural surface seal injection system from Fortress Stabilization provides both a seal and a structural repair by combining carbon fiber stitching with epoxy crack injection.
Insert ports into the crack and measure out the carbon strips.
Lay the carbon strips over a base coat of epoxy along the crack.
Add a topcoat of epoxy.
Smooth out the epoxy topcoat, and then cover the repair with a coating or overlay if desired.
Cracks in concrete walls or slabs are traditionally just filled or injected. More than just a crack filler, the structural surface seal injection system from Fortress Stabilization provides both a seal and a structural repair by combining carbon fiber stitching with epoxy crack injection.
“Epoxy injection is a single plane and rigid. The carbon fiber strengthens the repair by transferring load away from the fracture in concrete,” says Todd Jackson of Fortress Stabilization. “We based the concept on our use of grids for joint repair along with epoxy overlays for segmental bridges.”
The installation process is similar to traditional epoxy injection, where ports are set in the crack and injected. The carbon fiber strips are then applied over the crack and embedded in a coat of epoxy resin, becoming an integral part of the repair. After the epoxy sets, you can disguise the repair by smoothing out the surface and applying a coating or overlay.
The structural surface seal injection can be used to eliminate crack expansion on both vertical and horizontal concrete, including poured walls, flatwork and bridge decks.
