Abstract
Disclosed is a system and method for providing a concrete crack repair system that is capable of providing a pressurized seal that continues to resist the ingress of water even as the crack continues to open and close over time. A compressible seal is provided that may be inserted into and adhesively joined to a machined groove that follows the contour of the crack in the concrete surface. After its installation in the machined groove, grout may be injected into the machined groove below the compressible seal so as to fill the space between the compressible seal and the bottom of the machined groove, which grout may also flow into the groove that is adjacent the bottom of the machined groove, thus allowing pressurized grouting of the crack itself. The compressible seal may also include an interior, hollow chamber that may allow inflation of the compressible seal within the machined groove, thus forming a permanent pressurized seal above the crack.
