Technicians utilize the power of vacuum to present unparalleled repair processes.
Originally developed in Europe, the processes have been utilized in North America since 1985. Unlike pressure injection, the vacuum processes withdraw air and moisture from cracks prior to the installation of appropriately selected repair resins. The tendency to burst the damaged member, so characteristic of conventional pressure methods by compressing the liquid repair resin, is totally eliminated. Thermal expansion of arrested air can degrade the repaired concrete, masonry or stone in time. There is no residual water or stress concentrations at the ends of cracks using vacuum processes.
