Seismic Repairs/Upgrades

Following an earthquake, numerous concrete and stone structures are found to have fractured due to the shaking.  The cracks are then injected with an epoxy resin to return them to near original condition.  Epoxy resins generally have strengths far greater than concrete.  If performed correctly, the resulting repair restores much of the designed compressive, tensile, and shear strengths.  The repair also creates an impenetrable seam that prevents the intrusion of water, salts and harmful gasses such as carbon dioxide and hydrogen sulfide which can cause the corrosion of the reinforcing steel.  Epoxy injection of earthquakes-caused cracks is an almost universally accepted repair method.
