The geotechnical needs of DOTs and other agencies responsible for roads and bridges are vast. Issues include: Culvert repair Soil stabilization Void filling Concrete slab lifting Sinkhole remediation Slope control Slough control in tunneling
Protecting concrete usually means shielding it from the elements of nature or from harsh manmade chemicals. But it’s not just concrete that needs such protection. Corrugated metal pipe, steel surfaces, material hoppers, rail cars and masonry all can come in contact with corrosive or abrasive materials or harsh conditions.
StainShield concrete protector shields surfaces from resin and epoxy stains. Use this concentrate diluted with water to reduce or eliminate the discoloration from, polyurethane lifting foams, polyurethane or epoxy grouts, and polyurea or epoxy joint sealers. These foams, grouts and sealers normally leave a discolored area on the surface of contacted concrete. This discoloration is exposed when removing inadvertent overﬂow from cracks, joints or drilled holes. This discoloration is often unsightly in an otherwise ﬂawless project.
