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.
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
Precision Lift ® 4.75# is a two-component polyurethane foam used to fill voids, underseal and lift concrete slabs and foundations in wet or dry environments. This is a higher density formulation designed for supporting and lifting heavier structures. It can be used in wet or dry environments due to its hydro insensitive nature.
