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.
Precision Fill is a two-component, low exotherm, polyurethane foam used to fill voids and underseal concrete slabs. Its low viscosity allows for moderate permeation effects as well. The resin produces a closed cell, high density structural polyurethane foam
When cured, Precision Fill exhibits a compressive strength of 24 psi/3,456 psf (ASTM D-1621), expansion of 23x, density of 3 lbs/cubic ft, and no shrinkage (ASTM D-1042 / D-756).
