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 ® 4.0# Slow is a two-component, polyurethane foam used to fill voids, stabilize soil, and to underseal concrete slabs and foundations. This closed cell, hydro insensitive, high density structural foam is engineered for compaction grouting of soil and for filling voids behind and beneath slabs, pipes, walls, manholes and other structures. This slow reacting formulation allows for greater permeation. The slow reaction is ideal for void filling and can also provide lift if desired.
Slower set time = denser foam
Cream time: 25 seconds
