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.
On Old Redwood Highway (US 101) in Healdsburg, California, commuters were noticing that approach slabs were sinking. There was a noticeable drop and the typical ‘thumping’ associated with the uneven sections. The drops were as large as 2” in some places. The California Department of Transportation sought to fix the uneven slabs as well as stabilize surrounding soils under neighboring panels. Learn how Precision Lift 3.0 from Prime Resins was able to address this issue. Check out the case study here.
