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.
AR 800 acrylate resin is a super low viscosity, hydrophilic grout that produces an elastomeric gel with variable set times. This three-component resin is used for leak sealing and soil consolidation. It is ideal for geotechnical applications in humid environments. The variable set time range is long—from minutes to more than an hour—and is adjustable in the field. The resin remains fluid until polymerization, allowing for excellent penetration, so it is a great choice for sandy or silty soils.
When cured at a 50% concentration, it is a white flexible gel that has the consistency of a soft silicone gel with excellent adhesiveness. Humid conditions allow the gel to remain relatively constant. The gel is permanently elastic; these dimensional changes are reversible and do not degrade the gel. All-stainless steel pumps/fittings are required.
