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.
Multi-ratio pump for versatile applications
The Prime Dual Flow SS is a powerful and versatile multi-ratio, air-operated unit designed for everyday use with the municipal grout crew in mind. It consists of two air motors with heavy-duty, stainless steel lower piston and cylinders that operate independently of each other. The Prime Dual Flow SS is ideally suited for pumping Hydro Gel SX at multiple ratios or Prime Flex 900 XLV at a 1:1 ratio with water. It can also be used to pump many of the Prime Flex products as a single-component material. The stainless steel also means that acrylamide like the PR10L ACLM from Prime Resins can be pumped with no worries of rust. The operator manually controls the mix ratio. Use the air regulators to adjust the speed of each motor separately and / or use the valve positions to control the ratio of water and grout.
