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
Prime Flex 900 XLV polyurethane resin is a low viscosity, hydrophilic resin that reacts with water and expands to form a closed cell, watertight foam. It is typically injected under pressure to seal actively leaking joints and cracks in concrete structures, including hairline cracks. This product is independently tested and proven to meet NSF/ANSI Standard 61.5 for contact with potable water.
This one-component liquid has a low viscosity, allowing it to penetrate hairline cracks deep into the structure. When the material contacts water, it reacts to form a white, flexible gel-like foam that acts as a barrier, sealing the cracks that allowed water to leak.
As the foam reacts, it expands to fill the space and bond to the concrete to hold it in place, creating a closed cell mass that does not allow water to pass through or around it. The foam’s flexibility allows it to expand and contract along with the structure it has sealed, so it remains water tight despite temperature fluctuations.
