St Louis, Missouri-Chemline has developed a convenient, strong and quick-cure concrete repair: material, Chemcrete 1800. This new two-component polyurethane is a deep penetrating polymer that cures to the strength and durability of concrete within 10 minutes, according to John Henningsen, marketing manager for Chemline.
Henningsen points out that repairing cracked and broken concrete is time consuming, with hours of preparation and installation needed, even on small repairs. When this involves cold temperatures -freezers, coolers or Northern latitudes-Henningsen said Chemcrete 1800 "eliminates most of the time-consuming, messy prep work and provides permanent repairs in minutes."
The product will cure in ten minutes, even at -40°C. And another bonus us that for repairs on concrete joints or thresholds, the area is ready for heavy vehicle traffic "within minutes," the company says.
Chemcrete 1800 has a very low viscosity, but while "It's as thin as water," it will not freeze when exposed to frozen base concrete, Chemline said.
The company feels that its new repair system offers labour savings of 80 percent over conventional repair materials and practices.
St Louis-based Chemline Inc. makes spray-applied, high performance polyurethanes, polyureas and epoxy polymers for many industrial and construction uses.
