Hycrete’s W500 admixture protects concrete from damaging moisture and corrosive materials. Specifically designed for less-critical waterproofing applications, the admixture is dosed at 1 gallon per cubic yard of concrete, working well as a secondary line of protection for both above- and below-grade construction. W500 is based on Hycrete’s core admixture technology, and all of the company’s products use at least 80 percent pre-consumer recycled content. Low-VOC content helps W500 contribute to LEED points. www.hycrete.com; 201.386.8110.
