Parson Environmental Products
Eliminate the growth of bacteria that causes Microbial Induced Corrosion (MIC) to manholes and similar structures with ConBlock MIC. This is a liquid additive for Parson MH Liner and CA Liner 100 that is very effective against mold, fungi, algae and damaging bacteria. When added to the mix, the antimicrobial polymer that is formed keeps the surface free of excess bacteria and mold buildup. This treatment cures into a cross-linked polymer, bonding with the aggregate and cement to impact durable protection without migrating out of the concrete. 800.365.9023,
