Coating on Precast Structures

We offer a Coal Tar Epoxy coating that assists with water-proofing your precast structure.  The Coal Tar Epoxy coating acts as a secondary barrier against any ground-water infiltration and any sewer that may try to escape.  We have used several different variations of this product, some being: Carboline Bitumastic 300M and Tnemec 46H


Our 100% Solids Epoxy coating is an Anti-Microbial coating designed to prevent corrosion inside of sewer structures caused by the sewer gasses trapped within the structure or sewer system.  We are experienced in the application of 2 different types of this coating.  Carboline Semstone 140 and Tnemec 218/434.
