Wastewater Concrete Protection

Tnemec Co. Inc. recently introduced two new products, Series 434 Perma-Shield H2S and Series 435 Perma-Glaze, which protect concrete in extreme wastewater environments.

Series 434 Perma-Shield H2S is a modified polymer-mortar designed to combat severe corrosion. The durable, low-permeation lining protects concrete against the harsh chemicals and abrasion found in wastewater immersion service.

Applied by towel or spray to deteriorated substances, Perma-Shield can be enhanced with the use of Perma-Glaze as a topcoat, according to the company. The Perma-Glaze lining provides improved aesthetics and additional protection against abrasion and chemical degradation, and can also be used as a stand-alone coating that is self-priming, as well as for some direct-to-metal applications.
