Semstone 305
A polymer concrete that is an excellent alternative to acid brick. It is used to protect Portland cement concrete from attack from a wide range of aggressive chemicals. It can be applied from 1/2” (12.7 mm) to several inches thick. It provides a monolithic surfacing that has excellent resistance to impact and mechanical abuse and can be used to restore and protect degraded surfaces in a single application.

Semstone 805
A flexible epoxy polymer coating and lining providing a chemical, water and abrasion resistant barrier for steel and concrete. This versatile coating system was developed as a self-leveling, flexible chemical resistant coating and lining and can also be used as a high build coating and lining system with the addition of a third component. It is a 100% solids, low odor, two-component system applied either as a neat system (unfilled), a reinforced system, an aggregate-filled system or as an aggregate-filled reinforced system.
