Notable Differences Between Chockfast® 3 Component Epoxy Grouts & 2 Component Epoxy Chocks

Learning the difference between epoxy grouting and epoxy chocking installations is easier when you learn the subtle differences between grouting systems and chocking systems. Grouting and chocking systems are both designed to withstand thermal shock, vibrations, and physical pressure, common in industrial installations.

A Grout is commonly defined as dense fluid which is used to fill gaps or used as reinforcement in existing structures or new structures. A Chocking system is a high load bearing material used to provide precise equipment alignment, dampen machine noise and vibration, prevent loosening of threaded bolts. A proven brand widely used in a number of applications globally that can be used as a successful example for each is the Chockfast brand of epoxy-based grout and epoxy-based chocks.

Chockfast three-component Epoxy Grouts consist of resin, hardener, and additional aggregate. The additional aggregate allows these materials to be poured in larger volume areas than the epoxy chocks. Recommendations for formwork and overpour dimensions are much more general than those for epoxy chocks.

Chockfast two-component Epoxy Chocks consist of resin and hardener and are typically used as “pourable shims.” Volumes of individual chocks are limited due to the exothermic nature of the material, which results in very high physical strength properties. Recommendations for formwork and overpour dimensions are much more specific than those for epoxy grouts.
