ArmaGrout

ArmaGrout epoxy and vinyl ester polymer grouts are three component silica filled polymer composites used frequently for machinery foundations. The many benefits of these polymer grouts mean they are the foundation material of choice for critical equipment where maintaining alignment is essential.

Equipment such as compressors, turbines, pumps and fans benefit from using high strength epoxy foundation grout. With equipment such as this, even the slightest misalignment can mean very expensive maintenance for bearings, crankshafts, pistons, rotors etc. And when they are at the heart of a plant or process, downtime to make repairs is very costly.

All rotating equipment has out of balance forces to some degree. The energy of these out of balance forces has to go somewhere, and is often seen as vibration or shaking of the machine itself. This of course leads to damage and costly repairs. Machinery design calls for the out of balance forces to be transmitted and absorbed in the equipment foundations. This is why the foundations for compressors etc are often very large concrete structures.

The epoxy foundation grout is the all important tie between the equipment and the foundation. The epoxy grout bonds to the equipment and the foundation, has a high tensile and compressive strength, has ultra low shrinkage as it cures, is crack resistant, and oil penetration resistant.

On the other hand cement grouts have low tensile strength, are not crack resistant, and not oil penetration resistant. The result is that under constant dynamic loads under compressors and other rotating machinery, the tie to the foundation can be compromised and lead to increasing machinery maintenance.

This is why epoxy grout is specified for critical applications. It is more costly than cement grouts, but offers key performance that the cement grouts cannot.
