Foam Concepts, LLC - Why use foam?

• Why use foam? • PUF for geo-technical applications You may ask “why foam instead of concrete or backfill.” Simply, foam is more cost effective and will outlast even dirt! Foam weighs 1/50 th as much as concrete or dirt and is basically impermeable to water, which means it is also very immune to erosion. (Compare foam to concrete)If you backfill a shaft or a void, surface water will ...
