Yes, it is. It’s environmentally friendly and it has many sustainable uses. It can be repurposed, recycled, and ground down to be used in new mixtures if need be.

It’s a porous material that allows for water to pass through it. It’s strong, absorbent, and perfect for use in areas that experience severe weather regularly as it controls runoff and rainwater build-up.

In short, it’s an essential part of building and when used responsibly by professionals can last for many years – before being turned into something else.
