for larger joints (10 - 25mm) EnviroSTONE uses an environmentally friendly, organic binder to join the fines of crushed stone together with its larger particles. Water activates the binder, which swells into a glue-like gel. After saturation, the stone will harden to minimize erosion and weed infestation while giving the strength needed in your joints or base.

EnviroSTONE will flex with the settling of the ground or frost movement to prevent cracking; a common problem found in concrete mortar joints. Because the EnviroSTONE is reusable, you will be able to easily remove it whenever needed. It does not need to be a permanent structure and can actually be used elsewhere in the future. In extreme conditions where damage may occur, it will actually heal itself with the next rainfall. Above all, our binder is ORGANIC and Environmentally Friendly!

Because of its larger particles of aggregate, the EnviroSTONE has a much greater integral strength than any sand and is therefore scientifically designed for a larger joint application. Unlike other synthetic or "Polymeric" materials, EnviroSTONE (because of its Organic Binder) can actually re-heal itself. In conditions where cracking or movement may occur, the onset of water, heals the stone dust and continually molds itself back to the shape of the joint.
