-20mm Recycled Concrete Base

Demolished concrete is a valuable resource material that can be suitably recycled back into various construction materials.
Using recycled concrete in your next construction project eliminates the need for demolished concrete being disposed of at
council land fill sites, which assists in protecting the environment from further degradation.
