-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.
-20mm recycled concrete base can be supplied to;
- Institute of Public Works Engineering Australia (NSW) – IPWEA Class R1 and R2 as guided by the “Specification
for Supply of Recycled Material for Pavements, Earthworks & Drainage” Issue No. 3.0 April 2010.
