20mm Blue Metal is a natural aggregate that is commonly used for drainage in many different fields. Its many uses include backfilling trenches, around PVC and Ag-Pipe, for drainage behind retaining walls and even as a base for concrete and deep garden beds to promote drainage.
20mm Blue Metal is often used for mixing concrete due to its high compressive strength, and can also be a cheaper alternative as a decorative dressing for footpaths and driveways.
20mm Blue Metal is available in 30kg bags and by the tonne.
