Recycled Drainage Gravel 20mm

Recycled Drainage Gravel 20mm is a coarse granular material used where the project calls for durable stone and suitable drainage or fill performance.

Uses on a job site

• Drainage trenches and aggregate around suitable drainage pipe.
• Drainage backfill behind retaining structures where the design specifies it.
• Site drainage layers and landscape drainage works using the nominated grading.

Material properties

• Nominal 20mm size; check the current grading for specification work.
• Spaces between particles allow water movement when fines content is suitably controlled.
• Processed recycled material; colour and composition may vary.

Before you order

Use filter fabric and pipe protection where specified. Confirm grading, fines content and suitability for the drainage system or engineering design.
