Crushed River Gravel 5 & 7mm

Crushed River Gravel, also known as 5mm or 7mm CRG, are natural products used for backfilling trenches, around PVC and Ag-Pipe, and for drainage behind retaining walls. One of the main uses of 5mm and 7mm CRG, is as a drainage layer for Bio-Retention Pits, also commonly known as Rain Gardens.

These products can also be used for a base underneath concrete and can even be blended into concrete mixes due to their high compressive strength.

5mm and 7mm Crushed River Gravels are available by the tonne.
