Our 20/40mm single size gravel, also known as 20/40mm shingle, is a premium primary aggregate compliant with Type B specifications. This makes it the perfect solution for bulk backfilling, ground drainage systems, and water management infrastructure during civil engineering or construction works.
It can also be utilised as a reliable sub-base lining or bedding layer for large pipes, as its coarse, uniform texture allows water to flow freely, preventing pooling and safeguarding your underground utility installations.
