804 stone is the go-to sub-base for almost any hard landscaping or construction job. A well-graded crushed limestone running from fine dust up to 40 millimetres, it compacts down into a tough, stable, free-draining foundation that won't shift once it's laid. Ideal for: Sub-base under driveways, patios, paths and garden sheds Foundations and footings Yard and road bases Backfill around drainage and pipework A solid bed under tarmac, paving slabs or concrete Why it works: The mix of particle sizes is the whole point — the fines fill the gaps between the larger stones, so when you compact it with a plate compactor it locks together into a hard, level surface that carries weight and drains well. How to lay it: Spread in layers of roughly 100 millimetres, level it off, and compact each layer with a plate compactor before adding the next. Lightly dampening the stone helps it bind as it goes down. Supplied in a tonne bag 0.614m³
