What is the difference between crushed stone and gravel?

Gravel is naturally rounded; crushed stone is mechanically broken and angular. Angular material compacts and stays put, rounded material rolls.

Which size is best for a driveway?

10–20 mm angular over a compacted base, with a firm edge. Larger sizes feel loose to drive on.

Can you supply washed crushed stone?

Yes. Washed material is cleaner in the bag and better for drainage applications.

How much crushed stone do I need for a driveway sub-base?

Typically 100–150 mm compacted depth of 20–40 mm crushed stone beneath a 10–20 mm decorative topping, which works out to roughly 200–250 kg per square metre across both layers.

What's an alternative if crushed stone feels too sharp underfoot?

Rounded pea gravel or river pebble in a similar size band, though note it won't compact or interlock the way angular crushed stone does for load-bearing use.

How is crushed stone typically freighted?

As bulk tonnage in 20ft or 40ft containers, loaded loose to maximise payload rather than bagged, since bagging adds cost buyers rarely need for a sub-base material.

Do you inspect crushed stone before it ships?

Yes — each production run is screen-tested against the agreed size band and checked for excess fines or oversize material before loading, against a written tolerance if you specify one.

Can crushed stone colour vary between orders?

Yes, slightly, since it depends on the parent quarry rock. For a phased project where consistency matters, ordering the full tonnage from one batch avoids a visible mismatch later.

Crushed Stone and Angular Decorative Gravel

Crushed stone is what you specify when the surface has to take weight. The angular faces lock together instead of rolling, so driveways stay level and paths hold their shape. We grade and wash it in the size bands contractors ask for.

Angular faces that compact and interlock
Graded and screened to consistent bands
Natural greys, buff, black and multi tones

Choosing a size

10–20 mm is the default for decorative driveways: big enough not to track indoors, small enough to compact. 20–40 mm suits drainage and heavier traffic. 2–6 mm is a binding layer, not a finish layer.

Base preparation

Crushed stone only performs over a compacted, membrane-backed base with edge restraint. Laid straight onto soil it disappears into the ground within two seasons.

Coverage by size band

10–20 mm crushed stone at a compacted 50 mm depth covers roughly 10 square metres per tonne once you allow for compaction loss during rolling — always order 5–10% over the flat-area calculation to cover this. Finer 6–10 mm binding layers are usually specified by depth in millimetres, not tonnage per area, since they're a sub-base component rather than a finish.

Retail versus contractor packaging

Contractors buying by the truckload take bulk tonnage tipped on site; smaller landscapers and DIY buyers are better served by 800 kg–1 tonne jumbo bags with a bottom-discharge spout, which avoids the labour of shovelling loose bulk stone off a driveway.

A frequent mistake on drainage jobs

Specifying washed crushed stone for a driveway finish but unwashed for the sub-base beneath it, when it should usually be the reverse — unwashed material with retained fines compacts harder as a structural base, while the visible surface layer benefits from washing to look clean.

Pre-shipment inspection for graded material

Before loading, we screen-test a sample from each production run against the agreed size band and confirm it is free of oversize or undersize material and excess fines. For washed grades we also check the wash has cleared dust residue. Buyers who specify a written tolerance up front — for example, a maximum 5% outside the stated band — get a batch that matches on arrival rather than a dispute after unloading.

Colour variation across quarry batches

Crushed stone colour depends on the parent rock, and even within one quarry, natural greys and buffs can vary slightly batch to batch. For projects where visual consistency matters, such as a driveway laid in phases, we recommend ordering the full tonnage from one batch rather than topping up later from a different run, since a mismatch is far more noticeable in angular crushed stone than in mixed-tone pebble products.

Behaviour through freeze-thaw cycles

Well-graded, hard crushed stone does not itself degrade in freezing conditions, but a poorly compacted or undrained base beneath it can heave as trapped water freezes, pushing the surface layer out of level. Specifying a free-draining sub-base and adequate depth below the frost line in cold climates protects the finished surface far more than any property of the stone itself.
