Before your Cardiff delivery arrives

Bulk bags are usually lifted off by crane where access allows; tell us where they can sit and whether the ground is firm. Cardiff is inside our standard mainland delivery area.

• Clear a level area for pallets, ideally on boards, so materials stay out of standing water.
• Have someone on site for the delivery if you can, or agree a safe drop point with us in advance.
• On busy streets in Cardiff, a parking suspension or a quiet time slot can make offloading safer, so tell us about local restrictions you know of.

Choosing ballast and gravel

Gravel size

20 mm gravel suits concrete and drainage layers; 10 mm and pea gravel suit bedding pipes and paths.

Decorative areas

Lay decorative gravel over a weed membrane and a firm base so it does not sink.

Ballast & Gravel questions

How much gravel do I need for a path?

Multiply the area by the depth (often 40 to 50 mm for decorative gravel) to get cubic metres, then allow about 1.5 tonnes per cubic metre.

Can you deliver ballast and gravel to a site with restricted access in Cardiff?

Usually, yes. Tell us about the access when you ask for a price and we will plan the vehicle and offload, or say if a smaller vehicle is needed.
