About Our Rock Salt, Grano & Tarmac

We supply a comprehensive range of rock salt, grano, and tarmac aggregates for groundworks, surfacing, and winter maintenance projects.

This selection includes bulk bags and smaller 25kg options to suit site requirements of any scale. From gritting access roads and car parks to laying drivable surfaces and creating solid sub bases, these materials deliver the coverage and compaction that trades and DIY users rely on.

Our Selection of Rock Salt, Grano, and Tarmac

Our rock salt, grano, and tarmac range covers the essentials for roadways, driveways, and pathways. Rock salt is available in bulk bags for large scale winter gritting, fantastic for site managers and contractors maintaining safe access during cold weather.

Grano dust, also known as granite 4mm dust, provides a stable bedding layer for block paving and flag installation. This fine material locks pavers into position and prevents shifting under load. We stock both 25kg bags for smaller residential work and bulk bags for wider commercial jobs.

Tarmac materials and clean granite chippings work well for decorative surfacing and permeable driveways. Our 6mm and 20mm granite options come in grey tones, suitable for borders, drainage channels, and landscaping features. Cloburn red granite sand offers an alternative finish for pointing or decorative top dressing.

These products suit groundworkers, landscapers, and property maintenance teams who need consistent material quality and straightforward ordering. To view more products, explore our aggregates range.
