Stone Dust

Stone dust, also called crusher dust or grit, is the fine by-product of rock crushing. It compacts tightly, drains reasonably and costs less than sand, which makes it the standard bedding and filling material on Indian sites.

It is not a straight substitute for concrete sand — the grading is different and the fines content is higher — but for bedding, filling and paver jointing it is often the better and cheaper choice.

Typical units: tonne, cft. Cheapest of the fine aggregates; freight is usually the dominant cost.

• Bedding layer under paver blocks and tiles
• Joint filling for interlocking pavers
• Plinth and trench filling
• Sub-base levelling
• Non-structural mortar and blockwork where permitted

Standard crusher dust for bedding and filling.

Washed grit

Reduced fines, closer to M-sand, usable in some mortars.

• Check the clay and fines content — excessive fines hold water and cause settlement under paving.
• Buy by weight; stone dust compacts and its loose volume is unreliable.
• Confirm the parent rock. Dust from hard granite or basalt performs better than soft limestone dust.
