20mm to Dust Limestone (Bulk Bag)

20mm to Dust Limestone is a graded limestone aggregate containing a continuous mix of particle sizes from approximately 20 mm down to fine dust. This gradation allows the material to compact tightly, making it suitable for base layers and groundwork where stability is critical.

By combining larger stones with finer particles, this product creates a stable, interlocking mass that is ideal for:

• Sub-bases beneath slabs, patios and hardstanding

• Groundwork and reinstatement layers

• Compacted bases for driveways and pathways

• Blinding material to level a surface

20mm to Dust Limestone is supplied in bulk bags or loose loads depending on access and quantity requirements.
