Stone dust is a fine material that absorbs moisture readily, then releases it slowly. The same properties that work wonders for organic gardening can wreak havoc underneath pavers, causing efflorescence and allowing them to settle or shift easily under load. In extreme frost-thaw cycles, water-soaked stone dust can actually pump up through the ...

If un-compacted, or poorly compacted, soil or fill sinks under a slab you end up with a hollow spot. If you drive on this concrete and apply pressure to it, the concrete tries to bend or stretch to conform to the hollow spot. The result is almost always a crack and the concrete slab drops down. I see photos of this unnecessary damage all the time.

Unlike pea gravel or sand, crushed stone has angular edges that lock together and prevent "rolling", thus creating a solid base for your project. Also, for areas with drainage problems, crushed stone will stay in place while smaller sand particles tend to wash from beneath the stone. This creates voids that can compromise the stability of ...

Crushed stone aggregate materials are commonly used for basal embankment support on soft subgrades or for horizontal drainage in soft soils. When the drainage material is constrained by earth pressure and water pressure, it changes to an unsaturated water-permeable state. If the pore water pressure decreases as the compaction of the soft ground increases, the water does not drain through the ...
