Stone dust poses some well understood threats to the physical integrity of paver projects. Water retention is one, and a pH level that can steadily eat away at the pavers themselves is another. These are objective material properties that can't be refuted, certainly not with anecdotes.

Trials have shown that rock dust improves soil pH, water retention capacity, microbial activity, root-to-shoot ratio, plant health generally, seed germination rates, and the humus complex, while it increases plant height and weight and reduces plant mortality. Rock dust makes a good replacement for sand in growing media, they found.

Jan 01, 1994Conclusions (1) The presence of stone dust in sand causes opposing effects on the strength of mortars. The first effect is negative, as it increases the water demand; while the second, the filler effect, is positive. Depending on the magnitude of both, stone dust may be favorable or unfavorable to mortar strength.

11.03.2021Patios made with stone dust often shift – this happens because water gets trapped in stone dust when it is broken down from its initial stone format. Stone dust also creates pavers that drain poorly, which is particularly problematic in environments with plenty of rainfall. Not all forms of stone dust are equally troublesome, however.

Jan 29, 2018Due to its nonporous, sturdy surface, it not only protects the base of the area from moisture, thus preventing mold growth, but it also effectively prevents grass and weeds from springing up between the pavers.
