Is stone dust better than sand?
The compressive strength of concrete from stone powder showed 14.76% higher value than that of the concrete made of normal sand (Mahzuz et al., 2011). It is found that the compressive and flexural strength of concrete made of Quarry Rock Dust are nearly 10% more than the conventional concrete (Suribabu et al., 2015).
How thick should stone dust be under pavers?
It is important to have a MINIMAL of a 4 inch deep, packed sand base (recommend more if you have alot of clay in the area). That will allow you the room for movement and shifting.
Should I wet stone dust before compacting?
Stone dust To fill bigger gaps. Wet it so it compacts properly in between the pavers. Keeps moisture so will favorise the growth of green moss between the bricks.

Do weeds grow in stone dust?
Like organic mulch, a 2-3” layer of stone is required to prevent weeds. Dust and dirt also settle between rocks that ultimately allow weed seeds to germinate. Stone can also be hard to keep clean when leaves become trapped between the rocks. It also draws considerable heat into the soil which is tough on plants.
Which is better stone dust or polymeric sand?
Polymeric sand is indeed pretty good on these fronts. But tiny cracks do form, and weeds will get in there, roots will grow, cracks will get worse. What I use is stone dust AKA screenings. First, lay a foundation of compacted stone aggregate, then lay individual flagstones using screenings as the leveling agent.
What kind of stone is polybind stone dust made of?
Polybind Stone Dust is a unique mixture of polymer binders and calibrated stone available in Tan, Grey. Once Polybind Stone Dust sets, it becomes very firm and locks between the wetcast or natural stone joints while still retaining flexibility and providing a long lasting, durable jointing material.
Which is the best stone dust to use?
There are stone dusts available out there, including natural stone dust, but problems with stability can occur if the dust is not specially treated. You’re better off going with a specially formulated dust like Gator Dust™that, when set, maintains its stability.
Why does polybind stone dust detach from wetcast stones?
PLEASE NOTE: Polybind Stone Dust becomes very firm but will detach from wetcast or natural stones if the crushed stone base has excessive movement. It will also detach from the wetcast or natural stones if the wetcast or natural stones are oscillating back and forth due to improper installation.
