In contrast to stone dust, concrete sand provides superior performance over time. It doesn't eat away at pavers, it affords excellent drainage, and it compacts well.
It is designed to stabilize wider paver joints than polymeric sand. Depending on the paving stone design or job specifications, Gator Dust polymeric stone dust will be your very best choice to secure pavers in place for years, and prevent sprouting or soil erosion.
Stone dust is widely used as a setting bed for any of the various types of stone pavers (flagstone pavers such as bluestone being an example) used by homeowners in small projects.
Crusher dust is cheaper than sand, both in small packages and when purchased in bulk. As the material works well as a base for pavers, it's an affordable and effective alternative to sand. However, crusher dust can vary between batches, with some being far finer than others.
The paver bed is usually made of sand, 1/4″-10 crushed gravel, or synthetic material, and is the topmost paver support layer keeping pavers in place.
A GRAVEL BASE LAYER BEFORE SAND IS A MUST! Using sand alone to set pavers is not enough. The best and recommended paver base is 3/8-inch crushed gravel. The gravel provides a flexible base that absorbs ground tension to prevent frost heaves.
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.
Stone dust is commonly used as a substitute for sand in construction projects, as it is a cheaper alternative and provides similar structural support.
The study has present that crushed stone dust can be used as readily available solid waste as an alternative to natural sand in cement concrete construction work and it can reduce the cost of material and construction cost and can helpful to mend the environment issues.
Higher Water Demand: Stone dust has a high surface area and can absorb more water than sand, which can lead to a higher water demand in the mix. This can affect the workability and strength of the concrete if the water-to-cement ratio is not properly adjusted.
Stone dust is a much darker and coarser version of sand. Much like sand, it is produced in a quarry by running stones through a crushing process — the only difference being that the process is much shorter.
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.
Stone dust is a waste material obtained from crusher plants. It has potential to be used as partial replacement of natural river sand in concrete. Use of stone dust in concrete not only improve the quality of concrete but also conserve the natural river sand for future generations.
When installed improperly, polymeric sand will ruin your hardscape. Polymeric Sand has many benefits, however, the biggest drawback is that it can be easy to mess up, especially if you don't follow the manufacturer's instructions.
Does stone dust get hard? Yes, it does and this is one of the reasons people use for wanting to apply it in their installations. But this is not a good reason to use it. Stone dust does not drain well, keeping water sitting above it and below the product installed while the water very slowly if ever drains through.
One ton will cover Approximately 90 sq ft at a depth of 2 inches when compacted.
Crushed Stone & Stone Dust
Under patio stones and interlocking: Add 4″-6″ of 7/8″ crushed stone for a base and then compact it with a hand or machine tamper. What is more beneficial is compacting the crushed stone in lifts, which means that you would add 2″-3″ of 7/8″ crushed stone and then compact it.
What is Polymeric Sand? Polymeric sand is a material used to fill paver joints, the empty spaces found between each paver, tile or natural stone.
While stone dust and screenings are inexpensive and popular, they don't allow moisture to travel through a paver application. In fact, these materials act like a sponge, holding water in (which essentially keeps the pavers wet).
Joint stabilization – If you don't have sand in the joints, rain water or pool water will run between the brick paver joints, and wash out the base aggregate sand material your brick pavers float on, (usually a 1.5” – 2” sand base) making your brick pavers loose, wobbly, uneven, sunken in or even raised up in some ...
Concrete sand is the proper sand for laying a foundational base for a concrete paver installation. It is extremely coarse sand so it can be compacted uniformly and allows for adequate water drainage. Concrete sand will lift slightly into the joints of the pavers when they are being leveled, locking them into place.
Crushed stone by itself is a common paver base. It's a solid option and provides good drainage. You want to make sure you get the right aggregate for your paver base with crushed stone. Another good choice for your paver base is recycled concrete aggregate or RCA.
Paver sand holds the pavers in place and allows you to adjust them. The final paver sand depth needs to be 1 inch and you need to account for sand filtering into the paver base and into the joints between the pavers.
To achieve a firm base from the beginning, you need to make sure you have the correct depth of sand under pavers. We recommend allowing for a depth of at least 30mm loose sand. This will pack down to about 20-25mm depending on the method you use for packing and will allow for drainage without your pavers shifting.
