Crusher machine for gravel and aggregate faqs

1. What is the average coverage per ton?
A good rule of thumb is that one ton of sand or gravel (1‐1/4” or smaller) will cover an area of 100 square feet at a depth of two inches*. Coverage decreases as the size of the aggregate increases.

2. What is Crusher Run?
Often called 21A or #26, Crusher Run is a crushed gravel that has “fines,” or granite dust, mixed in.Crusher Run packs well and is ideal for driveways or as a substrate to create a level base for patios,walkways and retaining walls.

3. Which gravel should I use for a French drain?
#57 clean stone is commonly used for driveways and French drains. Water flows well through it, and the pieces are large enough so that they won’t fall through the drainage holes in the pipe used for this type of drain.

4. What is the difference between masonry sand & coarse “concrete” sand?
Masonry sands have a fine consistency and are mixed with mortar or cement. The fine grains also make it a good choice for children’s sandboxes or to put underneath the liner of an above‐ground pool.Coarse sand is very much like beach sand. Applications vary, but it is used largely as the second layer(on top of the Crusher Run) in the base of a patio or walkway.

5. I expanded a dry creek bed that I installed last year and the color of the gravel doesn’t match. Why?
Gravels and other aggregates are natural products, therefore the color, size and texture will vary each time the stock is replenished.

6. Besides driveways, drains and as a basis for patio construction, in what other ways can I use gravel or aggregates for landscaping?
Depending on the size of the aggregate, you can use them in dry creek beds, waterfalls, as garden accents, borders and for dog runs. Use larger river rocks under the eaves of your house to limit runoff and in low spots to reduce standing water. Carefully placed aggregates can reduce or eliminate erosion in areas with heavy water flow. Aggregates are inexpensive and have a variety of functions from practical to cosmetic.
