The stone or sand underneath the pavers filters the water to the soil below, thus watering the ground. These pavers absorb water much in the same way as grass, dirt, or any other outdoor ground would. Because of this, any water that falls on your pavers is able to easily drain to the soil below.
Does gravel absorb water?
Water moves through gravel a lot faster than it does through the majority of soil and other materials. Since the drainage process is expedited when gravel is used at the base of the water body, puddles and wet areas are able to dry out quickly instead of pooling up on top of soil and other land materials.

It is established that 40% replacement of sand by mine dust gives supreme result in strength compared to normal concrete as well as then decreases from 50%.
Is crusher run good for drainage?
Crusher run is a blended mix of coarse aggregate and fine aggregate. The combination of both crushed stone and stone dust creates a low void content (the amount of space or air between the pieces of rock in a mix) that is valuable in concrete construction for its compaction ability and drainage characteristics.
Will water drain through pavers?

What is a clean stone?
Washed clean stone is essentially crushed stone that has been washed to get rid of any small chips and rock dust. This prevents it from compacting and ensures that it will always have great drainage. Because of this, it’s an ideal choice for bottom and mid-layers, though it does tend to be a bit pricier than non-washed crushed stone gravels.
Where does river rock come from?
Just as the name suggests, the gravel used in river rock comes from the beds of rivers and streams. These stones are round and semi-polished from years of running water. They have a smooth texture, which means they tend not to stay put once you lay them down. However, they’re very attractive stones that are a great choice as a top layer. Just make sure to edge the river rock with another type of stone to keep it all in place.

Crushed stone #411 is another very popular crushed stone option that’s quite similar to crushed stone #57.

The smaller stones and dust fill in the cracks left by the larger stones, causing them to all compact together and form a tight surface. It’s great as a top layer of driveways and other areas that require drainage, though the inclusion of smaller stones and rock dust means it’s not an ideal choice for other layers. Luckily, it does tend to be a cheaper option for the top layer than some of the more decorative river rocks and pea gravel.

Can you use stone dust under pavers?
The Interlocking Concrete Pavement Institute (ICPI), the governing body for best practices in the industry, does not approve of using stone dust under pavers. Their recommendation is to use a coarse-grained sand that complies with ASTM C33 standards. When comparing stone dust vs sand, this sand is definitely an acceptable material to use under pavers. It provides drainage, wont eat away at the pavers, and it compacts well. With the compaction of the pavers, the sand will work its way into the joints of the pavers from below creating that interlock that is required in an interlocking system.
Does ICPI use stone dust?
This may be worded in the warranty as being installed according to the Interlocking Concrete Pavement Institute (ICPI) standards or to the manufacturer’s standards which both include not using stone dust according to their cross-sections or installation standards.
Does stone dust get hard?
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. This causes the next two problems that are listed below, but for those that experience frost-thaw cycles will know that this water will cause a major problem. These cycles will cause shifting, heaving, and sinking of pavers.
