Replacement of gravel or sand most often occurs in situations where they are exposed, as in your gravel driveway or your kids' sandbox. Gravel washes out with heavy weather, and most people with gravel driveways know to replenish the rocks every few seasons. Sand gets used by cats, but it can also wash away.

The power of crusher dust. Crusher dust, also known as quarry dust, is a byproduct of the crushing process in quarries and stone crushing plants. It consists of small, angular particles that range in size from fine powder to 4mm. The particles are created as stone is mechanically crushed, resulting in a mixture of fractured stones and fine dust.
