An alternative to simply using gravel over the existing soil is to use flexible plastic porous pavers. Porous Pavers are designed to allow organic material such as aggregate or grass to replace traditional hard surfaces such as concrete or asphalt. By installing these flexible porous pavers over a base course, they stabilize the surface, absorb ...

Take a hose and drench the entire area. The pressure should be strong enough that it can loosen dirt and debris, as well as remove weaker stains. Take care, though, that it is not too strong — we will explain why later. The goal is not simply to take out whatever is easy to take out but also to saturate the surface.
