The stones do not work well on uneven ground. If the stones are not buried into the ground and made level upon installation, they almost certainly will shift or crack on uneven ground. Additionally, rainwater or water from sprinklers can run under the edge of an uneven paver, causing erosion. In a freeze and thaw cycle, trapped water under the paver can cause the problem to worsen by shifting the stepping stones around. Use a bubble level to make sure the ground under each paver is as even as possible, even if the nearby ground is uneven.

Think of the street as a way to capture all the elements on either side of the road, including the road—a street encompasses the homes or other buildings, the trees, and the road of a given area as defined by the beginning and end of the street on a map. A roadway, however, is the component of the street where cars travel.

Decomposed granite and caliche can both harden into a solid surface using a plate compactor. However, due to decomposed granite’s fine particles, it’s not suitable for driveway surfaces. Some homeowners use pea gravel mixed with a gravel-binding resin to bind the loose stones and create a solid surface that won’t shift like loose gravel.

Professional installers often include a deep layer of crushed gravel under permeable pavers to allow more runoff to soak through into the soil below. Many installations will include multiple layers of gravel, with coarser aggregate at the base and finer aggregate that sits on top of that bottom layer. Above the gravel, you’ll often find coarse sand that helps reduce paver shifting over time. Some permeable paver designs include a water collection system set into the gravel layer to route runoff to a safe area for disposal.
