The most obvious disadvantage of permeable paving is that the cost is typically higher compared to non-permeable concrete, pavers, or asphalt methods. Also, the porous material can get clogged with dirt and debris, requiring cleaning and power washing more frequently than standard paving materials and methods. Although permeable paving is not ideal for highways, airports, and other surfaces supporting heavy traffic and machinery, it is suitable for regular residential driveways.

Yes, it is possible to pave over an existing driveway, but whether it's the right choice depends on several factors. If the underlying structure of your current driveway is still strong, concrete or asphalt resurfacing can be a cost-effective way to prolong its life. However, if your driveway has significant issues like potholes, deep cracks, or other inconsistencies, it is best to remove the old driveway and start from scratch. Key factors to consider include the current driveway's condition, the compatibility of the new material, the added thickness and height, and the necessary surface preparation.

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.

The ideal distance between stepping stones depends on your design preference. A general rule is to place them about 24 inches apart from center to center to match an average person's stride. Another common approach is to leave about 6 inches of space between the edges of each stone; this can be adjusted to fit the path's total length without cutting pavers. If you plan to plant between the stones, leave at least 6 to 8 inches of space to give the plants room to grow.
