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.

One of the best base materials for a floating deck is a layer of gravel or compacted paver base to promote drainage and stability. Additionally, using concrete deck blocks or similar supports helps evenly distribute the weight and keep the structure level. These base materials help minimize moisture buildup, reducing shifting and rotting.

If you're only working with a gravel pad, and there is no concrete foundation, you might be able to upgrade to a concrete slab, but you’d have to speak with a professional concrete expert to confirm and get pricing. If you have a concrete foundation or cement block walls around the area where you want to build flooring, you might be able to pour a new concrete floor over the existing one to forgo repairs. Again, speak with a concrete expert or foundation company to see if this is an option.

If you don’t put gravel under concrete, the concrete can crack, sink, bow, or crumble. Even the concrete forming process will not go as smoothly if you are working directly on the soil or bare bedrock. The lack of a proper gravel layer can also lead to drainage issues below your slab, leading to water issues throughout your lawn and around your foundation.
