Under Deck

The space under your deck doesn’t have to be wasted. It can be turned into a patio, a hangout space, or a storage space. If you have a wooden deck, consider having gravel under the deck area to promote drainage and prevent water damage. We also offer wood chips and concrete for under decks if you want a different material.

If you’re still unsure what to do with your under deck area, contact us for help. If you’re considering having a gravel under deck area, but still aren’t sure, read our complete guide to adding gravel under your deck article for more information.

FAQs

To maintain the gravel under your deck, you’ll need to do a few things, including regularly raking it, weed control, and inspecting drainage. We’re happy to help you maintain any under-deck area we put in for you. Contact us if you’re having any trouble with drainage or weeds.

In general, a thickness of 4 to 6 inches is recommended for effective drainage, prevention of moisture buildup, and the creation of a stable base. However, the exact thickness will depend on soil conditions, drainage requirements, intended use of the area, and local building requirements.

Gravel is a great option for your under-deck area. It provides excellent drainage, which is especially important if you have a wooden deck, as it prevents moisture damage and rot. It also can help prevent erosion in areas with poor soil conditions and make it easier to access your under-deck area by creating a level surface.

Putting a material like concrete or gravel will help keep your under-deck area dry. You can also include a weed barrier fabric topped with gravel to promote drainage and prevent water buildup.

The best gravel under your deck depends on climate, drainage needs, and personal preference. We offer both pea gravel and crushed stone, which promote drainage and aesthetic appeal.
