Gravel in Marathon, FL

Prices in Marathon vary by gravel type and local availability, but expect roughly $35-$90 per ton delivered for common materials (crushed rock, pea gravel, crushed shell). Hello Gravel has a 3-ton minimum order, so material cost for a minimum order typically starts around $105-$270 before any local delivery fees or taxes. Exact pricing and any site-specific delivery charges are shown at checkout when you enter your Marathon zip code.

Crushed limestone and properly graded crushed rock with a clearstone base resist washout and compact well in Marathon’s conditions. Crushed shell is popular in the Keys for appearance and drainage, but it wears faster and may need more frequent top‑ups; pea gravel drains well but can migrate in heavy rain unless restrained. Choose a heavier, angular stone for driveways and use shell or pea gravel for decorative areas or walkways.

Yes — many local suppliers and haulers deliver to Marathon and the surrounding Keys. Delivery fees can vary; Hello Gravel will show any additional mileage or access charges at checkout. Because Marathon is on the Overseas Highway, most deliveries do not require ferry service, but remote or restricted sites, limited truck access, or late delivery windows can incur extra fees.

For a two‑car driveway (about 20 x 20 ft = 400 sq ft), plan on roughly 3.5 tons for a 2u0022 layer, 5.2 tons for 3u0022, 6.9 tons for 4u0022, and about 13.8 tons for a 6u0022 compacted base (using ~1.4 tons per cubic yard). If your driveway is 10 x 20 ft (single car/shorter length), roughly half those amounts apply. For durable driveways in Marathon you’ll usually want a compacted base of 4–6u0022 plus a 2–3u0022 finish layer, so most homeowners order 8–14 tons for a standard 20 x 20 driveway.

Use a geotextile fabric over the native sand, then install 4–6u0022 of DOT‑style crushed base (angular, 3/4u0022 minus or similar) compacted in 2u0022 lifts with a vibratory plate compactor or roller. Crown the drive slightly and provide edge restraints or curbing to stop lateral migration; add a 2–3u0022 finish layer of 3/4u0022 clean stone or stabilized shell on top. Proper grading, good drainage (swales or French drains), and solid compaction are the best defenses against washouts during heavy rains and hurricane season.

In Marathon’s salty, rainy climate a well‑built gravel driveway can function for many years, but top layers typically need replenishing every 2–5 years and more often after major storms. Expect routine maintenance like raking, regrading low spots after heavy rains, adding 1–3 inches of fresh material as needed, and re‑compacting annually or after storm events. Inspect and repair drainage features before hurricane season to reduce damage.

Permit and HOA requirements vary by location, so check both the City of Marathon or Monroe County building department and your HOA before starting work. Driveways that alter the public right‑of‑way, stormwater flow, or coastal setbacks may need permits or engineering sign‑offs. When in doubt, contact local authorities or Hello Gravel’s team and we can point you to the right local contacts.

Gravel is the lowest‑cost option up front, drains well, and is easy to repair after storms, but it requires more frequent maintenance and top‑ups. Asphalt and pavers cost more initially and may hold up longer under traffic, but asphalt can soften in heat and exposure to salt and may need more intensive repairs if undermined by flooding. Choose gravel if you want lower upfront cost and easier storm recovery, or choose asphalt/pavers for a longer lasting, lower‑maintenance surface if budget allows and proper drainage is provided.

Crushed shell is a natural, local choice in the Keys that looks authentic, drains well, and fits the coastal aesthetic, making it great for walkways and low‑traffic landscaping. For driveways, crushed shell can work but tends to break down faster and may require more frequent replenishment; combining a crushed‑stone compacted base with a shell finish gives the best balance of stability and appearance. For heavy loads or steep/erosion‑prone sites, use angular crushed stone for the base to minimize migration and washout.

Contractors can source DOT‑spec base and driveway stone from local suppliers listed through Hello Gravel or from regional aggregates yards that serve Monroe County; ask for materials that meet FDOT or Monroe County specs and for delivery tickets verifying gradation. Bundle hauling with spreading, compaction, geotextile placement, and grading services for a complete install; getting hauling and compaction included reduces coordination and helps ensure the material is placed and compacted correctly for local conditions.
