What is 304 limestone and what is it used for in Marion County?

304 limestone, also called #304 stone, is the standard Ohio base stone. In Marion County it goes under gravel drives, parking areas, shed floors and asphalt. Spread and compacted in lifts, it builds the load-bearing layer that keeps a surface from rutting over clay.

How much gravel do I need for my project?

Use the calculator on the product page. Enter your length, width and the depth you plan to place, and it returns a quantity you can order by the ton or yard. That works for a driveway base, a parking pad, a drainage bed or a decorative layer over fabric. Pick your delivery date at checkout and the truck brings it to your site.

Marion County 304 Limestone and Gravel Delivery, OH

Q: How deep should a gravel driveway base be in Marion County?

Depth depends on your soil, your traffic and how the site drains. Clayey till drains slowly here, so a compacted base and a clean stone drainage layer matter. Frost depth is 32 inches in Columbus and Dayton, set by each local building department, so confirm footing and post depth with your building official. Use the calculator to size the load once you settle the depth.

Ohio Rock Supply handles gravel, stone and aggregate delivery in Marion County, OH. Most jobs here start with 304 limestone, the standard Ohio base stone. It goes under drives, parking pads, shed floors and asphalt. The county sits on clay loam and silty clay over gently rolling ground, so the base you put down matters more than the surface stone on top. Order online by the ton or yard, then pick a delivery date at checkout.

Materials Delivered in Marion County

Base material comes first because everything else sits on it. Spread and compacted, it builds the load-bearing layer for a drive or a parking area.

Above the base, Ohio suppliers sell 411 limestone for the surface.

Clean stone is sold by number here, not by inch size. The table below shows the sizes we deliver and what each one is good for.

Sand and soil round out most orders. Washed sand beds and levels under slabs, mason sand works into brick and block joints, and screened topsoil rebuilds a lawn over clay subsoil. Natural Pea Gravel, river rock and shredded mulch cover the decorative side.

Ground Conditions Across Marion County

The working season drives the schedule here. Base, driveway and paver work starts once the ground thaws and the flats dry out in spring, and it runs into late fall. Frozen or saturated clay will not compact well, so a load dropped on wet ground in March often sits until the site dries.

Clayey till drains slowly. Water ponds in flat swales and low spots after spring rain and snowmelt until ditches or tile clear it. That slow drainage is why a compacted base and a clean stone drainage layer matter on nearly every job. Sand and gravel in the larger river valleys drain quickly by contrast.

Cold winters bring repeated freeze and thaw. That heaves wet clay under drives and patios and lifts shallow posts and pads. Frost depth is 32 inches in Columbus and Dayton, set by each local building department, so check with your building official on footing and post depth.

Erosion follows heavy rain. Stream and ditch banks scour, bare graded soil washes, and steep river valley sides slump. RipRap on banks and outlets handles most of that, and #4 stone works well on trench bottoms and soft entrances.

Choosing the Right Material

Ground next door is close to what you work with in Marion County. Delaware County and Union County sit in the same till plains zone, with the same clay loam and silty clay over rolling ground, low moraine ridges and sand and gravel in the river valleys. Crawford County shares that ground too, so the base and drainage choices carry over between all four.

That means the difference is usually the project, not the soil. A driveway in Delaware County built over clay takes the same 304 limestone base and 411 topping as one in Marion County. A drainage run in Union County wants the same clean stone, #57 or #8, set in a bed that lets water move.

Where the ground shifts is at the valley edges. Sand and gravel drain fast, so a base there sheds water sooner and holds up well. Clay swales hold water longer, so a thicker compacted base and a clean stone layer under the surface keep the drive from rutting after spring rain.
