Mason Sand for Patios in Unionville, MI

Gravel and aggregate delivery in Unionville, MI runs on the working season. Base, driveway and paver work starts after the spring thaw and continues into late fall. Frozen ground stops compaction, and frost laws limit heavy trucks on many roads during the thaw. Michigan Rock Supply delivers 21AA limestone, sand and stone to Unionville and the rest of Tuscola County.

Unionville sits on flat former glacial lake bed ground. Most of it is clay, silty clay and clay loam, and most of it drains poorly. Water stands in low spots after snowmelt and heavy rain. That shapes what you put under a patio.

Ground and Conditions in Unionville

A thin base under pavers shows its problems fast here. The surface rocks, joints open, and low corners hold water after a spring rain. The cause is usually the ground below, not the pavers.

Clay holds water instead of passing it. When frost comes out of the ground, that water is trapped in soaked soil, and thin bases soften and rut. Frost depth in Michigan is 42 inches under the Michigan Residential Code. That is a footing depth set by the building official, not a target for a gravel base.

For a patio, the practical answer is a compacted base with a bedding layer on top, plus a way for water to leave. On flat, slow-draining ground, water needs somewhere to go. A drainage layer or a run to a ditch or tile line keeps the base from sitting in standing water.

Materials for Unionville Projects

Patio and flatwork work starts with what goes under the pavers. Bedding sand and fine stone set the surface. The base below them carries the load.

Mason Sand is the standard bedding sand for brick, block and paver joints. Screened and consistent, it beds pavers and fills joints. Stone Screenings do the same job for flagstone and patio bedding, and they top a compacted base with a fine, tight layer.

Under the bedding, 21AA Limestone is the Michigan driveway base. It compacts hard and carries pavers, parking pads and pole barn floors. 22A Road Gravel is a different class, a hard-packing mix of stone, sand and fines for unpaved drives and private roads. It is not a drainage material.

Where water has to move, Drain Rock handles French drains, drywells and downspout runs, including in slow-draining clay. #57 Stone covers drainage beds and concrete aggregate. For a finer washed option, #89 Crushed Stone fits paver joints and tight bedding.

Delivery to Unionville and the Surrounding Area

You order online and choose a quantity by the ton or by the yard. If you are not sure which one your project needs, the calculator sizes the load for you. Pick a delivery date at checkout, and a dump truck brings the material to your site.

Bulk delivery means the truck has to reach the spot where you want the pile. On flat ground with soft shoulders, a loaded truck needs firm footing. If your drive is unpaved and the thaw is on, plan where the truck can set down.

Michigan Rock Supply delivers across Tuscola County, including Caro, Vassar, Cass City, Reese and Mayville. Unionville sits in the Thumb, where spring snowmelt and heavy rain on flat, slow-draining clay keep ditches and tile drains busy.

Questions About Gravel and Sand in Unionville

What gravel is best for a driveway in Unionville?

For most drives, 21AA limestone is the base. It is the standard Michigan driveway base, a crushed limestone with fines that compacts hard. Top it with driveway gravel for the wearing surface. If you want a hard-packing mix for an unpaved drive or private road, 22A road gravel is the other class to consider. Neither one is a drainage material, so handle water separately.

How much material will my project need?

Use the calculator to size the load. Enter your project dimensions and the depth you plan to build, and it returns a quantity by the ton or the yard. That keeps you from over-ordering or running short mid-project. If you are bedding pavers, order the sand and the base stone together so both arrive for the same work window.
