Mason Sand for Patios in Ollie, IA

Planning a patio, a paver walkway or a shed pad means gravel and aggregate delivery in Ollie, IA, and Iowa Rock Supply brings it to your site. Most flatwork around here starts with Class A roadstone under it.

On the Southern Iowa Drift Plain, the ground below that base is old till under a loess mantle, and it does not drain well.

Ground and Conditions in Ollie

Across the Southern Iowa Drift Plain, the subsoil is a heavy grey clay that shed water rather than takes it. Rain perches on top, runs off, and leaves the low end of a grade soft.

That is where a thin base shows itself first.

A paver patio set on too little stone moves, tips and pumps fine material up through the joints. The fix is a base that spreads the load instead of letting it sit on clay.

Class A roadstone is built for that job, because the fines left in it bind and compact into a firm, tight crust.

This is also the most eroded landscape in Iowa, and spring rain on saturated clay is the worst of it. Add repeated freeze-thaw, and gravel lanes heave every spring.

That is a reason to get the base course right the first time. A wet spring also pushes base work back several weeks, since clay has to dry before anything gets compacted.

Materials for Ollie Projects

Bedding is what holds pavers flat, and the material you bed them in matters as much as the base under it. Limestone screenings are the go-to bedding for pavers and flagstone, and they also fill the joints once the units are set.

They are a fine, 3/8 inch minus product that packs smooth.

Below the bedding, Class A roadstone carries the load. It is the standard crushed limestone base course for driveways, parking pads, shed bases and farm lanes.

Where a drive is new, or a soft spot needs extra strength, 1 inch roadstone goes down first as a coarser layer.

For drainage and wet corners, clean rock comes into play. It is washed and open graded, so water moves straight through it, which suits subdrains, pipe bedding and backfill behind retaining walls.

Where a patio sits against a slope, that open stone is what moves water away from the base.

Washed sand beds and levels slabs and pavers, and mason sand handles brick and block mortar and paver joints. Both are clean, free draining products that belong under flatwork.

Questions About Gravel and Base Work in Ollie

What gravel is best for a driveway in Ollie?

Class A roadstone is the standard base course here. It is crushed limestone with the fines left in, so it binds and compacts into a firm surface for driveways, parking pads and farm lanes.

Where a drive is new or carries heavy equipment, 1 inch roadstone goes down first as a coarser layer, with a finer course on top. On the clay ground of the Southern Iowa Drift Plain, a well-built base is what keeps a drive from going soft.

How much material will my project need?

Quantity depends on the area you are covering and how deep you want the material. You order by the ton or by the yard.

Each product page has a calculator you can use to size the load before checkout. When the numbers look close, it is worth checking them again before you order, since the amount you pick at checkout is the amount that arrives.
