Mason Sand for Patios in Cantril, IA

If you are planning a patio, a paver walkway or a shed pad in Cantril, IA, the order usually starts with gravel and aggregate delivery in Cantril, IA. Iowa Rock Supply sells the bedding material and the base course that go under flatwork, plus the Class A roadstone that carries the load beneath them.

Under a paver patio, bedding is what you actually feel underfoot. Get it right and the pavers sit flat for years.

Ground and Conditions in Cantril

Across the Southern Iowa Drift Plain, old till sits under a windblown loess mantle. Beneath both is a thick grey clay that water will not move through.

That clay is why a thin base fails here. Water perches on it, runs off, and leaves ground soft at the bottom of a grade.

Pavers bedded shallow over clay start rocking within a season. The bedding washes out at the low edge, the joints open, and the surface cups where traffic crosses it.

The fix is a compacted roadstone base under the bedding, plus a clean stone layer where water needs somewhere to go. Spring rain on saturated clay is the worst of it, so a wet spring pushes base work back several weeks until the ground dries.

This is Iowa's most eroded landscape, with deep-cut streams and gullies after heavy rain. That is why rock also goes in on slopes, culvert outlets and stream banks.

Materials for Cantril Projects

Bedding is the material directly under pavers or flatwork. Limestone screenings, also called screenings or 3/8 inch minus screenings, are the standard bed here.

They are crushed limestone with the fines left in, so they compact and hold a paver flat instead of shifting under it. Use them for paver and flagstone bedding, joint filling, and a fine top dressing over a compacted roadstone base.

Class A roadstone, also called roadstone, 3/4 inch roadstone or road rock, is the base that goes under the bedding. It is crushed limestone with the fines left in, so it binds and compacts.

Class A roadstone suits driveways, parking pads, shed bases and farm lanes.

Where the ground is soft or the lane carries heavy equipment, start with 1 inch roadstone, also called 1 inch minus or 1 inch road rock. It is the coarser grade and goes under a finer surface course.

For drainage, clean rock, also called clean stone, 1 inch clean or 1 1/2 inch clean, is washed and open graded, so water moves straight through. It backfills subdrains and drainage tile, beds pipe, and goes behind retaining walls.

Washed sand, also called washed fill sand or concrete sand, beds and levels under slabs and pavers. Mason sand, also called masonry sand, is the finer grade for brick and block mortar, paver joints and play sand.

Questions About Gravel and Bedding in Cantril

What gravel is best for a driveway in Cantril?

Class A roadstone is the standard base for a driveway here. It is crushed limestone with the fines left in, so it compacts into a firm surface over the clay subsoil.

Where the ground is soft or the lane carries heavy equipment, 1 inch roadstone goes down first as a coarser base. Top a thinned drive with driveway gravel over the compacted base.
