Materials for Granville Projects

Water is the thing that ruins a yard around here, so the washed stone matters. Clean rock and 3/4 inch clean stone are washed and open graded, which means water moves straight through instead of sitting in the pile.

Use Clean Rock for French drains, drywells, downspout runs and septic rock. It also backfills behind a retaining wall, where you want water to reach the tile rather than push on the wall.

3/4" Crushed Stone is the smaller clean option. It works for drive surfacing where a loose, free draining stone is wanted, and for pipe bedding and trench backfill.

For the fines side, Limestone Screenings bed pavers and flagstone, fill joints, and top dress a compacted roadstone base. Class A Roadstone is the 3/4 inch crushed limestone base with the fines left in, so it binds and compacts under a drive, a parking pad, a shed base or a farm lane.

Where a new drive is going in over soft ground, or a lane carries heavy equipment, 1 Inch Roadstone is the coarser grade. It goes down under a finer surface course.

For a drive that has thinned out, Driveway Gravel tops what is already there.

Ground and Conditions in Granville

Across the Northwest Iowa Plains the working season runs long once frost is out, but drying winds and low rainfall mean new base and new seeding both need water held on them. That shapes when you want a load dropped.

This is the driest corner of Iowa. Heavy storms arrive as short, hard events rather than soaking rain, so runoff speed is the problem more often than standing water.

Silt loess on the long, even slopes rills and gullies quickly under hard rain.

That is the case for washed stone. Clean rock and 3/4 inch clean stone let roof water and surface water move away instead of pooling against a foundation or a wall.

It is also why stream bank work along this side of the state calls for rip rap at culvert outlets and pond edges, where spring melt cuts fast.

Winters here are open and cold, and the ground freezes deep. Frost heaves gravel surfaces during the spring thaw, so a drive that has thinned out shows it first thing in March.

Any footing depth is set by the building official, and northwest Iowa winters run colder than the state average.
