#4 Crushed Stone in Iowa

Choosing this stone for the finished driving surface can leave a loose, open texture where a tighter course is wanted. #4 Crushed Stone is better suited to the drainage and support portion of an Iowa driveway, farm lane, or pad. Its crushed, angular rock forms broad voids that let moisture pass and help the course hold its position under heavy traffic.

Loess and glacial till can keep water in the ground, and winter freezing and thawing can work on that moisture. That concern is common on farm lanes and acreage driveways after seasonal rain. Put #4 Crushed Stone below the traveled finish so the stone can carry drainage away from the upper course. It also suits tile outlet drainage and erosion-control work along ditches or slopes where runoff needs a heavy, open aggregate.

Heavy-Duty Base

Use below acreage driveways and farm lanes where traffic needs support.

Erosion Control

Place along banks, swales, and ditches to limit soil washout.

High-Volume Drainage

Wide spaces between pieces let water move through fast.

Gabion Fill

Works as fill material in wire rock baskets and wall systems.

Strong Drainage

The stone's open layout allows substantial runoff to pass through.

Load Bearing

Helps hold its position beneath machinery and vehicle traffic.

Erosion Resistant

Its weight and angular shape help it stay put on grades.

Durable Base

Provides a dependable lower layer for a driveway or pad.
