#4 Crushed Stone in North Dakota

Building a farm approach or shelterbelt lane on North Dakota clay calls for aggregate that does not close up when spring moisture arrives. Flat soils in the Red River Valley can retain water, while gumbo west of the Missouri River creates similar concerns. #4 Crushed Stone leaves substantial open voids between its crushed pieces, allowing drainage where a heavy-use course needs to handle a large volume of water.

Use this material below a tighter road finish, not as the final travel surface. Its angular form helps resist movement under traffic, and it fits erosion-control work near the Missouri River. Where deep frost acts on wet ground, keep this stone in the drainage-support course beneath finer material that can be compacted. That arrangement gives water space to move while the upper course provides a firmer driving finish.

Traffic Base

Use it beneath driveways and other areas with steady vehicle traffic for a firm support layer.

Washout Protection

Place larger rock along banks, ditches, and channels to reduce erosion from runoff.

Water Throughput

Wide spaces between the stones let heavy water flow move through quickly.

Basket Fill

Use it to fill gabions and for retaining structures.

Free Drainage

Open space in the stone allows heavy water flow through.

Equipment Support

Helps keep the layer from moving under equipment and vehicles.

Slope Hold

Weighty, angular pieces are less likely to slide on slopes.

Foundation Layer

Builds a base layer made to last.
