Large River Rock, Stone and Soil Delivery in Portland, ND

North Dakota Rock Supply brings gravel and aggregate delivery in Portland, ND, and the surrounding part of Traill County. Class 5 is the base gravel this market builds on, and it goes under drives, parking pads and shop floors.

This is flat Red River Valley lake plain ground, deep silt and clay with little stone in it. That shapes what you order and where it goes.

Materials for Portland Projects

Slope, swale and bank protection starts with coarse stone. The Red River Valley lake plain has almost no fall, so water sits until it has somewhere to go.

Coarse rock gives it that path.

Riprap is the heavy end of the range. It is graded Grade I, II and III here, and it armors coulee and river banks, culvert outlets and shoreline against spring runoff and wave action.

Large River Rock works the same way at a smaller scale. Use it for dry creek beds, shelterbelt edging and heavier decorative or erosion work.

Washed Rock is clean stone for drain tile beds, sump discharge, downspout runs and foundation drains. Because it carries no fines, water moves through it instead of pooling.

Class 5 is the standard North Dakota base gravel. It builds driveways, parking pads and shed bases.

Class 13 is surfacing gravel. It binds and blades well on an approach, lane or gravel drive where you want a wearing surface rather than a full base course.

Stone Screenings are the fine end. They bed pavers and flagstone, fill joints and pack into a walking surface.

Delivery to Portland and the Surrounding Area

You order online and pick a delivery date at checkout. Quantities are ordered by the ton or by the yard, and each product page has a calculator to help you size the load.

A dump truck tips the material in one pile at your site. Have the spot clear and reachable before the truck arrives.

Coverage runs across Portland and out to Mayville, Hillsboro, Hatton, Buxton and Caledonia in Traill County.

Ground and Conditions in Portland

Base, driveway and paver work runs from the end of the spring thaw into late fall. Frozen ground stops compaction through the winter, and spring load restrictions slow hauling while the frost comes out.

Across the Red River Valley lake plain, the clay sheds water slowly. Snowmelt and summer rain sit on yards, drives and field approaches instead of running off.

That standing water is why a drainage layer matters before a gravel course goes down. Washed rock and the coarser crushed sizes give water a place to move.

Winters here are long and the ground frost is deep, then the spring thaw heaves and softens gravel drives, approaches and township roads. Plan the work around that window rather than against it.

Spring flooding along the Red and its tributaries scours banks on the meandering channels. Sheet wash and rutting show up across bare clay ground.
