Start with 3/4 minus. It is the standard base under a patio, a driveway or a shop floor in this part of Oregon, and it compacts because it keeps its fines.

Ground and Conditions in The Dalles

Across the Columbia River Gorge and Plateau, the ground is basalt under wind-laid loess. Deep silt covers the wheat ground, and soil turns shallow where the basalt comes near the surface.

Wet loess turns greasy and will not hold a load. Dry loess sheds water fast, and runoff crosses frozen ground in winter.

A thin base shows its failure fast under a patio. The pavers rock, joints open, and the edges settle out of line.

The fix is a compacted base that carries the load and a bedding layer that stays flat. Build the base first and the finish holds.

Precipitation here runs 8 to 15 inches a year, so volume is rarely the problem. Silt, wind and sudden summer runoff in dry draws are.

Frost goes deeper here than west of the Cascades, and the working season runs from hard frost to summer dust. Water for compaction often has to be hauled on the plateau, so plan the timing.

Materials for The Dalles Projects

Bedding decides how a patio looks in five years. The layer under the pavers has to sit flat, lock up, and stay put while you work across it.

1/4 Minus, also called quarter minus, is the bedding product for pavers and flagstone. Crushed fines grade out fine and tight under a screed board.

3/4 Minus is the base course under that bedding. Crushed rock graded 3/4 inch down to fines, it compacts and locks up under driveways, parking pads, shop floors and shed bases.

Washed Sand beds pipe, levels under slabs and flatwork, and mixes into concrete. It is washed so it drains instead of holding water.

Drain Rock, also called 1 1/2 clean, is washed and open. Water moves through it, so it suits French drains, footing drains and downspout runs.

3/8" Crushed Stone covers pipe bedding, tight drainage work and a fine topping over a compacted base.

Questions About Gravel and Sand in The Dalles

What gravel is best for a driveway in The Dalles?

Use 3/4 minus for the base. It is crushed rock graded 3/4 inch down to fines, so it compacts and locks up instead of rolling under tires.

Local silt moves when it is wet, and a minus rock that holds together handles that better than a clean stone. Top an existing drive with the same material.
