Bulk Gravel Delivery to Spencer, ID
Idaho Rock Supply handles gravel and aggregate delivery in Spencer, ID, and the calendar matters as much as the material. Winter freezes the ground and stops compaction from late fall into early spring.
The dependable window for base work and flatwork runs from late spring into early autumn. Book road mix and your other loads into that stretch and the ground works with you.
Ground and Conditions in Spencer
Across the Upper Snake River Plain and the eastern farm valleys, young basalt flows sit under thin soil. Water that soaks in has nowhere to go, and the rock below holds it.
A thin base over that ground shows it fast. The surface shifts, pockets open, and a paver or slab edge drops out of line.
The fix is a base course that locks up and a drainage layer that moves water off the site. Road mix gives you the first, and clean rock gives you the second.
Spring runoff off the Caribou and Centennial ranges and snowmelt through the canals work on the same ground. Cut banks and culvert outlets take the worst of it.
Frost depth is set by the local building official, so check with the county before you plan footings.
Materials for Spencer Projects
Bedding under pavers and flatwork is where the wrong pick shows up first. The bedding has to sit even, stay put, and let water pass without washing out from under the slab.
Base and Bedding
3/4 Road Mix is the base course under driveways, parking pads, shop floors, and shed slabs. It is crushed base with the fines left in, which is what lets it lock up under a roller, and Idaho yards call it road mix, 3/4 minus, or crushed base.
On public works plans the same material is written as crushed aggregate by type rather than by class number. That is how it gets specified, not a grade anyone stamps on a ticket.
Stone Screenings handle the fine work: paver bedding, joint filling, and compacted path surfaces where you want the material to knit tight.
For a flatwork base that has to drain, Pit Run goes in as sub base under the road mix. Pit run is unprocessed gravel straight from the pit, used to fill holes and raise grade, never as a finished surface.
Drainage and Surfacing
Drain Rock is clean, angular washed rock for french drains, foundation drains, drywells, and downspout runs. It comes in 3/4 inch, 1 1/2 inch, and 2 inch sizes.
3/8 Chip tops a compacted base on pathways and leveling courses. Chips are angular, so they knit together where Natural Pea Gravel rolls.
Washed Sand beds pavers and slabs, backs up walls, and goes into concrete work.
