Rock products

Three-quarter-inch crushed rock with fines, graded to Idaho Transportation Department Type B. The workhorse road base — it compacts tight and holds up under traffic.

Three-quarter-inch minus crushed rock that isn't held to an agency gradation. Same material, same compaction, lower cost — the value pick where no spec is called for.

Five-eighths-inch minus crushed surfacing graded to Washington State DOT requirements. A finer base that finishes smoother than 3/4" minus.

Inch-and-a-quarter minus crushed base graded to Washington State DOT requirements. A deeper, coarser base course for heavier loading.

Inch-and-a-quarter minus with fines, not held to an agency spec. Economical deep base where the gradation doesn't have to be certified.

Three-inch minus crushed rock. Coarse and heavy with fines to bind it — built for building up soft ground before a finer base goes on.

Granular subbase aggregate — the lower structural layer placed beneath a base course.

Surfacing aggregate graded to Idaho Transportation Department Rock Cap Class 1 — the finish layer over a completed base.

Inch-and-a-quarter clean angular rock with the fines screened out. Locks together under load and drains freely.

Two-inch clean angular ballast. Coarser voids, faster drainage, more load spread than 1-1/4".

Three-inch clean angular rock. Used where the ground is wet or soft and water has to move through the layer.

Four-inch clean angular rock — the largest of our ballast sizes, for the softest ground and the heaviest traffic.

Three-eighths-inch uniform crushed chip, washed clean of fines. The standard chip seal size.

Half-inch uniform crushed chip. A coarser seal coat aggregate with more texture underfoot and underwheel.

Five-eighths-inch clean chip sized for bedding and haunching pipe. Beds evenly around the barrel and drains rather than holding water against it.

Concrete aggregate chip — washed crushed rock graded for batching into concrete mixes.

Three-eighths-inch aggregate graded for Type 3 slurry seal — the coarsest slurry grade, for roads carrying real traffic.

Large angular stone placed to stop moving water taking ground with it. Sized and keyed together so the bank stays where you put it.

Four- to eight-inch angular quarry rock. The go-to for construction entrances — big enough to knock mud off tyres, angular enough to stay put.

Blasted rock straight off the face, uncrushed and unsorted. Rough, cheap and effective when you need mass and volume.

Washed rock with the fines taken out, so water runs through instead of sitting in it.

Oversize and off-gradation material screened out of production. Inconsistent by nature, and priced accordingly — the cheapest way to move volume.

Material as it comes out of the pit — unscreened and uncrushed, a natural mix of rock, gravel and fines.

Boulders selected for how they look. Set as features, borders and low walls.

Boulders with flat broken faces, so they stack and stay stacked. The ones to use when the wall has to hold.

The biggest we pull — machine-set only. Statement rock for entries, parks and large-scale grading.

Sand washed to take the silt and clay out. Clean, consistent and ready for mixing or bedding.

Natural sand with rock up to two inches left in it. Unprocessed, well-graded and economical for bulk work.

Screened topsoil, our better grade — for finish work where things actually have to grow.

Native topsoil as dug. Good general-purpose soil for filling and rough grading.

Two-inch rounded river rock, smooth and naturally coloured. Decorative, and it drains.

Disposal of clean broken concrete and asphalt at our sites. Bring it in and we'll take it — it gets crushed and put back to work.

Disposal of clean dirt and excavation spoils at our sites.
