Riprap, Stone and Soil Delivery in Lander, WY

Wyoming Rock Supply handles gravel and aggregate delivery in Lander, WY, from the coarse rock that armors a bank to the crushed base that carries a drive. This ground is coarse granite outwash and cobble washed off the Wind River Range.

That mix of cobble and clay is why crushed base, also called 3/4 minus, matters here. It compacts into a surface that sheds water instead of pumping it back up.

Materials for Lander Projects

Water off the range is the hard part of building in the Wind River Basin. Snowmelt and irrigation water move fast, and they cut.

Slope, swale and bank work starts with rock that is heavy enough to stay where it lands.

Coarse rock for banks and swales

Riprap, also called armor rock or shot rock, lines stream banks, culvert outlets, draws and ditches. It is the material for holding a slope against spring runoff.

Large River Rock works under downspouts and in dry creek beds. It is rounded stone, so it moves water rather than locking into a wall.

#4 Crushed Stone, or 1 1/2 inch rock, suits trench bottoms and heavy drainage where a smaller stone would wash out.

Drainage stone and clean rock

Washed Rock, also called drain rock or 3/4 clean, is washed so the fines are gone. That is the point of it in perimeter drains, foundation drains and downspout runs.

3/4" Crushed Stone goes into drainage beds, pipe bedding and construction entrances. #57 Stone and #67 Stone are specified locally by inch size, and both drain well.

Base, bedding and surface materials

Crushed Base is the standard Wyoming base for driveways, shop pads and parking areas. Pit Run is unprocessed pit gravel for deep fill and for sub-base under a crushed base course, not a finished driving surface.

Scoria, the red burnt-coal clinker also called red rock, covers paths, walkways, drives and pads. Stone Screenings bed pavers and flagstone and pack into a path surface that holds together in wind.

For planting, Top Soil and Garden Soil go over thin, stony or alkaline native ground. Washed Sand beds flatwork and pavers, and Mason Sand serves brick and block work.

Delivery to Lander and the Surrounding Area

Wyoming Rock Supply delivers bulk material across Lander and the rest of Fremont County, including Riverton, Arapahoe, Fort Washakie, Dubois and Shoshoni. You order online and pick a delivery date at checkout.

Quantities are ordered by the ton or by the yard. Each product page has a calculator, so you can size the load before you order.

A dump truck then tips it on site in one pile.

Think about where that pile lands before the truck arrives. It needs room to sit clear of the work, and it needs ground firm enough to hold the weight.

Ground and Conditions in Lander

Work here runs from spring breakup into autumn on the basin floor. Snowmelt off the Wind River Range keeps the ground wet into late spring, so timing a delivery around that matters.

The subgrade is the real constraint. Alkaline clay stays soft under a drive long after the surface has dried, so a base course needs enough depth to bridge it.

Wind across the open basin cuts gullies in badlands and along the bluffs, and high water scours banks. That is why coarse stone belongs on slopes and swales, and why drainage stone needs its fines washed out.

Winters are cold with deep frost on the basin floor, though chinooks off the range thaw the surface out of season. No published frost depth was found for Lander, so footing depth is set by the local building department.

Questions About Stone in Lander

What stone should I use for drainage in Lander?

For a perimeter, curtain or foundation drain, use washed rock, also called drain rock or 3/4 clean. It is washed so the fines are gone, which is what lets water move through it.

For a drainage bed or pipe bedding, 3/4 inch crushed stone works. #57 and #67 stone drain well too and are usually asked for locally by inch size.

What should I have ready when the truck arrives?

Have the drop spot clear and reachable, with room for the truck to tip the load in one pile. The driver tips it where the truck can safely stand and does not spread or place it.

Firm ground helps, since a loaded truck is heavy. If the ground is soft from spring melt, pick a spot that will hold up.
