Order Staymat and Crushed Stone in Chittenden County, VT

For gravel, stone and aggregate delivery in Chittenden County, VT, Vermont Rock Supply sells bulk material by the ton and tips it at your site. Staymat is the Vermont yard word for a dense graded crushed base, and it is the starting point for most drives, parking pads and shed bases here.

Around Burlington and the clay plain, that base sits over ground that holds water. Up in Underhill and Huntington, it sits over stony till on a grade.

Both need the right stone underneath.

Materials Delivered in Chittenden County

Staymat is crushed stone graded from about 3/4 inch or 1 inch down to dust, so it locks up tight under a roller. Vermont describes base material through the VTrans Standard Specifications for Construction, Section 301, Subbase, with the aggregate drawn from Section 704.

Crushed gravel for subbase is the spec course under 704.05, and dense graded crushed stone for subbase is 704.06.

Bank run gravel is gravel taken from a pit or bank and screened rather than crushed. Use it as subbase and bulk fill, since it is not a crushed product.

Finer sizes cover bedding and finish work. Pea stone suits walkways, dog runs and dry wells, and river rock handles decorative beds and dry creek beds that carry runoff.

Mason sand and washed sand cover mortar, paver joints and bedding under slabs. Screened loam, garden soil and shredded mulch finish the ground after the stone work.

Ground Conditions Across Chittenden County

This county spans more than one ground region. In the Champlain Valley, Burlington, South Burlington, Colchester and Essex Junction sit on heavy marine clay, silt and fine sand left when the Champlain Sea flooded the lowland.

Clay drains slowly and stays wet, so water sits on the surface through snowmelt and after summer storms.

That makes the working season here the earliest in Vermont, since the valley dries first. The clay still stays soft for weeks through mud season and will rut under a loaded truck, so time a delivery for ground that will hold the truck.

In the Green Mountains, Underhill and Huntington sit on thin, stony glacial till over schist and gneiss, with boulders and ledge close to the surface. The season up there is short, with mud season arriving later and lasting longer and the ground freezing again sooner.

Rain and snowmelt run off those steep, shallow soils fast, so brooks rise quickly and a drive on a grade sheds water down its own surface.

Erosion shows up as steep-gradient streams scouring banks, ditches and culvert outlets in heavy rain, and this is the pattern that did the worst damage in the mountain towns in the August 2011 flooding.

On the clay plain, expect sheet wash and gullying on bare ground, bank scour where streams cut in, and wave action along the Lake Champlain shoreline at high water. Stone fill lines steep ditches and armours culvert inlets and outlets against that.

Winters run mildest in Vermont in the valley, but the ground still freezes hard and thaws repeatedly, and clay that holds water heaves a gravel drive more than a sandy soil does. Frost depth is set by the town.

Confirm footing depth with the town office.

Because this county spans two ground regions, where you are matters more than the county line. A Burlington delivery and an Underhill delivery arrive on different ground, and the base you want on top of it differs too.

Choosing the Right Material

Franklin County shares the Champlain Valley clay plain with the valley half of Chittenden County, so the ground is much the same there. The same holds for the till and outwash on the Green Mountain side.

If you are building on clay, weight your choice toward drainage and a screened bank run subbase before the crushed top course.

Washington County spans more than one ground region, the Vermont Piedmont and the Green Mountains, so its ground overlaps with the mountain side of Chittenden County and differs from the clay plain. Lamoille County sits on Green Mountains ground, thin stony till over schist and gneiss with boulders and ledge near the surface.

Lamoille County shares that ground with Underhill and Huntington, so the base reasoning is the same there. On clay, plan for water that will not drain away.

On till and slope, plan for water that arrives fast.
