Materials for Thompson Projects

Fill and sub-base come first here, because raising grade and building up a pad is what most sites in this country need before anything else goes down. Fill dirt is the starting point when you are bringing low ground up to level or backfilling ahead of a base.

Untreated base course goes over that fill as the compacting layer. Size it by top size, 3/4 inch minus or 1 1/2 inch minus, and keep the local name on the ticket.

For a driveway, order untreated base course or road base as the compacted layer, then surface it with driveway gravel. For a patio or paver walk, crusher fines bed the pavers and washed sand levels them.

For a drain, drain rock handles French drains, footing drains and downspout runs. Washed rock is the same clean stone under the name Utah yards use just as often.

Decorative work takes Natural Pea Gravel for walkways and dog runs, and large river rock for dry creek beds and swales where runoff would move a smaller stone. Screened topsoil starts a lawn, and shredded mulch holds moisture in beds through a hot summer.

Ground and Conditions in Thompson

Across the Canyon country and the Castle Valley shale, the ground runs to red sandstone derived sand and thin rocky soil over slickrock. In the shale country it turns to deep clay that swells when it is wet and shrinks and cracks when it dries.

That clay is alkaline, low in organic matter, and gypsum bearing in places. New lots are often stripped to subsoil, so imported screened topsoil is the usual start for a lawn.

Water is the other half of it. Summer monsoon cloudbursts run straight off slickrock and hardpan into the washes, and shale clay sheds almost everything that falls on it.

Water standing on shale clay is what ruins a base. That is why a drain layer and a compacting base matter more here than the surface material on top of them.

The working season is long and the summer is hot. Late-summer monsoon storms are the interruption, and a wash can run hard with no rain falling on your site at all.

Flash flooding moves the washes and arroyos, gullies cut the shale badlands, and wind moves sand off the slickrock benches. Rip rap armors wash banks, culvert outlets and ditch banks against that runoff.

Winter here gives cold nights and mild days, so shallow freeze-thaw repeats rather than one long freeze. Frost depth is set locally and moves a lot with elevation in this part of Utah, so confirm it locally before you build.
