Materials for St. Mary Projects

The bluffs and creek banks around St. Mary take a beating every spring, so coarse stone earns its keep here. Rip rap is the first line of defense. You line a swale, a culvert outlet or a washed bank with it and let the storm runoff fight the rock instead of your dirt.

Move down a size and you get the stone that holds ground in place. Here is how the sizes sort out, coarsest to finest.

It is the material that goes under everything else, and it compacts hard once it is watered and rolled. Fill low spots with Fill Dirt first, then build your base rock course on top.

For water that needs to move, Drain Rock is the practical pick. It goes into French drains, foundation drains, downspout runs and the drainage behind a retaining wall. Keep it washed and free of fines so water passes through instead of pooling.

On the fine end, Large River Rock handles dry creek beds and heavier decorative work, while screenings bed pavers and flagstone. Bare loess slopes wash out fast, so stone the steep ground before you plant anything on it.

Delivery to St. Mary and the Surrounding Area

Order online and pick a delivery date at checkout. You choose the quantity by the ton or by the yard, and a dump truck brings it to your site. Missouri Rock Supply covers St. Mary and the rest of Ste. Genevieve County, including Ste. Genevieve and Bloomsdale.

Coverage is the whole area, so the question is usually where the truck can put the pile. A wide, firm spot near the work saves you a lot of wheelbarrow time. If the ground is soft, pick a spot that will still hold weight after a wet week.

Ground and Conditions in St. Mary

Timing matters more than most people expect. Midwinter freezes and heavy spring rain are the usual hold-ups, and low ground near the rivers can stay wet or under water well after a flood crest. Plan a delivery around that window and the job goes smoothly.

The ground itself is silty loess on the ridgetops, sitting over cherty clay and limestone, dolomite, sandstone or shale. Sinkholes form where limestone or dolomite lies close to the surface, so watch for them before you build a pad or run a swale.

Storm runoff drops quickly off the steep bluffs into narrow valleys, and some of it drains underground. The rest gullies bare slopes and road cuts. That is why rip rap on a bank and clean stone in a drain do more for a St. Mary site than any amount of fill.

Freeze-thaw cycles run through the winter here, with January nights below freezing and most days thawing. Frost depth is set by the local building code and runs shallower toward Cape Girardeau than around St. Louis. Base rock and drainage stone still carry the load either way.
