Blacktop that holds up in St. Mary

Founded as St. Mary's Landing by families of French descent, this Mississippi bottomland town runs along Highway 61 in Ste. Genevieve County. The ground sits low and flat, and that fact drives nearly every paving decision here. We pave driveways and farm-yard lots, along with church and shop lots in town.

An old channel of the Mississippi separates the town from Kaskaskia Island to the east, and the bottoms drain slowly. That drives everything about how we build. An EF3 tornado came through in October 2021, and rebuilt properties often need their drives and approaches redone to match new grading. I-55 exit 141 brings traffic in on Route Z.

Driveway paving in St. Mary

Bottomland drives sit on ground that holds water, so we build the base higher and heavier than the same drive would need on a hill. That means removing soft soil, compacting rock in layers, and shaping the surface so water runs off the sides. Hot-mix asphalt typically goes down 2 to 3 inches compacted for cars and pickups, thicker where a farm truck uses it.

Parking lot paving in St. Mary

Church lots, shop pads and farm yards make up most of the commercial paving here. We size the base for grain trucks and equipment rather than cars, plan the turning room, and place asphalt in lifts. On a large yard, recycled asphalt over a compacted base is often the better value.

Parking lot paving

Road construction & private roads

We build and repave farm lanes, field access roads and private drives running out to the bottoms. Each gets grading, a compacted rock base and a crown to shed water. Where a lane meets Highway 61 or Highway U, the entrance gets extra base, since turning trucks break edges before anything else.

General asphalt paving & repair

Around St. Mary we see plenty of pavement that has been patched over and over. Sometimes one more patch is the right call. Sometimes a mill-and-overlay or a rebuild saves money over the next ten years. We will lay out both options so you can choose.

What's under a St. Mary driveway

Flat river bottomland drains slowly, and asphalt built on wet ground moves. We raise and crown the surface, take out soft soil, and compact rock in layers so the base stays solid. Freeze-thaw winters then have nothing trapped underneath to work against, which is most of what keeps pavement flat.

Before you sign anything, get the base depth and the compacted asphalt thickness on paper. Two bids that look far apart are often just two different pavements.

Compacted asphaltTypically 2 to 3 in. for a car drive
Stone baseTypically 4 to 8 in., compacted
Drive on itUsually 2 to 3 days, longer in heat
First sealcoatTypically 6 to 12 months after paving

Typical ranges. Your St. Mary estimate is sized to the soil, the traffic and the drainage on your property.

St. Mary paving questions

Straight answers for St. Mary homeowners and property managers. Anything else, call (866) 490-7680.

Does bottomland ground change how you build?

Yes. Wet, slow-draining soil needs more preparation than firm hill ground. We remove soft material, bring the grade up, and put more rock under the asphalt. Getting water off and away from the pavement matters more here than the thickness of the surface.

Do you work in Ste. Genevieve and Perryville?

Yes. St. Mary sits between them on Highway 61, and we work across Ste. Genevieve County and the surrounding area, plus greater St. Louis. Estimates are free, and you get 25% off. Call (866) 490-7680.

What kind of base should go under a St. Mary driveway?

Typically a compacted crushed-stone base several inches deep on firm soil, with soft spots dug out first, and that holds for any St. Mary driveway. On clay soils that hold water, a thicker base and good slope matter even more. The estimate states the base depth so there are no surprises.

Do you do smaller repairs, or only full driveways?

Both. Patching a failed section, filling cracks before winter and rebuilding an apron are regular work in St. Mary. We will tell you honestly when patching is throwing good money after bad.
