Water is the first thing to plan for in a town named after a canoe portage. This one sits in the Mississippi River bottoms, and flooding here is not theoretical: the village library branch closed after the 2019 high water. Paving on this ground means the base and the drainage do the heavy lifting.
We pave driveways and parking lots for homes, churches and the businesses that serve river traffic, plus the access roads and yards behind them. Highway J is the road in and out. Bottomland subgrade can be soft and slow to dry, so we correct it with compacted rock instead of paving over it and hoping. Free estimates, and you get 25% off.
A drive on floodplain ground needs a base that stays firm while the soil under it is saturated. We dig out soft material, bring in clean rock and compact it in layers, then set the surface so water runs off quickly instead of standing. Home drives typically finish at 2 to 3 inches of hot mix. Raising the finished grade slightly is often worth talking through here.
Driveway pavingChurch, shop and boat-access lots down here take trailers and loaded trucks on ground that does not drain quickly. We build the base for that weight, pitch the surface so runoff leaves at a planned point, and support the edges where trailers swing wide and drop a wheel off the pavement.
Parking lot pavingLevee access roads, farm lanes and the drives serving river bottom property need crown, ditches and a compacted rock base more than they need thick asphalt. We grade and drain first, then pave to the width and thickness the traffic calls for. Recycled asphalt millings make a practical surface for long bottomland lanes.
Road constructionAround Portage Des Sioux 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.
Asphalt paving
About 43 percent of St. Charles County lies in floodplain, and the county soil survey notes some soils lack strength for traffic without added crushed rock in the road base, with clayey subsoils that shrink and swell. On bottom ground near the confluence that is the whole story. Rock depth and drainage decide how long pavement lasts.
The part of the job you can see is the last two inches. Ask what is underneath, how it will be compacted, and which way the finished surface drains.

It can, with the right build. Asphalt over a compacted rock base handles saturation better than loose gravel, which simply washes away. What matters is getting the base above the soft material and giving water a fast way off the surface. We look at the site first.
We find out why. Usually it is a shallow base over wet subgrade, a ditch that has filled in, or a culvert that no longer carries water. Fixing the drainage comes first, then we build the base deep enough to stay firm through the wet season.
Sometimes. If the base under your Portage Des Sioux pavement is still solid and the surface only has shallow cracking, an overlay can work well. If the pavement is sinking, rutting or breaking into alligator cracks, the base has failed and it needs to be rebuilt first. The free estimate is where we sort that out.
Yes, and we phase it so the lot stays usable. Most small Portage Des Sioux lots are done in sections, with the entrance kept open where possible, so a business or a Sunday service is not shut out while the asphalt cures.
We pave all around Portage Des Sioux, across St. Charles County and the rest of greater St. Louis on both sides of the river.
