Paving across St. Charles County
St. Charles County sits between the Missouri and the Mississippi, and it keeps growing. New building runs along I-70 and Highway 40 (I-64) and up Highway 61 and Route 79 around Wentzville. About 43 percent of the county lies in floodplain, and elevations run from roughly 397 feet at the confluence to about 902 feet in the south-central part of the county. That spread means a drive out near Augusta and a lot in St. Peters are not the same job.
We pave driveways, parking lots and private roads in hot-mix asphalt over compacted rock. The county soil survey notes that some upland soils here lack strength for traffic without added crushed rock in the road base, and that clayey subsoils carry high shrink-swell potential. So we size the base for the ground in front of us. Call (866) 490-7680 for a free estimate and 25% off.
Ground and drainage
Two things shape paving here: clay and water. Clayey subsoils swell as they take on water and shrink as they dry, working the pavement above them. Low ground floods, and the county is close to half floodplain. Add freeze-thaw winters and a thin pad over soft ground fails fast. We grade for runoff and compact the base in layers before any asphalt goes down.

St. Charles County paving questions
Why does my driveway crack along the same line every year?
Usually the base, not the asphalt. Clay subsoil common here swells with water and shrinks as it dries, and frost lifts anything sitting on a wet base. A crack that returns in the same place is telling you the ground under it moves. We fix the base first.
Can you pave in the river bottoms?
Yes, with the base built for wet ground. Low parts of the county are floodplain, and a pad laid over soft, saturated subgrade will rut. We check drainage, add crushed rock where the subgrade is weak, and slope the finished surface so water runs off instead of standing.
