Blacktop that holds up in Cool Valley

I-70 and Florissant Road are the main roads through this small city, and the interchange between them, exit 240, sits inside the city limits. Part of the University of Missouri-St. Louis property also lies within Cool Valley, so campus edges and quiet neighborhood streets end up close together.

The city was incorporated in 1951, and plenty of its driveways are working on their second or third surface by now. We rebuild failed base, pave in hot-mix asphalt and set grades so water reaches the street. Lots near the interchange take heavier traffic, and their base gets sized for it. Crack filling and seal coating come later, once new asphalt has cured for months. Free estimate at (866) 490-7680, and 25% off.

Driveway paving in Cool Valley

A drive from the early 1950s has had seventy-odd winters working underneath it, and the question is whether the base is still sound. Narrow cracks over firm ground can take an overlay. A drive that flexes underfoot, or keeps growing the same pothole, needs the base dug out, re-rocked and compacted, then repaved at typically 2 to 3 inches of compacted hot mix.

Parking lot paving in Cool Valley

Church, school and apartment lots make up much of the commercial paving in a city this size, and Cool Valley Elementary sits on South Florissant Road. School and church lots take buses and delivery trucks in short, heavy bursts. We size the base for those vehicles and settle the drainage before the striping layout is final.

Parking lot paving

Road construction & private roads

Side streets, apartment access drives and parking entrances take a beating near a busy interchange. We grade and crown, compact rock in lifts and pave to the traffic, with deeper base where vehicles enter, brake and turn. Firm edges keep pavement from breaking away where there is no curb to hold it.

General asphalt paving & repair

General asphalt work in Cool Valley covers the jobs that do not fit neatly in a box: alley aprons, walkways, basketball pads, repairs where a utility trench was cut, and overlays that bring a tired surface back. Each one gets the same treatment: a clean edge, a sound base and hot mix rolled tight.

Why the base matters in Cool Valley

North County is rolling upland with the clay-heavy soils common around St. Louis. Clay takes on water, swells, then shrinks as it dries, and pavement over that movement cracks. Freeze-thaw winters widen those cracks into potholes. We fix the drainage and compact the base properly before any asphalt goes down.

A cheap bid usually gets cheap somewhere you cannot see. Ask what depth of stone goes down, how thick the asphalt is after rolling, and who fixes it if water still stands.

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 Cool Valley estimate is sized to the soil, the traffic and the drainage on your property.

Cool Valley paving questions

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

Can a lot be paved in sections so it stays usable?

Yes. We split the lot into phases, close one area at a time and keep an entrance open. For a church or school, the work gets scheduled around services and school hours when weather allows. That plan is set with you at the free estimate.

Why does a pothole keep coming back in the same spot?

Water in the base. A patch fills the hole but leaves the soft material underneath, so traffic works it loose again within a season. The lasting fix is cutting out that section, replacing and compacting the rock, repaving it, and correcting whatever keeps sending water there.

Should I sealcoat my new driveway right away?

No. Fresh asphalt in Cool Valley needs time to cure before it is sealed, typically several months and often up to a year. Sealing too early can trap oils in the pavement. After that, sealing every few years helps it resist water, sun and salt.

Do you have to close the street to pave my drive?

No. Paving a Cool Valley driveway happens on your property; trucks stage at the curb for the day and the street stays open. If an apron tie-in means a short blocked stretch at the street, we tell you which hours that falls in.
