Centennial driveways are hitting the age where the base gives out
Most of Centennial went up between the 1970s and the 1990s, which means the original builder concrete under your tires is now 30 to 50 years old. That's not old for a slab. It's old for the fill beneath one. Builders back then compacted the base about as well as the schedule allowed, and five decades of Colorado clay swelling and shrinking has finished the settling the compactor never did. Your driveway didn't wear out. The ground under it quit.
We've been lifting Front Range driveways since 1988, and the pattern here is a familiar one. We drill 1-1/2" holes through the settled sections, pump a slurry of water and sandy loam soil into the washed-out base, and bring the slab up while a level rides the surface. Trevor will tell you at the estimate how long to keep foot and car traffic off the slab.
What 5,830 feet does to a slab every winter
Centennial sits higher than central Denver, and the difference shows up at night. Colder overnight lows put the ground under your driveway through more freeze-thaw swings per winter than a slab a few hundred feet lower would see. Each cycle, water in the base freezes, expands, and shoves soil around. Each thaw, some of that soil migrates toward the nearest low spot. Since nearly the whole city drains toward Cherry Creek or Piney Creek, the low spot usually wins.
Lots on the drainage sides take the worst of it. Water moving toward the creeks pulls fines out from under slab edges a little at a time, and a driveway on one of those lots can lose base support for years before the surface admits it. If the panel by your garage rings hollow when you knock on it, that's the base telling on itself.
The three failures Centennial driveways show most
- The tipped apron. Street water undercuts the driveway at the gutter line. The apron drops, the car scrapes, and every storm digs a little deeper.
- The gap at the garage door. The panel in front of the garage settles and daylight opens under the weatherstrip. Mice find that gap before you do.
- The downspout panel. One slab drops while its neighbors stay put, and there's a roof drain dumping at its edge. We lift the slab and ask you to extend the downspout so the fix sticks.
Hail season adds its own entry. Centennial's east side catches real hail exposure, and the storms that carry hail also drop an inch of water in twenty minutes. Clay can't drink that fast, so the runoff races along slab edges and carves base material out on its way downhill. A driveway that made it through winter level can come out of one July storm with a soft corner.
What it costs, and when we'd tell you to replace instead
Every Centennial driveway gets its own number, quoted free and in person; for a national yardstick, HomeAdvisor puts a typical residential mudjacking job between $300 and $2,500, with an average around $950. Tearing out and repouring the same driveway costs double or triple what a lift does. That gap is why lifting deserves a phone call even if you're not sure your slab qualifies.
Some don't qualify, and we'll say so standing in your driveway. A slab in one to three sound pieces lifts and holds for years. A slab broken into many small pieces rises unevenly and the joints reopen, so we'll point you toward replacement rather than sell a repair with a short life. Same answer if the surface is scaling off in sheets, because a lift restores grade, not finish. Trevor gives you that verdict for free, in writing, with no follow-up pressure.
One truck, one continuous pass
Our pump truck carries 10 yards of material, so we never leave a slab half-raised while somebody drives off to refill. The truck parks on the street, the portable pump comes right to the slab, and your lawn never sees a tire tread. Drilling, pumping, patching, and cleanup happen in one visit for almost every driveway in the city. The crew shows up with the biggest truck in the local trade, and it's the same company you'll reach if anything ever needs a touch-up.
Call (303) 526-2222 or request your free estimate and Trevor will come measure the drop in person. If you'd like the full method explained first, the driveway leveling page covers it from drill to patch.
