Driveways and Patios So Good, Water Doesn’t Stand a Chance.

Expert Concrete Solutions That Last

At 20,000 Leaks Under The Basement, we don’t just pour concrete, we build bulletproof surfaces that look stunning and actively protect your home from water intrusion for years to come. We are one of the few local contractors, the best in our humble opinion, that combines master level concrete craftsmanship with proven waterproofing and drainage systems. We deliver gorgeous, long-lasting driveways, stamped patios, walkways, retaining walls, and foundations that last for many years. If you’re tired of patching problems and ready for concrete done right the first time, you’ve found the right crew.

Why Choose 20,000 Leaks Under The Basement as Your Concrete Contractor

Most homeowners don’t realize that 90% of cracked driveways, sinking patios, and wet basements start with one thing: poor concrete work that ignores water. At 20,000 Leaks Under The Basement, we refuse to let that happen. We’re not just another concrete company that happens to do waterproofing, we’re the only local contractor that started in basement waterproofing and grew into a full-scale concrete powerhouse. That means every slab, driveway, patio, and retaining wall we pour is engineered from day one to keep water moving away from your foundation, not toward it.

Concrete Driveway Side of House

One-stop shop—no finger-pointing, ever.

Waterproofing, drainage, excavation, and concrete all handled by the same licensed, insured crew you already trust. One contract, one warranty, one captain in charge.

Zero callbacks. Period.

We’re proud (and a little obsessed) with our perfect callback record on concrete. Proper base prep, professional grade mixes, fiber or rebar reinforcement, and a full 7-day curing process mean your new concrete stays flat, crack-free, and beautiful for decades, or we come back and make it right at our expense.

Any look you want, without the custom price tag.

Want the high-end look of stamped cobblestone, seamless exposed aggregate, rich earth-tone acid staining, or modern polished finishes? We stock over 40 stamp patterns and every major integral color and stain line, yet price like a production contractor because we do the volume.

Full tear-out to final seal—nothing left to chance.

Old concrete removed, hauled away, and legally disposed of. Subgrade laser-graded for perfect drainage. New base material compacted in lifts. Forms set dead-level. Concrete poured, vibrated, hand-finished, control joints cut the same day, and sealed with commercial-grade penetrating sealer. You get the complete job—no shortcuts, no “that’s extra.

Built-in water management intelligence.

Every pour includes proper slope-to-drain, perimeter drainage tie-ins when needed, and expansion materials that actually work. The result? Your new driveway or patio looks gorgeous and actively protects your basement from water intrusion.

Benefits of Choosing 20,000 Leaks Under The Basement for Your Concrete Project

One Crew, One Captain – Zero Subcontractor Drama

Most companies bid low, then farm your job out to the cheapest crew they can find. Not us. The same licensed, background-checked, full-time 20,000 Leaks crew that shows up to waterproof your basement is the exact same crew that tears out your driveway, forms it, pours it, stamps it, and seals it. One phone number. One warranty. One captain accountable for the entire outcome.

Finance Options

We provide flexible, no-hassle financing options through a trusted third-party lender, making it easier than ever to get your basement dry and protected, often without upfront payment worries.

Built-in Drainage Intelligence on Every Pour

Because we live and breathe basement waterproofing, every single concrete project is designed like a water-management system in disguise. Laser-graded slopes, strategic high points, tie-ins to existing or new drainage, and expansion joints placed where water actually wants to go. The result? Your new driveway or patio looks gorgeous and actively keeps water away from your foundation for decades—no more pooling, no more basement leaks caused by bad concrete.

Instant Boost in Home Value

Realtors and appraisers agree: fresh, high-quality concrete is one of the highest-ROI exterior upgrades you can make. A new driveway alone often adds $12,000–$25,000 to appraised value in our market. Add a stamped or stained patio and you’re routinely pushing $30,000+ in instant equity and curb appeal that makes your house the best-looking one on the block the day we pull away.

Custom Designer Looks at Everyday Prices

Want the upscale look of European cobblestone, flagstone, wood plank, seamless exposed river rock, or deep charcoal acid-stained modern polish? We keep over 40 professional stamp patterns, every major integral color, and premium release/stain lines in stock year-round. Because we pour so much concrete, we buy direct and pass the savings to you—boutique finishes at production-contractor pricing.

Lightning-Fast 3–7 Day Project Completion

No waiting weeks for different subs to show up. Our in-house excavation, demolition, forming, finishing, and stamping teams work like clockwork. Average driveway replacement: 3–5 days from tear-out to driving on it. Stamped patio additions: 4–7 days. We schedule tight, show up on time, and get you back to normal life faster than anyone else in town.

Bottom line: When you choose 20,000 Leaks Under The Basement, you’re not just buying concrete—you’re investing in peace of mind, higher property value, and a stunning outdoor space. That’s the Captain’s way.

Common Concrete Problems We Solve

Every day we pull up to homes where beautiful houses are being quietly destroyed by bad concrete and ignored water. If any of these sound familiar, you’re in the right place.

Cracked, Sinking, or Heaving Driveways

The nightmare triad: spider-web cracks, sunken panels by the garage, or sections that jack up every winter. Usually caused by poor base prep, thin concrete, no reinforcement, and freeze-thaw cycles. We rip it out to the dirt, install a proper compacted gravel base, pour minimum professional grade concrete with fiber or rebar, and you drive on a flat, flawless driveway again—forever.

Outdated, Stained, or Crumbling Patios & Walkways

That 1980s broom-finished slab that’s now gray, oil-stained, cracked, and an eyesore? Or the stamped patio someone tried 20 years ago that’s peeling and faded? We demolish the old mess and give you today’s hottest looks—cobblestone stamp, exposed aggregate, modern acid-stained polish, or seamless colored concrete that makes your backyard the envy of the neighborhood.

Poor Drainage Pushing Water Against Your Foundation

This is the silent basement killer. Flat or negatively sloped concrete funnels thousands of gallons of rainwater and snowmelt straight to your foundation walls every year. We redesign the entire area with positive pitch, laser-graded slopes, and (when needed) tie the new concrete into perimeter drains or stairwell systems so water leaves your property instead of trying to get into your basement.

Failing, Leaning, or Bulging Retaining Walls

Old railroad-tie or crumbling block walls that are bowing, tilting, or collapsing under soil pressure. We remove the failing structure, install proper footing with rebar dowels, build reinforced poured concrete or large-block systems with drainage stone and weep pipes behind them. The new wall looks clean, holds back the hill for decades, and actually improves yard drainage.

Wet, Cracked, or Heaving Basement Floors & Foundation Slabs

Water seeping up through cracks, efflorescence dust, or entire sections of floor that lift and buckle from hydrostatic pressure. We cut out the damaged sections (or the entire floor if needed), install interior drainage and new vapor barrier, then pour a new structural slab with fiber reinforcement that ties directly into our waterproofing system. You end up with a bone-dry, flat basement floor ready for finishing. We specialize in foundation wall and crack repair.

If you’re staring at any of these headaches right now, relax. We’ve solved every single one—multiple times—on homes just like yours. One call to the Captain and that problem becomes permanent history.

Commonly Asked Questions for Concrete Service

After 20+ years and thousands of pours, these are the questions homeowners ask us every single week. Here are the real answers—no fluff, no sales pitch, just the truth from the guy who signs every job.

How long does a new concrete driveway, patio, or walkway actually last around here?

With our spec, professional grade air-entrained concrete, fiber mesh + rebar where needed, 4–6″ compacted gravel base, laser-graded drainage, and a full 7-day moist-cure—you’re looking at 25–40+ years of real-world service life, even with salt, snow plows, and Midwest freeze-thaw cycles. Most discount contractors quote 15–20 years because that’s what their shortcuts deliver. We’re still driving on driveways we poured in 2003 with zero cracks.

Do you remove and haul away the old concrete, or is that an “extra” I’ll see on the final bill?

It’s included—100% of the time. We saw-cut, jackhammer, load, haul, and legally dispose or recycle every pound of old concrete. No hidden disposal fees, no “dumpster surcharge,” no surprises. The price you sign is the price you pay.

Can you match my existing concrete color, stamp pattern, or even my neighbor’s patio I love?

Almost always, yes—and it blends so well most people can’t tell where the old ends and the new begins. We carry many professional stamp patterns. Bring us a photo or a chip and we wil get to work.

What happens if it rains on the day of my scheduled pour?

We watch three professional radar sources 24/7. If there’s even a 30% chance of rain during placing or right after the pour, we call you the night before and reschedule—no charge, no penalty, no ruined concrete. Your job only gets poured in perfect conditions, period.

Do you offer financing or payment plans for concrete projects?

Not directly. We provide flexible, no-hassle financing options through a trusted third-party lender, making it easier than ever to get your basement dry and protected, often without upfront payment worries.

How thick and strong do you pour residential driveways?

Standard is a minimum of 5″ professional grade concrete with fiber mesh or #4 rebar on 24″ centers. Heavy-load zones (near the garage, RV parking, dumpster pads) get bumped to 6–8″ thick with extra rebar. That’s commercial-grade strength on a residential job.

Will my new concrete crack? 

All concrete gets saw-cut control joints every 10–12 feet so it cracks exactly where we want it to—if it ever wants to. Random shrinkage cracking is extremely rare with our mix, reinforcement, and 7-day curing process.

Do you also repair or replace cracked, wet basement floors and slabs?

Yes—it’s one of our specialties. We cut out the damaged sections (or the whole floor), install interior drainage and vapor barrier when needed, then pour a new structural slab with fiber reinforcement that ties directly into your waterproofing system. You get a bone-dry, perfectly flat, quality floor.

How soon can you start, and how long does the average job take?

Most driveway replacements and patio additions are scheduled 2–4 weeks out (faster in the off-season). Once we start:

  • Full driveway replacement: 3–5 days from tear-out to drive-on
  • Stamped patio addition: 4–7 days
  • Walkways & sidewalks: 2–4 days
  • We move fast because every piece of equipment and every crew member works for us—no waiting on subcontractors.

Do you pull permits and handle inspections?

Always. We secure every required permit and schedule every inspection. You never have to talk to the city—that’s another reason homeowners love having one captain running the entire ship.
