Groundwork Concrete & Flatwork · Grandview, MO

Bid sheet Groundwork Concrete & Flatwork Prepared for: your driveway Curt Voss, since 2004

Measure your driveway and call me. You'll have your whole number before we hang up.

Length times width is most of a flatwork bid, and I've written about four thousand of them. Driveways, patios, sidewalks, garage slabs, in Missouri and in Kansas, same crew and same number either way. The price I give you on the phone is the price on the invoice.

Call Curt, (816) 555-0217 See what you're buying

How to measure your driveway, drawn Plan-view sketch of a two-car driveway between the garage and the street, with dimension arrows marking 20 feet across and 32 feet long, the sawed joint grid drawn in, and a tag reading 640 square feet, call with those two numbers. YOUR GARAGE THE STREET 20 FT 32 FT 640 SF
Those two numbers are the whole phone call.

$9.25
per square foot

Driveway, torn out and repoured. That figure covers the demo, the haul-off, the gravel, the concrete, the finish, the saw cuts and the seal. There is no second page of extras.

Line items

The numbers I'll stand behind

These hold for normal access and normal ground. Rock, roots, a steep grade or a wheelbarrow-only backyard moves the number, and I tell you by how much before you sign anything.

$9.25 / SQ FT

Driveway, tear-out and repour

We break the old slab, haul it, cut and compact the ground, and pour four inches of 4,000 PSI concrete over four inches of packed gravel. The joint pattern gets sawed to follow your lot, because your lot is not a rectangle from a catalog.

Most single-car drives come out on a Monday and you park on the new one the Wednesday after next.

$7.75 / SQ FT

Patio, new pour

Broom, swirl or a light rock-salt finish, and I'll tell you straight that plain broom ages the best. Every patio gets pitched a quarter inch per foot away from the house, so the water goes to the yard and not the basement.

Stamped adds $4.50 a foot. We form curves with hardboard when you want one.

$8.50 / SQ FT

Sidewalk, stoop or apron

City walks get poured to the city's spec, and where a right-of-way permit is required, I file it and I meet the inspector. The permit fee shows on your invoice at cost with the receipt stapled to it.

The KCMO, Overland Park and Lee's Summit permit counters know my handwriting by now.

$6.90 / SQ FT

Garage or shed slab

Floating slabs and turned-down monolithic pours, steel trowel finish, anchor bolts set wet to your plan. Bring me the building manufacturer's foundation sheet and we pour to it, not around it.

Floor pitched to the door or to a drain. You pick, I'll tell you which one I'd do.

$0.48 / SQ FT

Reseal and joint caulk

On a slab we poured or one we didn't. Pressure wash, seal, and new caulk where the old caulk has let go. It's cheap insurance against a Kansas City winter, and fall is the right time, before the first salt hits it.

$180 minimum gets the truck to your house.

Half is due when the old slab comes out, and the other half when you have walked the new one. No deposit before work starts. If we open the ground and find a surprise, you get a phone call before you get a bill.

Attachment A

The drawing stapled to every bid I write

This same cross-section has gone out with every bid since 2004. It's how I show you what your money is buying, because most of it ends up underground where you'll never see it.

The mix is 4,000 PSI with 6% entrained air, which is what survives twenty winters of freeze, thaw and street salt. A cheaper no-air mix is how you get a driveway that flakes apart in year three, and I don't stock one.

People ask why I talk about gravel so much. Your slab is only as strong as what it sits on, and what it sits on is the part nobody photographs. The gravel is the job.

Slab cross-section, labeled in Curt's words Cut-away drawing of the standard slab. A control joint at the surface labeled: sawed the same afternoon we pour. A four-inch concrete slab labeled: four inches of 4,000 PSI, 6% air. Rebar at mid-depth labeled: number four rebar, 24 inches apart, nobody pays extra for it. A gravel base labeled: four inches of AB3, packed twice. The gravel is the job. Compacted ground below labeled: your dirt, compacted before anything goes on it. SAWED THE SAME AFTERNOON WE POUR #4 REBAR, 24" APART. NOBODY PAYS EXTRA FOR IT. 4" OF 4,000 PSI, 6% AIR 4" OF AB3, PACKED TWICE. THE GRAVEL IS THE JOB. YOUR DIRT, COMPACTED FIRST

Schedule

How your driveway week goes

Three working days, then the concrete does its part while you stay off it. I'll walk you through it the same way I do standing in the driveway.

Wednesday, mid-morning. The float goes across before the bleed water comes up.Archival photograph

MondayTear-out

The skid steer breaks the old slab into chunks and they're hauled off the same day. While the ground is open I look at what failed the old driveway, and nine times out of ten it's the same answer: there was almost nothing under it.

TuesdayGrade & form

We cut the ground to depth, bring in the AB3 and pack it in two lifts, set and pin the forms, and tie the rebar up on chairs. This is the day your driveway is actually won or lost, and it's the day nobody takes a picture of. The gravel is the job.

WednesdayPour & finish

Trucks are ordered for first thing. We screed, float, wait on the bleed water like the book says, then broom and edge it. The cure compound goes on before we leave, and Danny has the saw out that same afternoon cutting the joints.

ThenSeven days

Walk on it after 24 hours. Park on it after seven days, not six, and I know it looks ready on day four. We come back once to pull the forms and backfill the edges, and the yard gets raked before we go.

Terms, said out loud

Things I say in every driveway anyway

"Come stand in the driveway with me and I'll point at everything we're going to do before you sign anything."

To every nervous customer, and it works

"The crack you're asking about is the sawed joint doing exactly what we cut it for. Call me if it ever gets wider than a nickel."

Reply to a review, spring 2025

"We turned down three pours this week because the ground was frozen. I'd rather lose the week than stand behind a bad slab for ten years."

Posted every winter, more or less

"You're right that we left the forms on an extra day. I should have called you and I didn't. That one's on me."

Season to date

What this season looks like in numbers

1,840

cubic yards poured since March. The saw needs blades and the truck needs tires, and that's how a good season looks.

212

driveways torn out and repoured across the metro, Missouri and Kansas both.

0

pours below 40 degrees and falling, this season and every season since 2004.

That zero is the number I'm proudest of. Cold concrete never reaches strength, and a contractor pouring in December because his calendar is empty is pouring your money into a slab that won't last. When the forecast turns on us, I call you and we move the date. It costs me money every winter. It's still the rule.

Service area

The towns we pour in

Missouri towns and Kansas towns, and it's the same price sheet in both. The yard is in Grandview, so the south metro fills up first, but we pour the whole ring.

  • Kansas City, MO
  • Grandview
  • Lee's Summit
  • Raytown
  • Belton
  • Raymore
  • Blue Springs
  • Independence
  • Overland Park
  • Olathe
  • Lenexa
  • Shawnee
  • Leawood
  • Prairie Village
  • Merriam
  • Mission
  • Gladstone
  • Liberty
  • North Kansas City
  • Parkville
  • Grain Valley
  • Oak Grove
  • Peculiar
  • Harrisonville

If you're outside that ring, call anyway. Short-load fees make small far-out jobs expensive, and I'd rather tell you that on the phone than on an invoice.

How to reach Curt

There's no contact form on this website

Because the phone is faster and I answer it. Measure the length, measure the width, and tell me what's there now. If it's loud when I pick up, that's the saw, and I'll still hear your numbers fine.
