Concrete contract template
Concrete is the one trade where you tell the customer, honestly, that the finished product will crack. A good contract explains why, says how control joints manage it, and sets out everything that decides how long the slab lasts: the base, the thickness, the mix, the reinforcement, the finish and the curing. This template covers driveways, patios, walks and slabs. Read it below, then send it from SignMaster.

Concrete Contract
This Concrete Contract (the "Contract") is made on Contract date between Concrete company name, license number License number (the "Contractor"), and Customer name (the "Customer").
1. The property
The work will be done at Job address. The Customer confirms they own the property or have the owner's permission for this work.
2. The work
- What will be poured: Pour description.
- Area: about Area in square feet square feet.
- Thickness: Thickness in inches inches; thickened edges or other details: Thickened edges and details.
- Mix: Mix strength in PSI PSI concrete, Mix details.
- Removal of the existing surface: Removal of existing surface.
3. Base and reinforcement
The Contractor will excavate to grade and install Base material and depth, compacted before the pour. Reinforcement: Reinforcement. If the soil below is soft, wet or full of roots or organic material, the Contractor will tell the Customer and price the extra excavation and base before going on. Where digging goes below surface grading, the Contractor will request an 811 utility locate first; the Customer will mark private lines such as sprinklers and lighting cables.
4. Finish and joints
Finish: Finish. Pattern and color chosen by the Customer, if any: Pattern and color chosen. Control joints will be cut or tooled about every Control joint spacing in feet feet, with expansion material where the slab meets the house, steps or other structures.
5. Slope and drainage
The slab will slope Slope direction so water drains away from buildings, as far as the site allows. Water standing less than Puddle depth allowed deep after rain stops is normal and is not a defect.
6. Cracking and color
Concrete shrinks as it cures and will develop some cracks. Control joints are there to keep most of them in the joints, but cracks can still form between joints. Hairline cracks, small surface cracks, and differences in color or texture between pours, sections or samples are normal and are not defects, especially in colored, stamped and exposed-aggregate finishes.
7. Schedule and weather
The pour is planned for on or about Estimated pour date. The Contractor will not pour on frozen ground or when heavy rain or freezing temperatures are expected during early curing, and may reschedule for weather without penalty.
8. Truck access and the site
Concrete trucks, pumps and equipment will use this route: Access route for trucks. Heavy trucks can damage lawns, curbs, sprinkler lines and existing paving along the route. The Contractor will take reasonable care, and repair of damage along the agreed route is handled as follows: Route damage arrangement.
9. Curing, care and sealing
The Customer will keep people off the new concrete for Foot traffic wait in hours hours, cars off for Car wait in days days, and trucks and other heavy vehicles off for Heavy vehicle wait in days days. De-icing salts and chemicals can damage new concrete, so the Customer will not use them on it during its first winter. Sealing is Sealing included or not.
10. Price and payment
The total price is Contract price. A deposit of Deposit is due when this Contract is signed, and the balance is due when the work is complete. Extra excavation, base or reinforcement under section 3 is added by a written change order signed by both parties. Accepted payment methods: Payment methods.
11. Warranty
For Workmanship warranty in years year(s) after completion, the Contractor will repair cracks wider than Crack width covered, edges that become uneven by more than Uneven edge height covered, and settling caused by its base work. The warranty does not cover hairline cracks, color variation, damage from tree roots, ground movement, loads or chemicals the Customer was told to avoid in section 9, or drainage changes made by others. Repairs may not match the color of the original concrete.
12. Cancellation and general terms
If this Contract was signed at the Customer's home, the Customer may have a legal right to cancel within three business days, and the Contractor will provide a written notice explaining how. The Contractor carries general liability insurance and will show proof on request. This Contract is the whole agreement for the work and is governed by the laws of the state of State.

What a concrete contract has to explain
Most concrete complaints are about cracks, color and puddles. Cracks are normal, because concrete shrinks as it cures and control joints decide where it cracks. Color varies between pours and finishes. Puddles depend on the slope you set. If the contract says all that before the truck arrives, a hairline crack six months later is a conversation about the warranty terms, not about whether the job was done right.
The base matters just as much. A slab is only as good as what's under it, and the customer never sees it. Writing down the base material, depth, compaction and reinforcement shows them what they paid for.
What the template covers
- The pour: what's being poured, the area in square feet, thickness, thickened edges and the mix strength in PSI.
- Removal and base: breaking out the old surface, the base material and depth, compaction, and what happens if the soil is soft.
- Reinforcement: rebar, wire mesh or fiber, written down so it can't quietly disappear.
- Finish and joints: broom, smooth, exposed or stamped, the pattern and color the customer chose, and control joint spacing.
- Slope and drainage: which way water runs, and how deep a puddle can be before it counts as a defect.
- Cracking and color: why cracks happen, and that hairline cracks and color differences aren't defects.
- Truck access: the route the truck takes and who repairs lawn, curb or sprinkler damage along it.
- Curing and care: when people, cars and heavy vehicles can use the slab, sealing, and de-icing salt in the first winter.
Concrete contract mistakes
- Promising crack-free concrete. It doesn't exist. Promise joints at a set spacing, and warrant against cracks wider than a stated width or edges that become uneven.
- Leaving thickness and mix blank. A driveway poured thinner than agreed fails early, and nobody can prove it afterward. Write the thickness and PSI into the contract.
- Ignoring the truck's route. A loaded mixer can crack an old driveway or sink into a soft lawn. Agree the route and who pays for damage along it.
- Skipping curing instructions. Driving on a new driveway too soon, or salting it the first winter, leads to cracks and scaling. Hand over the care rules in writing.
- Selling stamped color from a brochure. Colored and stamped concrete varies from samples. Have the customer pick from a real pattern and color, and say it will vary.
Get the care rules signed
Section 9 sets how long to keep people, cars and heavy vehicles off the slab, and warns against de-icing salt in its first winter. When a new driveway scales in March, that signed section is the difference between a warranty claim and a care problem.

Builders and repeat work
If you pour driveways and walks for a home builder, the specs repeat and only the lot and size change. Keep a template with your standard mix, base and finish filled in and bulk send one contract per lot from a spreadsheet, with columns like Job address, Area in square feet and Contract price. See send contracts from an Excel file for setting up the sheet.
Questions? Answers.
Will new concrete crack?
Almost certainly a little. Concrete shrinks as it cures, and control joints are there so the cracks form in straight lines where they won't show. This template's warranty covers cracks wider than a set width or edges that become uneven.
How soon can you drive on a new concrete driveway?
It depends on the mix and the weather, so follow the contractor's instructions; for cars it's often around a week, and longer for heavy trucks. The template has separate blanks for foot traffic, cars and heavy vehicles.
How thick should a concrete driveway be?
It depends on the vehicles and the soil, and local codes or HOA rules may set a minimum. Plan thicker for heavy vehicles. Whatever you agree, section 2 puts the number in writing.
Is sealing included?
Only if the contract says so. Section 9 has a line for sealing, and if it isn't included, the customer knows to plan for it once the slab has cured.
