What Your Concrete Supplier Needs Before a Pour

What Information Your Concrete Supplier Needs Before a Pour

Planning a successful concrete project starts long before the first ready-mix truck arrives. Whether you’re building a commercial foundation, pouring a residential driveway, installing sidewalks, or completing a warehouse slab, your concrete supplier can only deliver the right product if they have the right information.

Unfortunately, many project delays, wasted concrete, and unexpected costs happen because critical details were never discussed before the pour. A professional supplier doesn’t just deliver concrete—they help ensure your project runs smoothly from start to finish.

At 28 Concrete, we work with contractors, builders, developers, and homeowners throughout Denver, Colorado; Aurora; Commerce City; Englewood; and surrounding communities. The better we understand your project before delivery, the better we can provide the right mix, the correct quantity, and dependable scheduling.

If you’re preparing for an upcoming concrete pour, here’s exactly what your supplier needs to know.

1. The Type of Project

The first question every concrete supplier asks is simple:

What are you pouring?

Different projects require different concrete mixes and performance characteristics.

Examples include:

Residential driveways
Sidewalks
Garage floors
Basement slabs
Foundations
Warehouse floors
Parking lots
Loading docks
Curbs and gutters
Retaining walls
Footings
Structural columns

A driveway doesn’t require the same concrete as a commercial loading dock. Likewise, a warehouse floor has completely different strength and finishing requirements than decorative residential concrete.

Knowing the project type allows your supplier to recommend the proper mix design.

2. Required Concrete Strength (PSI)

Concrete strength is measured in PSI (Pounds per Square Inch).

Common strengths include:

3000 PSI
3500 PSI
4000 PSI
4500 PSI
5000 PSI and above

If your engineer or architect has specified a required strength, provide that information before ordering.

If you’re unsure which strength is appropriate, an experienced supplier can guide you based on the intended use.

Choosing the wrong PSI can create expensive structural issues later.

3. Total Volume Needed

One of the most important pieces of information is the amount of concrete required.

Concrete is ordered in cubic yards.

To calculate volume accurately, you’ll need:

Length
Width
Thickness

Ordering too little means delaying the project while waiting for another truck.

Ordering too much means paying for unused concrete.

Professional suppliers can help verify your calculations before scheduling delivery.

4. Exact Delivery Address

Every delivery begins with knowing precisely where the truck is going.

Include:

Full street address
Jobsite entrance
Gate codes, if necessary
Building numbers
Lot numbers for new developments

Construction sites often have multiple entrances. Clear directions help prevent delays and confusion.

This is especially important for projects throughout Denver, Colorado, Commerce City, and rapidly developing neighborhoods around Aurora, in concrete delivery service areas.

5. Jobsite Accessibility

Not every ready-mix truck can reach every location.

Your supplier should know:

Width of entrances
Low power lines
Tight turns
Weight restrictions
Muddy conditions
Steep grades
Overhead obstacles
Distance from truck parking to pour location

If trucks cannot safely access the pour location, additional equipment may be required, including:

Concrete pumps
Conveyor systems
Georgia buggies
Wheelbarrows

Knowing this beforehand avoids costly delays.

6. Desired Slump

Slump measures concrete consistency.

A higher slump creates more workable concrete.

A lower slump creates stiffer concrete.

Different projects require different slump ranges depending on:

Reinforcement
Placement method
Finishing requirements
Weather conditions

Never assume that adding water at the jobsite is the solution.

Too much water can significantly reduce concrete strength and durability.

Instead, discuss your workability needs with your supplier before the mix is produced.

7. Air Entrainment Requirements

Colorado weather can be extremely hard on concrete.

Freeze-thaw cycles make air-entrained concrete essential for many exterior applications.

Examples include:

Driveways
Sidewalks
Patios
Parking lots
Exterior slabs

Air entrainment helps reduce cracking and scaling caused by freezing moisture.

If your project is outdoors, be sure to discuss whether air entrainment is required.

8. Reinforcement Details

Although reinforcement is usually handled by the contractor, your supplier benefits from understanding the overall design.

Examples include:

Rebar
Wire mesh
Fiber reinforcement
Post-tension systems

Some concrete mixes perform differently depending on reinforcement methods.

Fiber-reinforced concrete may also reduce cracking in certain applications.

9. Weather Conditions

Colorado weather changes quickly.

Before scheduling delivery, discuss expected conditions including:

High temperatures
Cold temperatures
Wind
Rain
Snow
Overnight freezing

Weather directly affects:

Setting time
Finishing
Curing
Pumpability

Experienced suppliers often adjust admixtures based on seasonal conditions to help maintain performance.

10. Desired Delivery Time

Concrete is a time-sensitive product.

Once batching begins, timing matters.

Tell your supplier:

Exact start time
Number of finishers
Pump schedule
Inspection schedule
Crane availability, if applicable

Poor scheduling can leave trucks waiting unnecessarily or crews waiting for concrete.

Both situations increase project costs.

11. Number of Trucks Required

Large commercial projects often require multiple trucks.

Your supplier needs to know:

Total yardage
Desired spacing between trucks
Pump production rate
Crew capacity

Proper scheduling ensures a continuous pour without cold joints or unnecessary interruptions.

12. Pump or Direct Chute Delivery

Can the truck back directly to the forms?

Or will a concrete pump be required?

Your supplier should know the placement method because it affects:

Mix consistency
Scheduling
Truck sequencing
Equipment coordination

Concrete pumps are common on projects with limited access or elevated placements.

13. Special Admixtures

Many projects benefit from specialty admixtures.

These may include:

Accelerators
Retarders
Water reducers
Superplasticizers
Corrosion inhibitors
Shrinkage reducers

Each serves a different purpose depending on project conditions.

Discuss these needs before batching begins.

14. Finishing Requirements

The finished surface influences the concrete mix.

Examples include:

Broom finish
Smooth trowel finish
Decorative stamping
Exposed aggregate
Polished concrete

Different finishing techniques may require different workability characteristics.

Sharing these plans helps your supplier recommend the best mix.

15. Testing Requirements

Many commercial projects require quality testing.

These may include:

Slump testing
Air content testing
Temperature checks
Compression cylinders
7-day strength testing
28-day strength testing

Inform your supplier if testing will be performed so everyone is coordinated on-site.

16. Contact Information

Always provide:

Project manager
Superintendent
Contractor
Pump operator
Backup contact

If weather changes or traffic affects delivery, your supplier needs someone who can make immediate decisions.

Good communication prevents unnecessary delays.

Why Early Communication Saves Money

Sharing complete project information benefits everyone involved.

It helps:

Reduce waste
Prevent incorrect mix orders.
Improve scheduling
Avoid expensive downtime
Deliver better finished concrete.
Increase jobsite safety
Improve overall project quality.

The most successful concrete projects begin with planning—not guessing.
