✅ Pre-Pour Concrete Checklist

Use this checklist before every concrete pour to ensure quality, safety, and compliance.

Why Pre-Pour Checks Matter

Pre-pour inspections prevent:

Rejections - Failed inspections mean removal and repour
Cost overruns - Fixing issues after pour is expensive
Schedule delays - Failed pours delay entire project
Safety issues - Proper prep prevents accidents

The Golden Rule

If you're not sure, don't pour. It's easier to fix before concrete than after.

24-48 Hours Before Pour

Subgrade Preparation

Subgrade compacted - No soft spots, proper density
Moisture content correct - Not too wet, not too dry
Grade checked - Elevations match plans
Slope verified - Drainage slopes correct
Vapor barrier installed (if required)
Gravel base installed (if required)
Reinforcement supports - Chairs, bolsters in place

Forms & Reinforcement

Utilities & Penetrations

Conduit installed - Electrical, data, etc.
Plumbing penetrations - Pipes, sleeves in place
HVAC penetrations - Ductwork, sleeves
Embedded items - Anchor bolts, inserts, plates
Expansion joints - Location and type correct
Control joints - Location marked (if saw-cut later)

Day of Pour

Weather Check

Temperature forecast - Above 40°F (or protection plan)
No rain expected - Or protection plan ready
Wind conditions - Not too windy for finishing
Sun protection - Shade or covers if hot
Frost protection - Heaters ready if needed

Equipment & Materials

Concrete ordered - PSI, slump, mix design confirmed
Truck access verified - Can reach pour location
Pump truck arranged (if needed)
Vibrators ready - Working, clean, operators trained
Finishing tools ready - Screeds, floats, trowels
Curing materials ready - Curing compound, blankets, etc.
Testing equipment ready - Slump cone, cylinders, etc.

Site Preparation

Access routes clear - Trucks can get in/out
Pour area clean - No debris, standing water
Forms clean - No mud, debris inside forms
Rebar clean - No mud, oil, rust
Water source available - For cleanup, curing
Washout area prepared - For truck cleanup

Safety

Safety briefing conducted - Pour crew informed
PPE available - Boots, gloves, eye protection
Barricades installed - Keep non-essential personnel away
Traffic control - If near roads or traffic
Fall protection - If working at height
First aid kit - On site and accessible

Final Pre-Pour Inspection

Forms

Forms tight - No gaps, no leaks
Forms level - Top of form at correct elevation
Forms plumb - Vertical forms straight
Forms braced - Adequate bracing for concrete pressure
Form oil/release applied - If reusing forms

Reinforcement

Rebar size correct - Matches plans
Rebar spacing correct - Matches plans
Rebar cover adequate - Minimum per code (usually 3")
Rebar tied securely - Won't move during pour
Lap splices correct - Length and location per code
Wire mesh installed (if required) - Proper overlap

Subgrade

Subgrade compacted - No soft spots
Grade correct - Elevations match plans
Moisture appropriate - Not too wet, not too dry
Clean - No debris, standing water, mud

Embedments & Penetrations

Anchor bolts - Location, size, height correct
Sleeves - Location, size correct
Inserts - Location, type correct
Conduit - Location, size correct
Expansion joints - Location, type correct

Testing

Test cylinders ordered - 2-3 cylinders per pour
Slump test equipment ready - Cone, rod, base plate
Air content test (if required) - Air meter ready
Temperature test - Thermometer ready

During Pour

First Truck

Slump test performed - Within spec (usually 3-5")
Temperature checked - Within acceptable range
Air content tested (if required) - Within spec
Cylinders made - 2-3 cylinders for testing
Concrete placed - Not dropped from height
Concrete vibrated - Proper consolidation
Concrete screeded - To correct elevation

Quality Checks

No segregation - Concrete uniform
Proper consolidation - No honeycomb, voids
Rebar not displaced - Stays in position
Forms holding - No bulging, leaking
Elevation correct - Top of concrete at right height

Post-Pour (Immediate)

Finishing

Screeded - To correct elevation
Bull floated - Initial smoothing
Edged - Clean edges around forms
Joint tooled - Control joints cut/tooled
Final finish - Broom, trowel, etc. as specified

Curing

Curing started - Within 30 minutes of finishing
Curing method - Compound, blankets, water, etc.
Curing duration - Minimum 7 days (or per spec)

Protection

Protected from traffic - Barricades, signs
Protected from weather - Covers if needed
Protected from damage - No heavy equipment nearby

Common Mistakes to Avoid

Mistake	Consequence	Prevention
Pouring on wet subgrade	Settlement, cracking	Check moisture, wait if needed
Wrong PSI mix	Rejection, removal	Verify mix design before ordering
Inadequate form bracing	Form failure, blowout	Over-brace, check calculations
Insufficient rebar cover	Code violation	Use chairs, check before pour
Pouring in bad weather	Poor finish, cold joints	Check forecast, protect if needed
Not testing slump	Wrong consistency	Test first truck, every truck if needed
Not making cylinders	Can't verify strength	Make cylinders before finishing

Quick Reference: Minimum Cover

Location	Minimum Cover
Footings	3"
Walls	3" (exposed to earth)
Slabs	3/4" (not exposed to weather)
Slabs	1-1/2" (exposed to weather)
Beams/Columns	1-1/2"

Don't Rush

A failed pour costs 10x more than waiting a day to fix issues. Take the time to check everything before pouring.
