Pre-Pour Concrete Checklist: A Field Walkdown Before the First Truck
A systematic pre-placement inspection covering access, forms, grades, subgrade, reinforcement, embeds, weather, testing, finishing, and curing.
Editorial review: 2026-09-29 · How we review technical content
Key takeaways
- Confirm truck route, pump location, overhead/underground hazards, washout, lighting for late work, crew access, concrete quantity, delivery interval, backup equipment, and communication with the plant. Ensure the crew can place and finish at the ordered rate.
- Check excavation/subgrade elevation, uniformity, compaction records if required, standing water, mud, frost, and vapor retarder condition. Verify forms for line, grade, dimensions, bracing, release agent, cleanliness, and openings.
- Verify bar/mesh size, spacing, cover, supports, laps, dowels, chairs, anchors, and congestion. Confirm inspection approval where required. Prepare testing equipment/agency, sample location, cylinder curing area, and documentation.
Site and logistics
Confirm truck route, pump location, overhead/underground hazards, washout, lighting for late work, crew access, concrete quantity, delivery interval, backup equipment, and communication with the plant. Ensure the crew can place and finish at the ordered rate.
Review weather beyond temperature: wind, rain, humidity, freezing risk, and sun can change placement and curing plans.
Receiving surface and forms
Check excavation/subgrade elevation, uniformity, compaction records if required, standing water, mud, frost, and vapor retarder condition. Verify forms for line, grade, dimensions, bracing, release agent, cleanliness, and openings.
Confirm drains, sleeves, blockouts, construction joints, waterstops, and embedded plates are located and secured.
Reinforcement and testing
Verify bar/mesh size, spacing, cover, supports, laps, dowels, chairs, anchors, and congestion. Confirm inspection approval where required. Prepare testing equipment/agency, sample location, cylinder curing area, and documentation.
Photograph concealed work after inspection and before concrete.
Finish, joints, and curing
Agree on screed elevations, finish type, joint layout/saw timing, edge details, curing method, protection, and who is responsible for each step. Put curing materials, blankets, saws, backup fuel, and weather protection on site before the pour.
A five-minute walkdown before the first truck can prevent hours of improvisation after concrete is already setting.
Field checklist
- Confirm access, quantity, truck rate, and washout.
- Inspect support/forms/vapor retarder.
- Inspect reinforcement and embeds.
- Prepare testing.
- Plan finish, saw cuts, cure, and weather protection.
