Pre-Pour Inspection

Foundation Phase Inspection • Before Concrete Placement

Checks foundation forms, rebar placement, plumbing penetrations, and grading before concrete is poured. The goal is to catch issues while they're still straightforward to fix — before the slab locks everything in place.

When it occurs

Timing: before the slab is poured — after foundation preparation is sufficiently complete to inspect, but before concrete placement.

Pre-pour work is evaluated against applicable building codes for foundation and underground plumbing at this stage. I hold ICC R5 (Residential Combination Inspector) certification and am a TREC Professional Inspector #24271.

Inspector reviewing printed general foundation notes at a new construction site.
Comparing field conditions to the engineer's foundation notes and post-tension specifications.

What's observable before the pour

At this stage, I can typically observe and document:

  • Form placement and alignment
  • Form elevation — checked with a Zip Level® before the pour, while differences can still be identified and addressed
  • Reinforcing steel (rebar) size, spacing, and placement
  • Plumbing penetrations and stub-outs before they're buried
  • Vapor/moisture barrier presence and condition, where used
  • Site grading and drainage slope around the forms
  • General sub-grade/soil prep conditions visible prior to the pour
Zip Level elevation-measurement device set up on a foundation form before a concrete pour.
Checking form elevation with a Zip Level® before the pour — the last practical chance to catch and correct differences before concrete sets the finished grade.
Tape measure checking post-tension cable spacing over a vapor barrier before concrete placement.
Checking tendon spacing before the pour.
Plumbing pipe penetration sealed with tape through a vapor barrier before a concrete pour.
A plumbing penetration through the vapor barrier — visible now, buried once concrete is placed.

What becomes concealed after concrete placement

Once concrete is placed, these conditions are no longer observable:

  • Rebar position and coverage within the slab
  • Condition and placement of any vapor barrier or under-slab insulation
  • Under-slab plumbing runs and conduit/utility routing
  • Sub-grade soil conditions directly beneath the slab

That's why timing matters — and why a pre-pour inspection is a distinct opportunity from a later phase or a final inspection.

Examples from actual pre-pour inspections

A few conditions from inspections I've performed — the kind of thing that's visible now and won't be after the pour.

Close-up of torn sheathing on a post-tension cable before a concrete pour.
Damaged protective sheathing on a post-tension tendon. Exposed sheathing lets concrete bond directly to the tendon, which can interfere with proper tensioning. This was flagged for repair while the tendon was still accessible — not something you can catch once concrete is placed.
Rebar dowels crossing at a foundation edge form before a concrete pour.
A missing tie wire at a rebar intersection. Reinforcing steel needs to stay tied in position for the pour — this could be corrected while it was still accessible, before concrete locked it in place.

Scheduling and builder coordination

The builder controls the construction schedule and tells you when the home is ready for a pre-pour inspection. You coordinate the inspection window with the builder. Contact me as soon as the builder provides that window — I need access after foundation preparation is ready but before concrete is poured.

Pricing

Pre-pour inspections use the same home-inspection pricing model — starting at $230+ for homes up to 1,500 sq ft and less than 2 years old. See inspection pricing for details.

Limitations

A pre-pour inspection is not an engineering analysis, design verification, structural certification, or code-official authority inspection. It does not guarantee future foundation performance. I document observable conditions at this stage from the buyer's perspective.

FAQs

What is checked during a pre-pour inspection?

Pre-pour checks typically include foundation form work, rebar placement, plumbing penetrations, and grading/drainage setup before the concrete is poured.

When should a pre-pour inspection happen?

Right before the slab is poured — after the builder has forms, rebar, and plumbing in place, but before concrete goes in.
