Post-Slab Pour Inspection

3rd-Party Slab Evaluation for Builders (Arizona ROC Tolerance Focus)

Once concrete is placed, the slab becomes the foundation for everything that follows. Our Post-Slab Pour Inspection provides builders with an independent evaluation of slab performance based on Arizona ROC allowable tolerancesfor level, flatness, waviness, shrinkage cracking, and surface quality.

This inspection is performed after the slab is poured but before framing begins—the ideal time to catch issues early and document conditions for quality assurance.

Why Builders Use Post-Slab Inspections

 

  • Verifies slab conditions meet Arizona Registrar of Contractors (ROC) standards
  • Protects against future structural, flooring, and finish problems
  • Reduces warranty claims from homeowners
  • Creates a documented “baseline condition” before vertical build-out
  • Provides clarity when concrete performance is questioned
  • Supports your QA/QC program with measurable, photo-based reporting

 

What We Evaluate (Post-Slab Pour)

 

Levelness & Flatness

Measured against ROC allowable tolerances:

  • Variations in elevation
  • Acceptable flatness/unevenness limits
  • Waviness and localized dips or humps
  • Surface transitions between rooms or structural areas

Concrete Cracking

Assessment of all crack types using ROC and industry standards:

  • Shrinkage cracks
  • Surface checking
  • Map cracking
  • Location, width, and length
  • Determination of whether cracks meet allowable tolerances or require corrective action

Surface Defects

  • Spalling, scaling, or flaking areas
  • Trowel marks and surface irregularities
  • Honeycombing at edges
  • Expansion and control joint condition
  • Proper execution of saw cuts

Structural & Perimeter Review

  • Slab edges and turn-downs
  • Garage slope and drainage
  • Stem walls and cold joints
  • Anchor bolt placement (if visible pre-framing)
  • Visible signs of heaving or settling

Deliverables You Receive

 

  • Detailed ROC-based evaluation of slab condition
  • High-resolution, annotated photos
  • Clear determination of within tolerance / out of tolerance
  • Recommendations for repair, monitoring, or acceptance
  • Documentation suitable for builder files and warranty protection

This inspection can be performed any time after the slab cures but is most effective when completed before framing begins, allowing unrestricted visibility across the entire concrete surface.

Why Builders Trust Us

 

  • Inspectors trained specifically in Arizona ROC slab tolerances
  • Fast scheduling with quick turnaround reports
  • Clear, objective findings—no ambiguity, no drama
  • Professional documentation for builders, supers, and QA managers
  • Experience working with high-volume and custom home builders
