Why are SPECIAL EPOXY INSPECTIONS needed?

1. Safety-Critical Applications

Post-installed epoxy anchors are often used in structural applications (e.g., seismic retrofitting, supporting beams, equipment anchorage). Failure could lead to structural collapse or serious injury, so verifying proper installation is vital.

2. Installation Sensitivity

Epoxy anchors are highly sensitive to installation variables such as:

  • Hole diameter and depth

  • Cleaning procedures

  • Adhesive mixing

  • Improper technique can drastically reduce bond strength, making inspection necessary to ensure compliance with manufacturer specs.

3. Code Compliance (IBC & ACI)

The International Building Code (IBC) and ACI 318 require special inspection for post-installed anchors in many structural applications. These codes mandate inspection to verify proper adhesive anchor installation, especially under sustained loads or in seismic zones.

4. Accountability and Quality Assurance

Having an independent, certified special inspector provides third-party verification that the installation meets design intent and manufacturer instructions. This improves quality control, helps avoid costly failures, and protects all parties (engineer, contractor, owner).
