Chemical Anchor

1. Chemical Anchor Solutions
   Onyx Engineering offers expert chemical anchoring for secure, code-compliant anchorage in concrete and masonry. Our epoxy, polyurethane, and cementitious grout anchors are installed by trained technicians using validated methods to achieve reliable bond strengths and durable performance in retrofit, seismic, and new-construction applications. We prioritize substrate preparation, quality control, and safety to ensure long-lasting connections for structural elements, equipment anchors, and retrofit installations.

Key benefits

• High bond strength across a range of substrates
• Versatile solutions: epoxy, polyurethane, and cementitious grout anchors

Typical applications

• Retrofit connections in concrete and masonry structures
• Seismic anchor upgrades and retrofit ties

1. Overview:

Our Chemical Anchor service delivers engineered fastening solutions for critical connections in new builds and retrofits. We follow recognized standards, validate substrate conditions, and perform bond strength testing to confirm performance. From initial assessment to post-installation inspection, Onyx ensures installations meet design intent, code compliance, and project schedules.

What we do

• Site assessment and substrate evaluation: concrete mix, substrate condition, moisture, and alkalinity checks
• Product selection: epoxy, polyurethane, or cementitious grout anchors matched to load requirements and environmental exposure
• Surface preparation: cleaning, profiling, and moisture mitigation to ensure optimal bond
• Installation methods: controlled drilling, adhesive injection, cure-time management, and cure-in-place procedures
• Verification and testing: pull-out or shear tests, coverage checks, and documentation
• Safety and environmental controls: PPE, ventilation, spill containment, and waste disposal
