Define the load and concrete first
Do not select an anchor by diameter alone. Loads, group layout, vibration, cracked or uncracked concrete, member thickness and exposure all affect selection.
Use the exact product's technical data and installation instructions. Safety-critical anchorage requires design approval by a qualified engineer.
Verify edges, spacing and embedded items
Minimum edge distance, anchor spacing and concrete thickness come from the approved design and product assessment, not a universal site rule.
Scan for reinforcement, post-tensioning and services. Do not cut reinforcement or move a hole without technical approval.
Drill a controlled hole
Use the specified bit diameter, hole depth and drilling method. Check bit wear, maintain alignment and verify depth.
Do not widen the hole by levering the drill or force an anchor into a shallow hole. Alternative drilling methods must be explicitly permitted.
Control concrete dust
Concrete drilling can generate respirable crystalline silica. Use suitable source controls, extraction and work practices for the task.
Separate the area and select eye, hearing and respiratory protection from the risk assessment; PPE complements rather than replaces dust control.
Clean in the specified sequence
Follow the stated blow-brush-blow cycles with the correct brush and approved pump, compressed air or vacuum method.
Check that the brush reaches the bottom and remains serviceable. Do not assume wet holes or contaminated holes are acceptable.
Set and torque correctly
Install without damaging threads or coating and confirm embedment, washer arrangement and full plate bearing.
Use the product-specific torque with a suitable calibrated torque wrench. More torque is not safer, and impact tools are acceptable only when the specified method allows them.
Inspect and document
Check identity, position, spacing, embedment, hardware, bearing and concrete condition. Stop when cracking, spalling or anchor rotation is observed.
Record the anchor, drilling and cleaning methods, torque, tool identity, inspector and approved corrective actions.
