Confirm the drill reaches concrete rather than thick render. Consider edges, reinforcement, base grade and member thickness.
Method basis: Rigips/Knauf system guidance and Fischer/Hilti fixing-selection principles. Final parameters always come from the selected product data.
How to plan the installation
Use the specified diameter and cleaning procedure. Respect edge spacing, embedment, torque and cure time.
Common mistake
Do not cut reinforcement without engineering approval or simply enlarge a damaged hole.
Pre-start check
- Was the structural base identified rather than only the finish?
- Does the weight include contents and projection?
- Were services, edges and minimum spacing checked?
- Does the product data permit the base, direction and environment?
