Distinguish solid brick from hollow units. In hollow masonry, chamber geometry and the exact drilling point affect the result.
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 a product approved for the actual masonry. Hollow units may require controlled expansion or an injection system with a mesh sleeve.
Common mistake
Never transfer concrete ratings to hollow masonry or drill into a joint unless the system expressly permits it.
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?
