Density varies and excessive expansion can crush the base. Check block thickness and surface condition.
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 large-bearing or dedicated fixing, often with non-hammer drilling and controlled tightening.
Common mistake
Do not use ordinary concrete values or tighten until the material crushes.
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?
