Find the cause: wrong diameter, weak base, spinning plug or over-tightening. A bigger plug may make damage worse.
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
Move the point with proper spacing or use an approved repair method. Follow preparation and cure times for injection systems.
Common mistake
Do not pack the hole with timber, paper, general adhesive or debris.
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?
