Elite Precast provides access to its Stability & Loadings Directory to support safe and compliant design.
⚠️ Important: All fire protection walls must be checked and approved by a qualified structural engineer prior to installation.
Installation and Safety Guidance
Construct on a suitable, level and stable base
Avoid direct impact from mobile plant where possible
Inspect blocks and lifting pins before use
Consider strapping top layers in high-risk or high-traffic areas
