LIEBIG Anchors

LIEBIG is renowned for its heavy-duty concrete anchors, which are engineered for safety-critical and high-performance applications. The flagship product, the LIEBIG ULTRAPLUS, is an undercut anchor that stands apart from conventional fasteners. Instead of relying on friction, it creates a positive mechanical interlock within the concrete. This is achieved by first drilling a hole, then using a special tool to create an "undercut" or wider void at the bottom. As the anchor is installed, a spring-loaded mechanism expands its keys into this void, locking it securely. This method provides superior resistance to very high loads, including dynamic, shock, and seismic forces, and it significantly reduces stress within the concrete, allowing for smaller edge distances and spacing.

Other notable products in the LIEBIG range of heavy-duty concrete anchors include the self-undercutting SUPERPLUS, which does not require a special tool for undercutting, and the Safety Bolt, a double expansion anchor that provides increased security. These fasteners, sometimes referred to as LIEBIG bolts or LIEBIG fixings, are trusted by engineers and contractors for securing structural steelwork, machinery, and other critical installations in demanding environments. Their unique design and proven performance, validated by European Technical Approvals (ETA), make them a go-to solution for projects where absolute reliability is non-negotiable, such as in power plants, industrial facilities, and civil engineering projects.
