Active Steel Anchor based on Fully threaded bars
An Active Anchor is post-tensioned from the external face of the ground immediately after installation and is usually designed to help prevent deformation of the ground or retained structure. It has a free length and a bonded length.
Steel Active Anchors are the preferred solution for excavation works where post-tensioning is required.
• Suitable for any temporary or permanent work as long as tendons do not encroach onto neighboring plots and do not need to be cut or extracted at a later stage.
• Wide range based on high-tensile fully threaded bars available in different grades and 25 diameters up to 63.5mm. High steel grades may be preferred to ease handling and reduce the bored hole diameter.
• Corrosion protection accessories (DCP) are part of the system and can be supplied by Dextra.
