ASTEC™ FRP Active Anchors

Ground anchors ASTEC Active Anchors

FRP post-tensioned anchoring solution

An Active Anchors 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.

A typical application for Active Anchors is anchoring of retaining walls during excavation works. To prevent the wall from the smallest displacement, the anchor is pre-loaded.

ASTEC Active Anchors is made of composite material, which is by nature cut-able. The tendons can be excavated by any standard equipment, therefore anchor removal is never required.


Product features

  • A standard Bartec® connection is made of a parallel-thread rebar coupler and two bars whose end have previously been enlarged before being threaded: thus the cross section of the bar isn’t reduced.
  • Solution supported by 3 high-productivity machines which prepare each bar in sequence: clean square cutting > bar end enlarging by cold forging > threading.
  • Thread on the rebar can be extended from a half-coupler to a full coupler length, allowing to use the very same coupler for positional applications (no need to rotate bars to perform the connection).

  • Simplify your inventory: A single standard coupler for most applications.
  • No reduction of cross-section area of the bar, making your coupler connection a strong point of the structure.
  • Working in tension/compression thanks to its parallel-thread technology.
  • Joints verified by visual inspection with no requirement to induce a specific torque value.
