Technique

Stressed Anchors

Stressed Anchors are ground anchor systems designed to actively resist applied loads by pre-tensioning the anchor tendon after installation. Unlike passive anchors, which rely solely on bond or friction, stressed anchors are deliberately tensioned to provide immediate support to retaining structures, excavations, slopes, or foundations.
