Rock Anchors

Rock Anchors

The Freyssibar prestressing bars, thanks to being threaded over the full length of the bar, are ideally suited for use as ground and rock anchors, fulfilling the requirements of international standards. Lengths over 12 m can be obtained by means of couplers whilst the bar, ducting accessories and the anchorage corrosion protection systems are adjusted to suit the full design life time of the anchor: temporary or permanent. In addition, the anchors can be fitted with injection tubes to fill the bore hole and reinjection tubes to improve the bonding to the substrate.
