An undercut anchor, developed by Spit Fixings for use in the Channel Tunnel, is now available for other contracts.The new anchor combines rated load capacities of 17.2 kN tensile, 20.3 kN oblique and up to 26.7 kN shear with facilities for mastic injection after setting and removal for periodic inspection.The Spit Ring anchor can be used where safety is important, where vibration could cause expansion anchors to slip, and where hot, damp and saline conditions could create corrosion risks. Typical applications include railway tunnel refurbishment, installation of high impact safety barriers on motorways, coastal defenses and power stations.Where cost is more important than aesthetic appeal, the new anchors have an advantage over stainless steel expansion anchors, because their cost is at least 50 per cent lower.Although installation is claimed to be simple, Spit provides a full on-site product support service for this anchor.
