Description

Specification
In-place installation (M10 to M24) and pre-positioned installation (M8 to M24)

High loads, minimum spacing and edge distances

The bonded anchor is suitable for cracked concrete (concrete tensile zone) and non-cracked concrete (concrete compressive zone)

The drill holes can be created using a hammer drill (W-VIZ M8 to M24), vacuum drill (W-VIZ M10 to M24) or diamond drill process (W-VIZ M10 to M24)

Hardened chemical injection mortar largely seals off the drill hole

Attachment with low expansion pressure allows minimum spacing and edge distances

Geometry of anchor rod allows safe follow-up expansion capability

Mechanical drill hole cleaning: Easy handling, very good drill hole cleaning, high loads

Safe installation if the specified torque is applied when installing the anchor

Force-controlled/torque-controlled expansion anchors made of stainless steel in sizes M8, M10, M12, M16, M20 and M24

The load is transferred via the mechanical interlocking of individual cones in the injection mortar and also via a combination of retention and frictional forces in the base material (concrete) | In-place installation (M10 to M24) and pre-positioned installation (M8 to M24) | High loads, minimum spacing and edge distances | The bonded anchor is suitable for cracked concrete (concrete tensile zone) and non-cracked concrete (concrete compressive zone) | The drill holes can be created using a hammer drill (W-VIZ M8 to M24), vacuum drill (W-VIZ M10 to M24) or diamond drill process (W-VIZ M10 to M24) | Hardened chemical injection mortar largely seals off the drill hole | Attachment with low expansion pressure allows minimum spacing and edge distances | Geometry of anchor rod allows safe follow-up expansion capability | Mechanical drill hole cleaning: Easy handling, very good drill hole cleaning, high loads | Safe installation if the specified torque is applied when installing the anchor | Force-controlled/torque-controlled expansion anchors made of stainless steel in sizes M8, M10, M12, M16, M20 and M24 | The load is transferred via the mechanical interlocking of individual cones in the injection mortar and also via a combination of retention and frictional forces in the base material (concrete) | Notice | Suitable injectable mortar: WIT-VIZ, WIT-VIZ Express | European technical assessment ETA-04/0095 for fixing point option 1, cracked and non-cracked concrete, seismic performance category C1 and C2
