The PAR1 Resin Bolt is a resin anchored yielding bolt designed to suit a range of application from quasi-static through to dynamic and squeezing ground conditions.
The two paddle sets of the PAR1 Resin Bolt assist in the mixing of resin during installation and act as anchors once the resin is set. The PAR1 Resin Bolt is supplied in Ø20 mm or Ø22 mm diameter bar depending on support requirements.
The optional tri-lobe tip of the PAR1 Resin Bolt aids in the centralization of the anchor as well as the piercing and shredding of the resin cartridge to mitigate gloving. The unique paddle design maximizes load transfer between the installed bolt and the surrounding rockmass through the resin interface. The proximal paddle set transfers load into the rockmass at the head of the rockbolt to minimise faceplate loading.
