V-Head - Joint Repair

Skid Steer Attachment Designed for Longitudinal Joint Repair

  • Remove and replace at deeper depths on the joint line or other targeted areas
  • Requires less material
  • Cuts a V-shape into the pavement that allows the new material to bond better to the existing pavement
  • The tapered cut alleviates the shearing effect that is seen with the flat surface cuts
