Rock bolt is in many ways a typical combination mechanical bolt, installed as a temporary rock support and later grouted to become permanent. But there are important differences. It’s quick and easy to install, simple to grout even with varying consistency and the polypropylene sleeve seals the bolt against corrosion.
