Abstract
An improved method of installing tensional anchor bolts or cable bolts into a geological or man made formation by preheating anchor bolts or cables prior to inserting them into a borehole, mixing the bonding material within the borehole by rotating the bolt and allowing curing of the bonding material prior to the cooling of the bolt, thereby placing the bolt under tension and the formation into compression, is provided.
