Abstract
A two component resin capsule is disclosed for grouting an anchor element in a predrilled hole. More specifically, a flexible resin capsule is provided which may be wound on a reel and fed into a predrilled hole of any length. The resin capsule includes a plurality of pairs of sealing clips which enable the capsule to be severed intermediate any one of these pairs, thereby providing a capsule having a length corresponding to the length of the predrilled hole. The resin capsule, formed from a frangible material, includes a resin and a hardener housed in discrete compartments. The capsule is placed in a bolt hole such that when an anchor bolt is inserted, the capsule ruptures enabling the contents to mix and harden thereby achieving a secure resin bolting system.
