Abstract: A ready to use composite anchor plug kit, pre-assembled with adhesive/s or compounds (20, 21) and spill catchment film (11), which does not need separate adhesive/s or compounds to be inserted, injected or applied in or on the body of the anchor plug for the purposes of increasing the resultant anchoring strength. The anchor plug has a detachable, adhesive backed, spill containment and collection film (11) designed to protect the immediate surrounding surface work area from the extra adhesive (20, 21) seeping out. The adhesive (20, 21) overspill is collected on the film surface, which can be detached & discarded, thereby ensuring a neat & clean uncontaminated area around the anchored borehole. The body of the anchor plug (16) is sealed with a pressure retaining diaphragm seal plug (15) with self-sealing, leak-proof properties, designed to retain the generated pressure within the cavity of the anchor plug (16), after it is pierced and threaded through with an anchor.
