First Claim
Patent Images
1. An anchor for a structure having a surface adjacent an anchor medium, including:
- a borehole in the anchor medium adjacent the structure;
including;
a top;
a length of roving comprising a bundle of filaments of high tensile strength partly disposed within said borehole including;
a free end protruding from said top of said borehole;
said filaments of said free end splayed on the surface of the structure;
adhesive attaching said splayed filaments of said free end of said roving to the surface of the structure; and
backfill material filling said borehole and surrounding said roving such that said roving is anchored against removal from said borehole.

Abstract
Anchor 10 for reinforcing a structure against displacement forces and a method of installation includes drilling a borehole 50 in an anchor medium 110 adjacent the structure A length of roving 21 composed of filaments 24 is doubled and pushed into borehole 50 with free end 23 of roving 21 protruding. Backfill grout 41 or resin 42 is pumped or poured into bore hole 50 to embed roving 21 Filaments 24 of free end 23 are spread apart and attached to the structure by adhesive.
