A tie rod support having a lightweight rod of fiber reinforced plastic (FRP) material with a tapered sleeve of non-ferrous material mounted on one end. The other end of the rod is adapted to be inserted axially into a hole in a wall or roof of a mine with the sleeve supporting a pressure plate abutting the inner surface of the wall or roof. Frangible cartridges of polyester resin and a catalyst are first inserted in the hole and axial rotation of the rod as it is inserted into the hole ruptures the cartridges and mixes their contents, causing rapid curing of the resin and a bond between the FRP rod and the inner surface of the hole.
