Abstract: A method for installing poles in rock surface which includes the step of firstly drilling an annular hole in a rock. The annular hole being drilled such that a centrally positioned core of rock remains extending upwardly through the annular hole. Next, a pole is provided that has a first end and a second end; with a socket positioned at the first end. Finally, the first end of the pole is positioned within the annular hole such the central core of rock is received in the socket at the first end of the pole to provide additional stability to the pole.

Abstract: A two component chemically thermoset composite resin matrix for use in composite manufacturing processes includes a solvent free polyisocyanate component and a solvent free polyol component. The solvent free polyisocyanate component is either an aromatic polyisocyanate, an aliphatic polyiscyanate or a blend of both. The solvent free polyol component is either a polyether polyol, a polyester polyol or a blend of both. The polyisocyanate component and the polyol component are in relative proportions in accordance with an OH/NCO equivalent ratio of 1:1 to 1:2. The components form a relatively low cost polyurethane composite resin having a useful range of physical properties, without the emission of volatile organic compounds during curing.
