A method for fastening rock bolts in geological strata and a two-compartment package containing expansible resinous composition including unsaturated polyester resin syrup, aluminum chlorohydroxide and activator for the resin syrup. The method introduces an expansible composition into an opening in the geological strata, and foams the composition in engagement with a rock bolt. The preferred method introduces a two-compartment package of the composition into the opening in the geological strata, ruptures the package with the rock bolt, and mixes the composition by mechanical motion of the rock bolt.
