An epoxy grout suitable for use in mounting and positioning bearing runner plates used in hydrostatic bearing assemblies for rotatably mounting large radio telescope structures to stationary support pedestals. The epoxy grout may be used in original mountings or may be used as part of a replacement system for repairing cavities in existing grout resulting from grout deterioration. The epoxy grout has a relatively short work life and cure time even in the presence of hydraulic oil. The epoxy grout cures without shrinking or sagging to form a grout which is sufficiently strong and durable to provide a grout especially well-suited for use under the high pressure loading and close tolerance requirements of large hydrostatic bearing assemblies.
A fast-curing, non-sagging, oil-compatible, support grout consisting essentially of between 10-20% by weight of epoxy resin;
