Abstract: A method for reinforcing in-place a hollow wooden structural component, in particular a damaged utility pole, by injecting into the internal cavities of the structural component a polyurethane composition which forms, upon curing, a rigid polyurethane having a density of at least 40 lbs/ft.sup.3 and a flexural strength of at least 3,000 psi. The polyurethane composition is produced in situ by continuously metering and blending an isocyanate-containing liquid component and a polyol-containing liquid component.
