摘要:
A method for reinforcing in-place a hollow wooden structural component (1), in particular a damaged utility pole, by injecting into the internal cavities of the structural component (1) a polyurethane composition (2) which forms, upon curing, a rigid polyurethane (2) having a density of at least 40 lbs./ft.3 and a flexural strength of at least 3,000 psi. The polyurethane composition (2) is produced in situ by continuously metering and blending an isocyanate-containing liquid component and a polyol-containing liquid component.
