ABSTRACT:
A structural element at least partially defining a void space is strengthened and stabilized by filling the void space with a structural foaming agent. The predetermined quantity of structural foaming agent used is such that it has the capacity to foam and expand, when unconfined, to a volume substantially greater than the volume of the void space. Bubbles created during the foaming of the structural foaming agent burst at the interface between deteriorated wood surrounding the void space to create a pulsing action which promotes impregnation of the deteriorated wood by the structural foaming agent.
