Claim:
A reinforcement system, comprising: a structural member having a first cavity with a longitudinal axis, a second cavity with a second longitudinal axis, the first and second longitudinal axes being substantially parallel and the first and the second cavities being separated by a barrier with an opening therein, the opening joining the first and the second cavities; a reinforcement component being insertable into the structural member through the opening, the reinforcement component having: a first portion shaped to fit in the first cavity having a longitudinal axis; a second portion shaped to fit in the second cavity, such that the second portion has a longitudinal axis that is substantially parallel to the longitudinal axis of the first portion; wherein, the first portion and the second portion are connected at a region that is insertable through the opening such that the first cavity and the second cavity become substantially separate and the opening becomes substantially closed upon insertion of the reinforcement component; wherein, expansible reinforcement material is disposed on a section of at least one of the first portion or the second portion; and wherein, upon exposure to heat, expansible reinforcement material is adherable to the structural member in at least the first cavity or the second cavity.
