Some embodiments comprise an integrated reinforcing crossmember having a carrier with an expansible material adhered to at least a portion of the exterior surface of the carrier. The carrier is comprised of a center section and two end sections, each section comprised of external lateral walls and internal ribs joined by cross walls and horizontal connecting walls. The crossmember is inserted into a cavity of a corresponding structural member, and the expansible material is activated and expands, securing the crossmember in place within the cavity.
