Abstract (en)

[origin: WO9850640A1] A method of increasing the structural strength of a load bearing member such as a pile (12), particularly for the purpose of reparing a damaged pile, includes the steps of securing a rigid, structural sleeve (17) around the pile (12) and spaced therefrom to form an interspace (18), filling the interspace (18) with an expansive filler (19), and allowing the filler (19) to set and expand in the interspace (18) to impose tensile hoop stresses in the sleeve (17) and corresponding compressive hoop stresses in the pile (12) to enhance the load transfer between the pile (12) and the sleeve (17).
