Abstract: Method for increasing the distance between two faces, inserting into a space between the two faces a diaphragm power jack, the shape of which being adapted to the shape of the space, the diaphragm power jack comprising two abutting sheets being sealingly bonded along the entire circumference, a pipe penetrating the bonded, injecting a pressurized fluid through the pipe to the interface between the two sheets thereby forcing the sheets apart whereby substantially all the energy from the pressurized fluid being converted to forces perpendicularly to the sheets.
