A rig for lining with brick a kiln, tunnel or like surface embodies a frame that is of variable size to suit different surface diameters, and two relatively adjustable jacks support deformable arcuate brick column support members at each opposite sides of the frame. Each arcuate member is a continuous longitudinally deformable trough containing an expansible tube overlaid by a solid rubber or like flexible brick contact element.
