Abstract
A hollow working pole such as a luminaire pole is repaired by cutting the pole above ground level and inserting a sleeve. The sleeve is maintained in position while grout is poured to fill the space between the sleeve and the inner surfaces of the pole base. The top portion of the pole, previously removed, are replaced and grout is poured into the circumferential space between the insert and the inner surfaces of the upper portion of the pole.
