ABSTRACT:
A tubular member is arranged to be inserted in a hole drilled in adjacent monoliths astraddle a joint between the monoliths. A tubular member comprises an outer layer of material saturated with a resin capable of bonding to defining walls of the hole. An inner layer of fluid impermeable material is bonded to the outer layer of tubular member. Prior to installation, the tubular member is non-inverted, having the resin saturated layer on the inside whereby upon being inverted into the hole by an inverting gas or fluid, the resin saturated layer turns outwardly for bonding to the walls of the hole. A core portion is placed in the tube to hold it in tight bonded engagement with the hole, such core portion comprising a grout having an elasticity which when cured flexes with differential movements of adjacent monoliths.
