<p>A tubular member is arranged to be inserted in a hole drilled in adjacent monoliths astraddle a joint between the monoliths. The 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 the tubular member. When installed in a drilled hole, the tube is placed with the resin saturated layer against and in bonding relation with the wall of the hole. A core portion may be placed in the tube to hold it in tight bonded engagement with the hole, such core portion comprising a flexible filler such as grout having an elasticity which when cured flexes with differential movements of adjacent monoliths. The tubular member has two or more barriers therein which prevent the saturating resin from washing away during installation.</p> |
