  • Method for repairing a pipe coupling
    Patent number: 4358417
    Abstract: Method of repairing a leaking bell and spigot joint employing a containment which is fit around the coupling to form a completely enclosed annular cavity. A premixed fluid composition comprising an acrylic, a resin, a filler, and a blowing agent is injected into the cavity. This hardens exothermically, providing heat to activate the blowing agent and expand the composition as it sets, forcing the composition into any irregularities to seal the leak and leave a pressurized acrylic sealing ring on the pipe.
