Joints are sealed by applying a mixture of a resin and a water-swellable filler, and allowing water to contact the applied mixture. The mixture which is storage stable and can be sealed in a one-pack container, can be provided in admixture with a volatile organic solvent which may need to be allowed to dry off before allowing contact with water. Alternatively, the mixture can be applied hot, the resin being thermoplastic, either directly to the or each member of the joint or to an impregnatable matrix which is subsequently applied. |
