Watertight joint and method of sealing drainage and sanitary sewer pipe sections

摘要

A seal and method for forming an in-field watertight seal between rigid pipe sections such as concrete pipe sections by applying on the periphery of a pipe section a continuous bead of a non-sagging gel formed from a curable mixture of low viscosity components. A second pipe section is positioned to form a joint with the first pipe section wherein the gap between mating surfaces of the two pipe sections is filled with the mixture which forms a flexible polymeric elastomer seal upon curing. Physical properties of the components and the seal mixture are disclosed.
