CA 2036748
A seal, constituted by a water-expansible portion and a water-unexpansible portion, prevents water from leaking in a construction joint. The expansible portion surrounds the unexpansible portion everywhere except on a side of the unexpansible portion which is adhered to one of two mutually facing surfaces of the construction joint. The unexpansible portion is sized, relative to the overall size of the seal, particularly in the width dimension, so that it adheres with sufficient strength to one of the mutually facing surfaces of the construc- tion joint so as not to become pulled off in use. An effective seal thus is maintained even in a swollen state.
