Fibre Expansion Joint is a composite blend of cellulose long strand fibers in an asphaltic binder securely bonded together and formed into a semi-rigid board. This environmentally safe compressible material is economical while being stronger and easier to handle than other joint filler compounds. Because of its long-term aging characteristics, RIGHT-JOINT is ideal as a filler strip in expansion control joints for most types of concrete construction. This material meets or exceeds all specifications, resists breakage, cuts cleanly, and is easily held in position during concrete pouring. It recovers a minimum of 70% of it’s original thickness after compression as well as resists water infiltration and withstands freeze/thaw cycles.
