CONSTRUCTION A NEW STANDARD FOR SPEED AND STRENGTH IN CONCRETE EXPANSION JOINTS
The unique properties of Gilsonite make it an integral part of the production of asphalt-impregnated fiberboard, known as concrete expansion joints.
Asphalt-impregnated fiberboard made with Iranian Gilsonite has the industry’s highest asphalt content, so it always meets the ASTM Standard. For concrete expansion joints, we provide a special grade of Gilsonite that is sized so no additional grinding is required for introduction to a slurry tank. That means higher quality, streamlined processes and better project integrity.
The unique properties of Gilsonite also enable faster production. Because Gilsonite is naturally hydrophobic, it speeds the release of water as the mat is formed. When the board has been heat pressed, Gilsonite’s adhesive properties bind the fibers together, making a stronger board.
