Asphalt impregnated fiber expansion joint

SpecFlex is manufactured through a proprietary process that allows individual fibers to be saturated in the asphalt preservative before they are processed into final mat form. As a result, SpecFlex gives superior asphalt distribution, product strength, flexibility and long term aging characteristics. It is a high quality, competitively priced alternative to conventionally produced fiber expansion joint materials.
