More and more airports are using Penatron 3003 because it does not damage the existing concrete pavement and very little time is needed to install lights or fill conduits. The J246 is a unique polyurea product that has greater density and toughness than standard silicones and urethanes. J246 has the ability to flex quickly, and does not loose its flexibility in cold temperatures and its resilience makes it ideal for bridge decks, slab expansion joints, airfield expansion joints, and even parking structures. Parking Structure Expansion Joints J246 is a perfect solution where a soft flexible material is needed, such as parking structure expansion joints. J246 can bridge a large moving joint and be installed along with Penatron 3003 as a header nosing.
Traffic can resume in as little an hour after the application is completed.
Not Brittle Available in Various Durometers Airfield Expansion Joints J246 is also installed with a plural component pump for rapid replacement of damaged airfield expansion joint sections. The joint area is first cleaned to remove all dust. A dry diamond blade is used to remove concrete contaminated with damaged silicone product to produce a clean, rough profile for the J246. A backer rod is added to the bottom of the expansion joint area to limit the depth of the fill. The pump applies the self-leveling J246 and the area is returned to service in about 45 minutes.
