RAB Asphaltic Deck Expanion and Contraction Strips are formulated so as to absorb the likely seasonal movements found in large unrestricted areas of mastic asphalt such as roofs, car decks, pavings and floorings.
These expansion contraction strips, being flush finished to the surfaces, are suitable for traffic and pedestrian areas. However they are not to be classed as an expansion joint. If in doubt please seek our technical advice for alternate system.
