In 1960 The D.S. Brown Company began designing and extruding the first generation of Delastic® Preformed Compression Seals. To withstand the demanding requirements of bridge/highway installations, all Delastic® Preformed Compression Seals are extruded from neoprene (polycholoroprene) compounds which satisfy the ASTM standard specification D3542 for Preformed Polychloroprene Elastic Joint Seals for Bridges.
In addition to highway and bridge applications, Delastic® Neoprene Compression Seals have also been used in spillways, dams, parking structures, stadium ramps and pedestrian overpasses.
Other Seals
Delastic® CS & AF preformed seals provide a level top surface that is particularly suited for pedestrian traffic. Once in the compressed state, the top sections are much closer together and form a level walking surface and a pleasing visual effect for exposed vertical applications.
