Abstract

A device for damming and diverting liquid on a spill surface has an elongated, pliable dike having a first end, a second end and an exposed surface. The exposed surface is inherently tacky so that it is adherable to the spill surface to prevent flow of liquid past the dike. The dike is preferably made from a substance, such as polyurethane, that is inherently tacky. The device provides improved tear resistance by one or more additions to the construction of the device. Some of the additions to the construction also improve UV resistance and/or chemical compatibility. A method for creating a liquid control zone on a spill surface utilizing the dike of the present invention is also disclosed.

Claims

exact text as granted — not AI-modified

         13 . The device of  claim 1 , wherein the protective layer comprises natural rubber, synthetic rubber, EPDM rubber, nitrile rubber, thermoplastic olefin, polyvinyl chloride and/or chlorosulfonated polyethylene. 
     
     
         14 . The device of  claim 1 , wherein the protective layer comprises rubber. 
     
     
         15 . A device for damming and diverting a liquid on a spill surface, comprising:
 an elongated, pliable dike made from an inherently tacky, resilient material, the elongated pliable dike having a side and an exposed surface adjacent the side; and   a durable covering adhered to the side of the elongated, pliable dike;
 wherein the exposed surface is adherable to the spill surface to prevent flow of the liquid past the dike. 
   
     
     
         16 . The device of  claim 15 , wherein the durable covering includes a low density bonding layer and a protective layer. 
     
     
         17 . The device of  claim 16 , wherein said exposed surface is substantially smooth. 
     
     
         18 . The device of  claim 16 , including a tacky abutment surface on each end of said dike. 
     
     
         19 . The device of  claim 16 , wherein the low-density bonding layer has a thickness of at least 0.01 inch.
