- The project size was approximately 15,000 linear feet of new construction joints
- Installation temperature was below 0° F.
- Material specified: ES-2350 SubZero a hybrid, 1:1 ratio polyurea specifically developed for concrete crack and control joint sealing on indoor, cold storage, warehouse facilities.
- Material, cures in approximately one hour from time of installation and develops a shore A hardness of 92-95.
- While the product can be hand mixed, on all large projects manufacture recommends that the material be installed using a heated, plural component pump system such as the “Condor” Sub-Zero, manufactured by Elastomer Specialties, Inc.
- This project located in Enid, Oklahoma was completed in the fall of 2002, and took approximately 3-4 weeks to complete.
- The contractor, Gleason Contractors out of North Dakota was responsible for the new facility construction as well as the joint filling.
- Installation procedure was the same as all new construction joint sealing.
