  • A. The expansion joint material shall be furnished in one continuous piece for each joint, wherever possible. If field splicing is required, the material shall be heat spliced in accordance with the manufacturer's recommendations.

    B. Apply approximately 6 mils of the epoxy bonder to the vertical interface of the (epoxy mortar nosing) (concrete substrate) and the sides of the expansion joint material. Tape shall be place on the top of the (epoxy mortar nosing ) (adjacent concrete surfaces) to prevent spreading of epoxy bonder on same. Remove tape prior to the curing of the epoxy bonder.

    C. Compress and install the expansion joint material. Remove excess epoxy bonder from the top surface of the joint material prior to the curing of same.

    D. Final position of the joint material shall be (1/8"below) (flush with) ( ) the adjacent horizontal surfaces.

PART 4 METHOD OF PAYMENT

4.01 The expansion joint system shall be paid for by the lineal foot of joint installed, including all necessary materials, labor and equipment required to prepare the joint opening (install the epoxy mortar NOSINGS) and install the expansion joint material.
