Cracking in double tee flanges is occasionally encountered on newly erected parking garages. This is commonly the result of torsional stresses developed during loading, transporting or erection of the member. Similarly, this may occur when a double tee is "warped" in its final position to allow for proper drainage. This type of cracking does not jeopardize the structural integrity of the double tee. To avoid long-term durability problems, these cracks should be filled with an approved sealant or epoxy. Epoxy repairs should be covered with a cementitious material to limit UV exposure.
