Abstract
A sealing tape for concrete forms has a foam layer to fill spaces between parts of the form, and pressure sensitive adhesive for adhering to the form. The side of the sealing tape to be fixed to the base plate of the form is a fabric reinforced tape with sufficient integrity that the sealing tape can be entirely removed from the base plate by merely pulling up the reinforced tape. For some forms, the sealing tape may have an adhesive on both sides, and for other forms, only the side having the reinforced tape may have adhesive thereon.
