A clamp arrangement for sealing a lap joint includes first and second reinforcing bars and a ductile band with first and second end portions wrapped around first and second reinforcing bars. A gasket member is positioned between the first and second reinforcing bars. The gasket member includes a deformation opening for allowing the gasket member to conform to a step in a lap joint. The gasket member is constructed and arranged to maintain the first and second reinforcing bars in parallel alignment, when the clamp arrangement is tightened around the step of the lap joint. Methods using these clamp arrangements are provided herein.
