Expansion joint strips should be made as butt connection with careful placing of the expansion joint membrane by sliding the protruding membrane from the top strip onto the membrane on the bottom strip from the top with overlap – in order to ensure that precipitation water will not penetrate under the strips when flowing down the membrane.
