Butyl tape is a self adhesive pre-formed peel and stick material. When changes need to be made to the layout of your retaining wall, butyl tape is the recommended alternative to Bond Loc. Prior to use, sweep top of units. Then simply apply the ribbon of tape to the area which is to be secured to, press firmly along the entire length of the release paper backing, cut the tape to length, and remove the release paper.
Rule of thumb - one 6 metre (20 feet) role can secure 3 metres (10 feet) of capping, assuming a double bead is used.
