Double Sided Butyl Tapeis made of a super tacky butyl rubber that sticks well to most masonry surfaces and also polyethylene. Being a two sided tape, this will allow you to mount materials on vertical surfaces and will also create a seal. In some situations it can be used as an alternative to using nails and washers or screws to mechanically fasten the polyethylene liner or rigid foam insulation. At the same time, it can serve the purpose of sealing the liner or insulation board to the wall and eliminating the need for caulking.
