Steel and Rectangular Columns

Rectangular steel and concrete columns can be sealed by using a combination of external and internal pre-formed corners, extended with radon barrier if required. These all need to be overlapped and sealed using our adhesive Butyl Tape

We have also designed single strip that can be used for H-shaped Steel Columns. Simply paint on a bitumen  adhesive to the steel column and slide on our H-Column jointing strip. Please click on the PDF link for more instructions.
