  • Installation options including hot bonding.
  • Contains no pitch or plasticisers.


Visqueen Zedex Bitumen DPC can be used horizontally at door and window jambs, over lintels, vertically bonded to the cavity face of the inner leaf to facilitate requirements for level access and wherever a flexible and adaptable damp proof course and cavity tray system is required.
