Jointing tape
For sealing lapped joints in the DPC or for sealing the DPC on to the accessories.

Joint supports
For fitting below lapped joints in the DPC to provide support and allow the jointing tape to be sealed correctly.

  • As with the DPC, accessories should always be bedded on to fresh mortar, never dry bedded. The masonry laid over the DPC should also be bedded on to fresh mortar so that the DPC is approximately halfway through the thickness of the mortar joint.
  • DPC must be lapped on to the accessory by a minimum of 100mm.
  • All lapped joints must be fully sealed with jointing tape. It is essential that the jointing surfaces are clean and dry or the jointing tape will not seal correctly.
  • State the wall construction, cavity width and the rise which is required across the cavity.
  • If you need a special, tailor-made accessory – please supply a dimensioned sketch detailing your requirements.
