Drainjoint

Application

  • For residential and commercial applications.
  • For use on standard permeable sub-base with sand joints as per Interpave and BS EN standards.
  • Suitable for paved areas with pedestrian and vehicular traffic.

Description

Drainjoint allows for any material to be laid as a permeable paving system, be it natural stone, clay or concrete, and it can accommodate any paving size (not just those designed for a 6 mm aggregate joint). No aggregate joints mean no continuous maintenance or rattling of blocks. No rattling reduces the potential for surface failure and eradicates the need for expensive re-jointing. Paving can be cleaned with a standard mechanical sweeper and, as Drainjoint is non-degradable and does not absorb water, there is no potential for freeze-thaw damage.


Features and benefits:

  • Custom-made to suit the size of the blocks.
  • Does not require additional surface drainage.
  • DEFRA compliant design service.
  • Paving can be laid to 'no falls'.
  • Sustainable, cost-effective and easy to install.
