Drainjoint permeable paving is easy to install and can be used with many different materials. Removing the need for pavers to carry nibs or extensions and avoiding the requirement for large, unsightly aggregate joints, the system preserves the beauty of the paving material.
With the ever-increasing urbanisation of the countryside and changes in rainfall patterns it has led to much higher volumes of surface water entering sewerage systems and water courses. This, in turn, has resulted in higher instances of flooding in city centres, greater expenditure on new sewerage systems and insurance companies increasing premiums on properties built in vulnerable areas.
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 6mm aggregate joint). The product is designed to be sustainable, cost-effective and easy to install.
No aggregate joints means 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.
