To provide a robust paved surface for both car parking and pedestrian use which could allow all surface water, both from the car park and the crèche roof, to infiltrate back to ground.
The client wanted a fully designed and guaranteed permeable paving system which would allow full infiltration to ground and therefore remove the need for surface water discharge to combined sewage pipe.
The products would have to:
Accommodate the vision specified by the architect
Be sympathetic to the modern design of the main building
Be available to suit the ambitious project timeline
Produce a safe surface, free of standing water, which can stay looking good for years
