Aquaflow Permeable Paving (SuDS)

Multi Colour Bloch Paving Golden Brindle Block Paving Multi Colour Bloch Paving

Product Overview

You will notice that the Aquaflow paving blocks have small channels around the block. It is these channels that allow water to drain though the surface of the paving into a specially designed sub-base. This sub-base consists of particular components that each perform a different task.
 
1. Laying Course – 2-6mm crushed stone, a 50mm screeded layer.
2. Inbitex – a green fiber geotextile to filter and clean rainwater.
3. Sub-base -5-20mm crushed stone, the load bearing layer
4. S.C. Intergrid- a square grid that aids the sub-base loading capacity.
5. S.C. Membrane – An impermeable black plastic liner to create a watertight tank.
6. Aquaflow surface dressing – a 2-4mm grit that is brushed into the joints. 
 
All of the stone within the construction must be clean, crushed and angular. The angular shape of the stones create a honeycomb like structure. This allows water to drain into and become stored within the sub-base. The surface therefore needs to be protected from fine material such as soil and sand. So for example if you have a delivery of turf or top soil you must ensure that you cover the driveway to prevent spillages that could affect the draining capabilities of the surface.
 
The Aquaflow area should be swept regularly to keep it free of leaves and other debris.
 
The system will deal with small quantities of oil spillages, but any vehicle maintenance such as an oil change, should be carried out away from the Aquaflow area as a precautionary measure.
