Hanson Formpave 'Aquaflow' block
Permeable paving for use on car parks, drives and moderately trafficked areas
'Formpave have designed a range of Aquaflow paving blocks to be used in conjunction with either tanked or infiltration systems.
The range is manufactured from concrete with a tensile splitting strength in accordance with BS EN 1338:2003.
All of the blocks and slabs provide drainage through vertical channels and will allow water through the surface at a rate of approximately 9000mm per hour (9000 litres per m2 per hour). The Inbitex geotextile beneath the laying course will allow approximately 4500 litres per m2 per hour through and this figure should be used for design purposes.
Size: 100 x 200 x 60/80mm
Laying pattern: Must be laid in 90o herringbone
Colours: Natural, Burnt Red, Red brindle, Golden brindle and Charcoal.
