Hi, I have been asked by a primary school to realise a garden designed by the children, approx 20m x 10m, with 9 raised beds. They need wheelchair access therefore a hard surface required and budget not huge (I have looked at recycled plastic wood like Milboard for another project but it's probably too pricey).
Any suggestions for tried and tested, hard wearing sustainable / low impact/recyclable landscaping materials? The garden area is currently a playing field so pretty level.. thanks
I have very successfully used the gravel stabilisation system manufactured by CED Aggregates in Thurrock Essex in gardens for both elderly and younger wheelchair users and as a car park surface. Not only is it stable it's free draining so no planning (should there have been a need) required. Their website is http://www.ced.ltd.uk/Cedagravel/.
Should you require any further help, I have designed and built quite a few gardens for vulnerable, disabled (both mentally impaired and physically) people in an institutional scenario. Feel free to ask.
Another alternative could be gravel-filled plastic honeycomb tiles (e.g. ECO-GRID), which could be laid on sharp sand over geotextile directly onto the compacted ground. This would be free draining, the grid tiles are made from recycled plastic, and the gravel is recyclable - or another recycled material (e.g. crushed glass) could be used if there's a local supplier and the costs look good. This would work best if the designed surfaces are rectilinear - tiles can be cut to shape, but it would be tedious, increase labour costs and might need extra edging restraints.
