I am about to revamp a small courtyard are there any "green" paving slabs ...or other materials /

Try looking in your local business telephone book. There should be a local "Reclamation Yard" where you can ring and enquire. We have a local one in Norwich. Or you could try the local "freecycle" (Yahoo!) where peeps want to get rid of their stuff. You can also advertise a "wanted" on the sites.

no but at greencrete they sell concrete stain in all colours

There are green agregates 20mm size, on a membrane you will hold moisture in the area.

nice one doc again you come good mate.that sun is lovley

You mean green as in environmentally friendly, not green colour, right?

You can ask on freecycle in your area for slabs, people are always changing their gardens. I believe you can get slabs made of recycled concrete too, but not sure where.

erm oops lol

Haha NP, i thought the colour green Too, :)))

great minds think alike lol

Oh I don't know now! Lol! Now it's prob. me with egg on my face folks! Lol! Never thought of the colour green, hehe!

Most agregates are "green". Used with a membrane it promotes a green environment.

cool lol
