I would really appreciate some advice. I had a landscaper in to install artificial grass, however its been 5 weeks now and I still dont have a lawn, the frame is uneven and too high I asked for grano dust instead of sand as I have a dog. however he has since put grit sand in and insisted it is grano dust. anyhow it will be rectified by someone else. but does anyone have artificial down without a membrane ? as he hasn't laid one ontop or under the MOT ?
