Thick strong product.
Excellent product. Put it down on large area I had cleared ready to put artificial grass. Had to leave it for several months and did nt want weeds etc growing back. Worked perfectly when I came back to it in 5 months it was perfectly clear as I left it. Very thick strong material at a great price. Excellent!
