Rocky Mountain Goods 4 Mil Black Plastic Sheeting - Roll of Heavy Duty Thick Plastic for Gardening, Weeds, Yard, Landscaping, Barrier, Under House - Multi Use Polyethylene

Just what I ordered

Bueno y resistente, pero no es de 4 mil, tiene el mismo grosor de una bolsa de platico jumbo.

It was very thin and expensive. I found I could buy a roll from Bunnings that was double the size, double the thickness yet just over half the price. A total waste of time and money. Very disappointed.

We are using this for both weed control and killing off undesirable plants in prospective garden space but also as a weed barrier for our growing garden plants. It is thick and tough, does not tear easily, and is easy to work with if you keep it secured to the ground well. Otherwise it will turn into a sail and fly off if the wind picks up. Very pleased with this product.

Great for under mulch or pebbles. Used to cover small patio before adding mulch. Way better than the mesh-like ground cover.
