Plenty thick to hold up to driving on with a loaded dump truck over a thin layer without ripping. Does exactly what it is supposed to do and does it well. Shipping was fast too.
Goes down easy. Cuts easy with scissors. Tough, but water permeable. I had one spot get a small amount of damage when a fully loaded dump truck drove over it while turning the front tires.
I measured the dimensions and they are as advertised. Pretty easy to install. I cannot vouch for its durability as I just installed it. That is why only 4 stars. Looks pretty decent though.
