I drilled it into concrete but it pulled out in the first wind stormBought thinking a use it as a barrier for small dogs. Once setup, even with maxium tension, I realized at posts at 6 ft apart (like recommended) a strong breeze would wear away at the fabric connections. I moved them to 4ft apart but now was short on posts for the entire 24 ft length of fence. I bagged it up and returned asap. I don't know why this product is called a fence. A strong wind will loosen the fabric and eventually take it down even if installed to spec. Don't buy. Its not a sturdy reliable barrier. And what can call privacy when its only 4ft tall? Save your money, not worth it.
