Thanks for your question about the cost per sq. ft. of our poured-in-place rubber surfacing. The price is determined by the location and size of the playground area. You may contact a No Fault Representative at 866-637-7678 (toll free) for more information. Or, if you send me an e-mail at carmen@nofault.com with your contact info., I'll be happy to forward it to the appropriate sales person and have them contact you directly. Thanks so much!
