http://www.celltekdirect.com/solutions.asp I see there are some older threads about this stuff here. But nothing for about the last 9-12 months. So has anyone had a chance to install this stuff last year? And what do you think? What are the main advantages of using this product? Does it decrease labor in any way or mean that you don't need as much aggregate? Also, what are the applications? Would you use this for every pathway and patio you installed? Or just the larger stuff like Large Patios, Driveways and Plazas?
