I need to anchor a chainlink and tubular metal framed dog pen to concrete flagging. The flags are 5cm deep, with a 5cm subbase of dry-mixed sand/cement. Not yet laid, but I need to do this REAL soon now.What's the best approach to anchoring these laid-flat metal tubes to the flagging, without having to compromise the flagging too much, or install the anchors from the underside before laying the flagging)?I guess the ideal would be something like a u-bolt bracket that hammers in like a standard anchor bolt.Is there anything like that, or what would you suggest? via /r/DIY http://ift.tt/2xroffX
