The problem with this gate was it is extremely wide (over 3 metres) and when originally installed, the footings were never dug deep enough to support the weight of the large gate so after a period of time the gate started dropping off thus not closing or opening properly.
The remedy was to chop out the existing footing, dig down deeper, give the gate adjustments and pour 55mpa concrete which means this gate isn’t going anywhere!
