Hi All,
Kindly provide some advice on how to fix a door hinge as the cement from the wall has come out (please refer photos). I was advised by a building inspector to redesign the gate by getting some steel plates attached to the wall and then hooking the gate to it so that the weight of the gate in not on the corners of the wall.
Quite novice at this so apologies if some of the terminology used is not correct.
Thanks in advance!
