Thank you guys.
I will have a look for mastic. The wall shouldn't drop anymore as I've sorted the cause but I guess it's a good idea to setup a check in case it subsides any more.

Looks like subsidence to me too. First thing is to check if it is still moving. You could get a 25x150mm length of glass and fix it with epoxy resin so that it spans the joint. Give it a few months to see if the glass breaks, if so it is still moving and you need to fix it, possibly by knocking the wall down and putting new footings in. If it isn't moving you could fill the gap with a non setting mastic like Sikaflex EBT.

That looks like subsidence, eg the whole wall has sunk.

You could pack it with the expansion strips as existing and then face it with mastic

Wall gap
Dec 8th, 2017, 11:48am
 


Hi there,
sorry I don't know how to rotate the image.

I have this gap appearing between two walls in the garden. I know it's down to some heavy gates pulling the wall to one side, but that is fixed now. I just need some advice on filling the gap. Do I need to remove the sealant or whatever it is, and if so how. And then what shall I use to fill it.

Many thanks
