Repair to small brick wall - what type of 'cement' do I need? [pics included]

clueless78

I have a small brick wall in my garden, there used to be a large tree just behind the wall and it looks like it's roots have caused the wall to crack.

I'd like to repair it to make it a bit more stable and was hoping for suggestions on the best type of concrete/mortar mix for an exterior wall. Any other tips gratefully received

Ordinary portland cement, or possibly sulphate resistant cement.

Were you thinking of rebuilding that section, or just repointing it?

I was going to try and pull the triangle of bricks out as one piece and cement back in - I'm sure the non-bodge way would be to knock each brick off separately and put back but I'm looking for the quick fix!

That will work as long as you can clean off the mortar without fracturing any of the joints. When you it in butter up the cross joints on the existing wall as well as the ones on the piece going in. You could damp down the area a bit as well for a better bond.

Thanks, when you say 'butter up the cross joints' do you mean spread the mortar on the existing wall surfaces as well as on all the edges of the piece I'm trying to fit back in?

Yes that's correct. When you lay the last brick in the line for example, the closer brick as it's known, should have both ends buttered up and the ends of the bricks where it's going should be buttered up as well. This just makes a better joint.
