Dwarf garden wall is about 1 foot high and comprises bricks of approx 12"x5"x4". Mortar is cracked and now some bricks sit prouder than others. Believe this might possibly be due to root damage as the wall is a boundary wall with our garden with its many shrubs/trees on one side and the public pavement on the other. I think ground is a similar level either side of the wall. Ground is clay.
Is it possible to stabilise rather than re-build, assuming this is a quicker and cheaper option?
Thanks, J Parsons
