Hi all,
Our garden wall is a fairly high wall made of flint-ey rubble and what looks like very crumbly lime mortar. It has been damaged by vegetation (I'm currently extracting massive bits of ivy from parts of it) but this is what it looks like underneath. What would be the best way to fix this, given the underlying mortar is crumbly? Just put new lime render on and push in the stones that have fallen out? Thanks for any insights!
