Hi I have a retaining wall, in some places over six feet high and fifty feet long, made from breeze blocks. It's been there since I bought the house (over forty years ago) but there are cracks appearing in it and there's a definite but slight outer lean developed. It needs rebuilding. That's not something in my skill-set and I can't afford a builder at the moment. It's probably getting dangerous and I do think I could take it down block by block - maybe to half height. Is it worth while keeping and cleaning up the blocks to save a bit of money on the rebuild or is that not worth the effort? I've no idea how much these blocks cost. Thanks in anticipation.
