I've got an 8' retaining wall, runs about 120' across the back of my property (faces my house). It's railroad ties and has about run its life.
I'm looking to replace with some kind of stone/block wall. Had contractors out for bids on using engineered block.
But I'm also wondering about what's called "Boulder walls". Basically, just stacking (with skill) large 1000+lb boulders in place, after digging out the ties, then backfilling with gravel, plus using a french drain along the top to drain off excess.
Is this something that's not advisable in this area, or would it be ridiculously expensive vs using block, so no one does it?
