If you want to cover the blocks, attach vertical furring strips to the block and install 5/4" x6" wood on the furring strips. Cap it with wood or stone. It covers the wood, doesn't compromise the cinderblock structure and nothing goes to the landfill.
Existing cinder block wall is still true.
Cinder block wall is 5'x50'. Wall was installed 40 ago and is still true shows no sign of movement.. Can I lay rail road ties on the face and how can I attach them to the cinder blocks. I can't see removing blocks since wall is still shows no sign of movement and not removing blocks would be 1 less thing going to landfill.
