Lock-Block Retaining Walls
Lock-Block Retaining Walls
(OP)
During an excavation for foundations, lock blocks were placed to support the neighboring excavated profile. The total height of lock blocks is about 3.5 m. (5 rows). The blocks were positioned on top of each other with no reinforcement by a contractor. The gap between the lock block and the sloping ground has not been back filled except partially.
I am looking for a methodology to reinforce the existing lock-blocks to provide additional lateral support for the blocks without being have to remove the lock blocks. Thank you.

Apparently the "wall" is not holding back much other than lower backfilled area. Seems like a cheaper way would be to remove blocks down as far as possible and then install soil nails by hand held drills. Not the best alternative, short of cantlevered sheet piles.
If there is some serious risk of losing the adjacent land, I'd fill the hole and start over doing it right.
