Our backyard retaining wall is deteriorating and needs to be replaced. It=92s 4=92 high and about 30=92 long. We believe it=92s stone (with mortar) covered by a layer of concrete. Most of the wall is outside, but a section of the wall supports a furnace room. (The furnace room is connected to the house, but there=92s no access to the furnace room from inside the house). Some contractors have recommended installing a poured concrete wall. Some contractors have recommended installing 10=94 CMU blocks filled with concrete and rebar. Some contractors have recommended replacing only the exterior portion of the wall with modular block (Versa-Lok, Mesa Wall, Unilock, etc.) and using rebar to tie into the existing section in the furnace room. What=92s the best solution? We=92re in New York state, so freezing in the Winter is an issue. Thanks very much!
