replacing retaing wall need advice
I have included a link to a picture of my current retaining wall that needs to be replaced.
I have had 3 different companies tell me they would do it 3 different ways. All 3 have suggested a 95 pound landscaping rock like I see on other walls around town. They recommend different types of material to put under it and how far below the surface the first footing row should be. Some say a base of peat rock, some say broken concrete. Some say geogrid is needing others say no. Some say use mason's adhesive between the rocks, others say not necessary.
I will check all 3 out with the Better Business Bureau.
Any advice anyone can give me from the footings on up as well as the type of blocks to use would be appreciated. There is a gutter that will have PVC or something like it running underground out the full 30 feet to get water away from the foundation.
The current wall is about 36 feet long and starts at about 7' high, at the highest point, 10 feet down the wall it is at 5 foot high.
Any advice anyone can give me on what the best retaining wall should be would be appreciated. I want a level wall that will last a long time. If there is another site that would be more appropriate for this type of post I am ope to suggestions. Thanks Dorothy
