I agree. The right way in my opinion would be to put a retaining wall in with drain tile above like you mentioned. In addition, I would backfill the retaining wall with clear stone and install drain tile directly behind the wall at the top of the footing. The wall should be high enough however, so that you don't have to change the grade down to it by very much. I would suggest the wall to be at least a 10" wall, 4000 psi, with piers, on a 10" deep x 30" wide footing, and follow the footing around the piers, with plenty of re-bar both vertically and horizontally in the wall.Originally Posted by td25c
Welcome to the forum supt.Your plan sounds good.I forgot to mention to thebig450es about installing gabion wire baskets as a retaining wall.We use them in waterways & ditchbanks.They seem to work pretty good.They dont need any drainage behind them as they are filled with "rip-rap",ground water just flows through them.They hold back the ground good.
I like the idea of using the baskets, where is a good place to get them and what type of fill do you reccommend.
www.gabionbaskets.net
that just a site I googled...
I've worked around them .... They had a machine with hog rings that put them together... then laborers stacking them .... and more hog rigs...
We used 5 x 9 rock... at least I think that's the size.... they would set a basket then fill it with a hopper then hand place a few rocks. then staple the top
they use them a lot . but they usually end up just being weed planters
and appear to hold up well
I thought about it the other day after viewing your pictures of the your friends job.Looks like it could be tough getting concrete up behind the home.I was calling the baskets in the pics I posted "Gabions" but they are another brand ,very similiar.I'l remember the name after I log off tonight.They measure 3'x3'x12' having 4 seperate compartments in each basket.You can get them in different sizes & shapes but that is the most common one that I use.I remember they cost around $125 a piece not counting labor or riprap.As far as size of riprap ,I call it number 1.nothing bigger then say 8"x8".I usually just call the stone quarry and tell the dispatcher we are filling baskets ,dont bring me pumpkin size riprap.Here is a link thebig450es to the gabion website I am sure they have a supplyer near you. www.gabionbaskets.net

What about using "mafia blocks" as they call them back east. The installation I did is holding up very well.
Ive used vera-loc block for walls before, the wall at home i used 42 pallets. The price would be alittle too much for this job lol. I'll look into the mini jumbo block, i also like the wire baskets.
The thing with wire baskets is, wire rusts... then you get rocks and clay raining down the mountain.
I like the idea of mafia blocks, and if I didnt have the money to fix it right, i'd fix it by selling the house.
Oh, and consult a lawyer before you move anything. I'll bet that the homeowner will have little say once the insurance company gets involved. And because you own and operate earthmoving equipment, that makes you a pro bro...
If he didn't have the money for the correct procedure and the engineer, I wouldn't touch it.

Selling the house with out an engineers report will affect the value seriously,forget the wig get a bonded engineer let him have the grief...

Common sense is not common practice
Does the homeowner have Homeowner's Insurance? If so... it should cover the cost of repairing something like this without the homeowner coming out of pocket for anything. If rust is a concern, there are a number of gabion systems available that spec epoxy coated wire, both for corrosion protection, and asthetics. MacAferri also offers a basked made out of geogrid.
Well, the homeower has been saving up for this, i told him homeowners is the way to go on this project. In my figures it looks like ill be moving about 120 cubic yards of material to get it to a 45 degree grade.
Not into doing this type work, but might try looking into spray foam used in trenchs to stop water flow, I think they have different types that are 10000psi thats better than concrete and it is easy to do, cut a trench the use the spray foam. Oil transfer lines use this method.
How much are the mafia blocks?I always thought they were cheap.
