We work for a builder that used to use them. All in all, I've done about 100 of them. Never had a problem with any of them. We only put down 8" of pea gravel. I believe that 2' is too much.

No problem
I've probablyput in the foundation for about fifteen or twenty duplex housing units that used Superior Walls. We put 2b limestone down 12" wide and 8" thick for the walls, then 2" of 1b on top of that. You had to be right on with the limestone grade, but the wall erectors would touch it up before they put them up. They were meticulous with placement and spacing, and did seal all the joints before they pulled the sections tight. We backfilled inside and out to floor subgrade, then waited for the modular units to be erected before we did anymore backfill. The only problem we had was when the builder has us backfill inside the garage unit with dirt instead of gravel. That wall pushed and had to be dug back out and straightened before it was backfilled correctly with 2b. Although it was a pain in the backside to do the work, I don't know of any other complaints or problems with this method here in western Pennsylvania.
Happy 4th of July to all, and please remember just what the 4th of July is all about. :usa

A Cat 320 with a hammer should have been there,job would have been taken care of. Blasting is not cheap anywhere and permit costs alone will prohibit it.Also,when firing a shot,if any equipment is close by be sure and shut it down.Otherwise you will bust the cranks from the concussion.My boss had to replace 5 a few years ago and that wasnt cheap.Running Cat equipment and shooting dynamite at the same time dont mix.:drinkup

First,have to agree with those that are down with Superior Walls.There is nothing close that resembles the word superior.They are absolute GARBAGE.They give excellent job security to tapers and painters because of all the cracks that will develop in the house.I have not had 1 customer who was totally happy with theirs--complete gimmickery.Now,for placement of perforated pipe--whether you're installing a collection type system such as in a footing or curtain drain or doing a leaching type system, such as leach fields for septic,or a possible mixture of the 2,writing on the pipe goes straight up,holes are down and even.This is not a preference--it's just a recognized practice that can be clearly seen in any and all building code manuals.When some builder tries telling me different,I will leave his site,because of course he will cut corners on something else,not use enough stone---the client will remember who was the excavator running the iron when problems arise.As for the need for footing drains,any and all excavated{below grade}foundations should have them to relieve hydraulic side pressure and to route water away.
