ok so i got a wall install it is 54 ft long and 3.5 feet high. so i took out the old retaining wall which was made of rail ties. once itook these out i duge the ground until it seemed solid ther was only one spot the was a bit sponey at first in the corner before compaction. once i noticed this i dug it out a bit more. so i fill in the area for base material of road gravel so i can compact it, once i started to compact it most areas became really spongey. we have had alot of rain in the last bit before the job started. it was si spongey that when walking on it you could see it moving under you feet. My assumtion is that it is still wet there and that the ground is spongey from that, now my plan is to go back tomorrow and do the wall and the base material again. take out what is in place redo it and use 50% a gravel compacted then the other %50 of the base i am going to use 3\4 clean. any suggestions on this situation, need them asap.
