Hey everyone, we are doing a raised patio against a house that is a year old. What is everyones opinion on an overdig? (besides it being needed, which I know it is) How do you recomend I decide how deep to go with it? also, what about a water proofer on the foundation wall that will be against the patio? Thanks! Also, we always use modified stone for fill... I have been hearing others say clean stone is better? What are the opinions? I like the modified, havent had any problems, and I think I should stick to this. Thanks!
