Hey guys. I dont know if my brain isnt working correctly because i'm yet to have my first cup of coffee....or i just simply do not know the answer. Here goes... I have a customer that has a CMU wall that is on the edge of catostrophic failure right down the middle. It must be replaced. Im selling him on the advantages of SRW walls. Now, Before giving my estimate I need to figure one thing out. Is it possible to pull down the old wall while leaving the existing pavement it is retaining? The answer that I have in my head is no....But if anyone has doen this and knows a way chime in. my thinking is that during excavation the base for the ashpalt is going to get seriously undermined. The wall is currently around 4 feet high. The other thing is...obviously this wall needs grid. I think the ashpalt needs to be cut back to the appropriate depth, back filled, and re paved. right? Going to speak with the owner this afternoon.
