New home builder wall fail.
A client came in last week with a problem and with photos showing a failed retaining wall. I was asked by the client to inspect the wall and I found the builder had not installed any drain behind the wall. Another issue was the lack of crushed rock behind the wall and just earth was behind the wall. These two items are essential for the construction of a successful retaining wall. The crushed rock is used for several reasons easy flow of water to the drain and an ability to move unlike earth which just compacts over time. The drains are also required for the water to egress easily and be moved away from the wall. I wrote a report and the matter will be going to VCAT to get sorted out.
