Drainage Behind Retaining Wall: How to Stop Retaining Walls from Failing
Why do retaining walls fail?
There are many reasons why a retaining wall will fail. However, the unifying thread through all of those failures is water. Walls fail because the builder did not use enough class 5 fill. Without the right amount of base material, water builds up underneath the wall and pushes the base layer out. Retaining walls also fail because the base layer was not leveled properly. An unlevel base layer allows areas for water to wash away certain sections more than others, which creates an unstable wall. In other failed walls, we’ve seen water collect behind the wall. This collected water freezes and expands which pushes on the wall, causing it to fall over. The common thread through all of these problems is improper preparation for water.

Where All That Water Is Actually Coming From Your backyard stays wet. You've noticed the soggy spots, the mud, maybe some frost heave damage to your patio or fence. You're thinking about French drains. But before you start digging trenches, look up. A huge amount of water hitting your yard isn't coming from rain falling on the lawn. It's coming from your roof. A moderate rainfall on a typical Plymouth home puts hundreds of gallons through your gutter system. Every bit of that water exits through your downspouts. Where it goes from there determines whether you have a drainage problem or not. Then there's your sump pump. Every time it kicks on, it's pushing water out of your basement and into your yard. On a wet property, that pump might run dozens of times a day. All that water has to go somewhere. If your downspouts dump water next to your foundation and your sump pump discharges into a side yard that drains toward your backyard, you're adding water to an already saturated situation. French drains alone might not be enough. You need to manage the sources. The Problem With Surface Discharge Most downspouts in Plymouth end with a splash block or a short extension that dumps water a few feet from the foundation. That's technically moving water away from the house, but not far enough.
