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.

Some people like to use the phrase "nature is healing." However, in some cases, nature can't heal itself alone. That's where we come in. Recently, a homeowner in Maple Grove, Minnesota reached out to KG Landscape after struggling to revitalize a back yard that was simply failing to thrive. Despite what seemed like ample sunlight and water, the turf suffered from numerous thin and bare patches that refused to improve. To determine exactly why they couldn't get this yard to flourish on its own, our client asked us to assess the yard and determine a plan that could reinstate the lush green lawn they expected for their Maple Grove home.

Seldom will you find a piece of landscaping less desirable than the unintentional water feature. That's why a recent client in St. Paul, Minnesota's Macalester-Groveland neighborhood reached out to KG Landscape. Poor drainage in their yard had begun to allow standing water to accumulate, which not only damaged the lawn but was also beginning to make its way into the home's foundation. Our assignment was to determine why this water was pooling where it was, then find a way to divert it to a safer outlet. In order to do so and to improve the health of this St. Paul lawn, our team developed a system of catch basins and underground drain pipes to capture and redirect rainwater. Additionally, we restored the damage standing water had done to the lawn with a full topdressing treatment combined with seed blankets in the most critical areas of the lawn. Upon completing the project, we successfully resolved the yard's drainage issues while also bolstering the health of the lawn.
