Drainage System and the importance of it ….

We all know the damage water can do. When designing a retaining wall there are many factors that goes into it .One of the most important parts is a drainage system other’s include compaction, geo-grid and leveling pad some times called the footing   Without proper drainage this WILL happen and cost you this $$$$$$…..

No drainage : This will happen

In order for any retaining wall to function properly and remain sound ,a drainage system should be a integral part of the wall. Drain rock and perforated pipe should be used to create an effective drainage system.

With our retaining walls we add a minimum of 12 inches of drain rock from the back of the wall to the top of the wall . The perforated pipe is use to divert the water away from the retaining wall .

So as my friend Bruce at look at it as very cheap insurance….

  2. It’s true that water can do a lot of damage. I never thought about having drainage for a retaining wall. I guess that it is a huge problem. Those pictures that you have posted show some serious damage that water can do!
