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  http://www.davisons4seasons.com/ 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!
