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….
