We all know the damage water can do. When designing a retaining wall there are many factors that go 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 $$$$$$…..
Notice no drain rock or drain pipe…
No drainage: This will happen
In order for any retaining wall to function properly and remain sound, a drainage system should be an 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 used 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….
Over 100 tons of drain rock
At All Access, we try to keep it as simple as possible. Remember any of our retaining walls can be built using Baselite Allen block, Belgard, Redi-rock block system, Versa-Lok, or any other system you may think of.
