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 $$$$$$…..

Notice no drain rock or drain pipe…

  • improper drainage will cause your retaining wall to fail...

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….

GeoGrid what is it ?

Geogrid is a geosynthetic material used to reinforce soils and similar materials. Geogrids are commonly used to reinforce retaining walls, sub-bases or sub soils below roads or structures. Soils pull apart under tension. Compared to soil, geogrids are stronger in tension. This fact allows them to transfer forces to a larger area of soil than would otherwise be the case.

Ok… Ok…. that’s the technical term…Hell I don’t even understand it (lol).

Geo-Grid All Access Construction

You may have to cut the geogrid at different widths depending on the plans…

When the weight of a retaining wall units along is not enough to retain soil loads geogrid will provide the additional soil reinforcement necessary for your wall stability.  A properly design wall can be constructed to heights exceeding 30-40 feet.

That’s still a little too technical so here it is….

It’s safe to say pretty much any retaining wall over 4 feet or with special requirements might need geogrid (Check with your local building department or engineer).

At All Access we try to keep it as simple as possible. Remember any of our retaining walls can be built using Keystone, Baselite ,Allen block, Belgard ,Redi-rock block system , Versa-Lok or any other system you may think of.

VERSA-LOK RETAINING WALL 

Introduction 

This retaining wall project took place in Mill Valley, CA in Marin County . One of nine counties of the San Francisco Bay Area. The Elliot’s found us on the internet.  We gave an estimate on this project in May 2011. Since the retaining wall was about seven feet tall we had to have it engineered and inspected. Along with their summer vacation we ended up starting the job in November 2011.

While we love all our clients, this was one of the best clients we’ve dealt with. Once we got the retaining  wall project going, they just looked out there back yard once in awhile and said it’s looking great for the most part.

PROJECT AND DESIGN:

The project was pretty simple. Customer had a failing wood retaining wall. They also wanted to add some more room in the backyard for entertainment purposes. They decided to go with the Versa-lok block retaining wall system in the Shasta color.

Over 100 yards of sand stone was removed

THE CHALLENGE:

The main challenge here was the sandstone rock we discovered behind the 20 yards of fill dirt which we had to remove. Once we discovered the sandstone, the customer and I came up with a game plan to only go back 8 feet instead of the original 10 feet to save time and money.

To speed up the process of getting the sandstone out we rented an excavator with a 750 pound Jack Hammer. This alone saved us about three days. Due to the limited room in the back yard we had to first remove over 100 yards of dirt. Then we brought approximate 100 yards of drain rock for the retaining wall.

Once these challenges were met, we were able to use our bobcat equipment to complete this job in about 15 days, including inspection. As with all of our retaining walls, we included a full French drainage system that tied into the customer’s existing drainage system.
