Retaining Wall Geogrid ?

Hello wvgmc1,

"I really don't know the difference."

Nor do I, but do what I do, look up the Manufacturer's Website.

Look on Mr Google's fine Search Engine, there are many references.

Have a look here:

Select your proposed product, and you have the info.....

Either Contact the manufacturer or the suppier you bought the blocks.

Either one should be able to tell you which grid you should use.

Actually the Manufacturer would be best, because they may prefer a different geogrid than your supplier is offering.

If you want a Retaining wall safe in all water-soaked seasons then you should go for foot shaped Precast concrete blocks say 2' wide

The foot should be projecting in about2',the wall(leg) 6' At transition from foot to leg you should have reinforcements--to resist toppling moments from slushy mud on vertical portion while it is bearing down on the foot. To take care of concave bends in the Retaining Wall plan--foot should taper down to say15"(from2'). Only SOME.

And between2' wide sections -purposely leave gaps for slush/seepage to leak out (weeping holes).

Let us not worry about 2XT/3XT

For retaining wall better to use uniaxial geogrids as the force is mainly in one direction. I think Colbond company has a nice design software for it. You may contect them. For general information on geogrids, geocomposites, and all geosynthetics check this blog.
