I have a 60 foot long retaining wall. Goes from 2 feet to 5 feet. At a angle where it is 5' it is leaning. I would like to tear down the blocks are rebuild it. I have blocks that are 6" x 12" x 6" deep. They have the knobs on top with the interlock grooves. I hear people suggest geogrid. how do you connect it to the blocks? Also should a person build a double wide base? Right now doesn't have much backfill except dirt. I plan to put in a foot deep backfill of rock. What kind and best methods to prevent future problems.

There are only a couple of hard and fast rules that should be followed when building a retaining wall. One is that the wall should be designed to lean back toward the hilly area just slightly, in order to reduce what they call "batter"... another is that if you have any opportunity at all to curve the wall ever so slightly it will help keep it from toppling.
I don't see anywhere that you should make the base double wide. And the backfill should be of trash gravel or peagravel - nothing too large.
The geogrid is an enforcer of strength, adding to the blocks and design yet more strength. Here are two sites that may help: 1. http://www.usfabricsinc.com/products/stratageogrids.shtml

Happy Building!
