The retaining wall I'm building goes from about 2 feet to about 7 feet high. At it's tallest point, my wall is approximately 2-3 feet thick at the base and narrows to about 18 inches as it rises to the top. I start off at the base with the biggest flattest boulders I could find; then, I progresssively stack smaller flat stones as the wall rises. All throughout the wall building, I interlock the stones as best as I can. This is particularly important with the right angles if one is joining two walls at 90 degrees. Because the wall is so high, it's also important to vertically slope the wall at a slight angle....otherwise the wall would most certainly topple (likely through the freeze/thaw cycles).
Bob, needless to say, pictures would be appreciated. Even during construction. I'll try to get some of my brother's - if he has a digital camera, maybe sooner than later.
Yep....I've got the pictures, but the wall is still in process of being finished. I should be finished this fall. My problem is I don't have a digital camera. I have to take pics using my 35mm SLR, then I have to finish the roll, and scan prints as a jpg file. I thought I would wait until the wall was finished then I could post pics of the wall from start to finish. Sometime this fall I'll post here or I'll start another thread.
