Ok, I am developing three lots right now where the back yards are DOGS and I am putting two 4' high AllanBlock walls in on all of them to try and get at least a little bit of flat land for swingsets, clubhouses, etc., for a total of 6 walls (plus each lot gets a wall in the front yard as well). I really wanted to curve the ends of the wall back into the bank, but when I got to the second course, it looked terrible on the outside radius. You could see a large gap where the two blocks below met and the "locking lip" is exposed. I followed the instructions for a "sharp turn" from the Ab installation guide but I can not get the wall to look presentable. I have about given up on the radius at this time, but I really think it looks nice with one...the first course sure looked good! On the bottom course, I broke off both of the "wings" and put the blocks flush with each other. Is that too tight a radius to work with on the other courses? Also, for the straight aways, I placed the blocks centered above the two below (split down the middle). I am using the 12 degree blocks if that matters. Any advice would be greatly appreciated (please don't tell me to buy a different kind of block...I have 600 of them (Grey AB collection) already on the deck). Thanks!
