Base course radius for an outside curve on a 4 ft (1.2 m) tall 6° retaining wall. Refer to the Radius Chart to confirm that the AB product you are using will accommodate the desired wall radius. The tightest or smallest radius at the top of any AB wall using full size block is 4 ft. (1.2 m), and 2.5 ft. (0.8 m) using the half width blocks.

For best results, don't plan out the curve of your concrete retaining wall freehand. This will make it very difficult to create consistent block spacing. Instead, either use a curve template or the "stick and string" method: pound a stake into the ground and tie a string the length of the radius of the curve that you want to create to the end of th...
Concrete building blocks come in many shapes and sizes. The best ones to use have angled ends. These will make it easier to position consistently than if you tried using straight-edged blocks.
In order to build stability into your wall, offset each course of blocks back ½-inch. Gravity keep your concrete retaining wall stable. Try to space the offsets as evenly as possible.
As you build higher levels, the curve will get tighter. This means that the joints will not be uniformly spaced. This will make staggering the upper courses more difficult to do if you rely solely on one size of concrete blocks. However, you can solve this problem by using blocks of smaller sizes or by cutting your own blocks to make staggering the...
Make sure your first few layers of concrete blocks are perfectly aligned and spaced. If your foundation is not even, the remaining layers will become increasingly imperfect, compromising the stability of your retaining wall.
Give yourself plenty of time to complete this project. Take frequent breaks to straighten your back, catch your breath and clear your mind. This will help you to avoid making mistakes and will help keep you on track. It is better to enlist the help of a friend or neighbor. This will speed up the bricklaying process and provide you with physical sup...

When placing geogrid along curved walls, the geogrid should follow the back of the lip on the retaining wall block. Simply slit the geogrid with a utility knife and either feather out or overlap to follow the curve. Inside Curves and Geogrid. Geogrid needs to have 100% coverage around any curve. To achieve this, additional layers need to be ...
