You’re building a wall that has a curve in it, but you
aren’t sure what the radius of the base row should be. What do you do? Luckily,
here at Allan Block we have a few useful tools to help you figure out exactly
what your curved wall’s radius should be.
One of the most useful tools for finding your radius is the
AB Radius Chart. This handy guide gives you a quick way to estimate the minimum
radius that the bottom of wall can be, depending on what block you use and the
height of the curve.

Another valuable resource would be the “Curves
& Serpentines” page on the Allan Block website. This page will not only
give you more information about what factors of the wall will affect its radius,
but will also provide useful tips and diagrams showing how to construct your
curved walls correctly.
If you look through the two options listed above and still
can’t determine what the radius of your wall should be, we suggest that you use
our third, and most valuable, resource – your local rep or the the Allan Block
Staff. If you call or email in with any questions regarding curves in retaining
walls, we will always be here to share our knowledge with you and provide a
straight-forward answer for your not-so-straight wall.
