How high can I build with Allan Block retaining wall blocks?

Written by: Kyle Huerd

The simple answer is…there isn’t a max height.  With that being said, there isn’t a reason to build a mile-high retaining wall when skyscrapers have more purpose to build rather than such a high earth structure.  

As walls get taller, reinforcement is required to keep it standing.  That reinforcement can be geogrid, anchors, or No-Fines concrete.  When the wall cannot stay vertical by just using the blocks, then reinforcement is used to achieve a taller height.  Without a limit to how high a retaining wall can be built, cost to benefit analysis will dictate how high you want to build your wall.
