Maxiwall Design Software for Terraforce Walls

Maxiwall Pro upgrade:

We are happy to announce that Maxiwall Pro now includes important upgrades to ensure our users continue to optimize their workflow and remain in compliance with the most recent Design Standards.


  1. New AASHTO 2020 Simplified Design Methodology.  The new AASHTO 2020 Simplified Design methodology was recently released in the United States and represents the most up to date LRFD Methodology for MSE Walls.  Changes compared to previous versions include the use of the Coulomb Earth Pressure Theory which allows the inclusion of interface friction to reduce applied loads, and the application of Strip and Point Loading behind the Wall.
  2. Plan View Import.  The New Maxiwall allows users to portant the Grading and Plan information of the Wall directly from AutoCAD using the Awall2 CAD Tool.  More information about this Tool can be found at www.ctiware.com/awall.  For those of you who do not use AutoCAD, the Awall Web Tool can be used in a similar way.  This can be found at: http://www.ctiware.com/awallweb/awallweb.php
  3. New Graphics interface.  A completely overhauled graphics interface provides clearer, more precise diagrams and images, as well as accommodating smaller screens such as laptops.

Why Terracrete?

Terracrete hard lawn blocks hold many benefits for landscape designers. From an aesthetic point of view, they are very versatile – a grass driveway, a rustic gravel driveway or an attractive pattern of pavers can provide the finishing touch to a residence or development that is looking to stand out.
