Highly Efficient Design and Analysis Software

Software Descriptions


REA Software

REA Software is the solution for designing Segmental, Precast Modular, Green Walls and Slope, or other Gravity or Reinforced retaining walls.

REA Analysis

REA Analysis is the primary design tool for looking at retaining wall design. Choose the face unit and the soil reinforcing, input the geometry and soil parameters and the program develops a preliminary design section. Global stability, compound stability, and water design options are included.

REA Analysis & Layout

Analysis and Layout combine the design engine of the REA Analysis program with the CAD capability of inputting the wall geometry (stations, top of wall, bottom of wall, station geometry), drawing the wall, and analyzing each wall section.

REA Analysis & CADD

Analysis and CADD have all the features of the REA Analysis and Layout with the advantage that the program runs as a library inside of AutoCAD(TM), making the design a one-step process from inputting the geometry and calculating the wall to printing construction drawings.

Data Files

REA Data Files

Data files contain the data for both the geogrid reinforcing and the block face. We have over 90 different face options, so each is in a separate directory.

(If you have a proprietary version of the software, only those specific data files will load and run.)

Geogrid Reinforcing

Tutorials and Training

The software is easy to use but complicated to learn.
We have included PowerPoint files with a step by step walkthrough and YouTube Videos of the software in action. As we get more time we will develop more tools to help you navigate the software.


NCMA Best Practices

In 2016, NCMA put together a "Best Practices Guide" for segmental retaining walls. It repeats much of the information in the NCMA Design Manual but has a lot of new information and best practices that help with wall design and construction. Download!
