Key benefits:

  • Quickly model your retaining walls with the simple and efficient graphical user interface.
  • Confidently optimize your design and comply with design Code provisions.
  • Impress clients and plan-checkers with eye-catching condensed or detailed reports.
  • Extensive documentation, solved examples, and blog posts to guide you throughout the software.
  • Use your valuable time wisely while ASDIP RETAIN does the hard work for you.


  • Any Windows® Operating System. No additional software required.
  • Full compliance with:
    • IBC-12
    • ACI 318-11
    • MSJC-11
  • Stem material can be concrete, masonry, or combination of both.
  • The restrained walls can be either fixed or pinned at base.
  • Full set of design code load combinations.
  • Specify water table location in the backfill.
  • Customizable design criteria, options, and conditions.
  • Three different unit systems available:
    • US (in, ft, Kip, ksi)
    • SI (cm, m, N, MPa)
    • MKS (cm, m, Tn, Kg/cm2)
  • Rich user interface to model the geometry, materials, loads and rebars.
  • Tapered stem (either at toe or heel side).
  • Either Rankine, Coulomb, or Equivalent Fluid soil pressure theories.
  • Multiple loading including surcharge, wind, and seismic.
  • A strip surcharge load can be modeled and wall pressures are calculated.

Calculation results:

  • Check stability forces, shear, and moment diagrams per load combination.
  • Graphic plot moment and shear diagrams to optimize reinforcing bars.
  • Complete stability analysis for overturning, sliding, and bearing.
  • Graphic plot of moment and shear capacity.
  • Graphic display of forces and pressures acting upon the wall.
  • Concrete design of stem, toe, heel, and key.
  • Software finds controlling load combination for each component in bending and in shear.
  • Granular checking of stability and strength by load combination.
  • Water buoyancy effect included.
  • Detailed step-by-step reports with exposed formulas and Code references.
  • Combined text-with-values output message updated with each design change.
  • Outstanding output with Print Preview.
  • Three ways to show the calculations: At-a-Glance, Condensed, and Detailed.
  • Construction sketch generation of retaining wall updated with each change.


  • Project Manager handles calculations and file management.
  • You are in complete control of every single aspect of the design.
  • Design your retaining walls within minutes (not hours).
  • Verify every design step quickly. Not a “black box”.
  • No silly assumptions or math shortcuts. Confident, accurate, and reliable results.
  • Focus your attention on engineering, and let ASDIP RETAIN handle all the mathematical complexity.
  • Multiple calculations stored in a single project file.
  • Safely create, organize, manage, and store your electronic calculations.

“I’ve been using SAP2000 for a while to design continuous concrete beams, but have never been happy with all the work it takes to produce a decent easy to read report (specially for old-fashion town engineers). The reports that ASDIP Concrete generates couldn’t be any better. It shows all the math, equations, code references, load combinations, and, what I like the most is the reinforcement detailing. I only got the ASDIP Concrete module and now I’m considering buying the rest.”

“I was using Enercalc’s retaining wall module for wall design. It was cumbersome and glitchy. I needed a change and found ASDIP retaining wall software and was immediately impressed. The interface is clean and easy to use. The input options are located in logical tabs and provide me with all of the options that I need. I had one issue using the program due to my computer missing a windows install file, and Javier quickly helped me solve this. The install file was not related to the ASDIP software. Great software and Support!!”

“I Love how you investigate features in the Steel Program that I have suggested. The latest feature of adding the 0.8 stiffness factor for the Direct Design method works great. Your Software really is First Class and you provide First Class Support.”

We have been working with the ASDIP software suite for a few months and have found it to be a valuable tool in design of our structural elements.  The platform is user-friendly and there are immediate results when running the analysis.  It has helped to cut our analysis time in half.  We are a small but growing firm.  The value we get from the ASDIP platform far exceeds the cost of the programs.

The suite of design programs ASDIP is an excellent complement to the analysis of concrete and steel structures. We use them in most of our important structural projects such as tall buildings, industrial plants and special projects. The results are presented in a format that is useful to keep track of the calculations, and the software easily allows you to change the input and optimize the results.

Thanks for working with me the continuous ledge problem. This aspect plus the other concrete design solutions in the software, I think will be valuable to me in my work.

I recently purchased all four of the ASDIP structural engineering software modules. After using this engineering software for a few months I believe it works very well for its intended purpose. ASDIP is very simple to use, is reasonably priced, and the calculation output is organized with a nice looking readable layout.

I’ve used Mr Encinas’ software for designing composite steel beams, and found it easy to use, surprisingly flexible (for a “fill in the blanks” interface), and best of all, largely self documenting. I’m an engineer who always struggles with documenting calculations owing to time constraints. Being able to print out a nicely-formatted output that reflects a classic hand-calculation approach is a boon. I highly recommend this product.

Regards, and thanks for a great software and the superlative customer support!
