ASDIP RETAIN Structural Engineering Software

​Design Your Retaining Walls Easily Within Minutes


ASDIP RETAIN is a structural engineering software utilized by engineers for design of retaining walls. ASDIP RETAIN is based upon the latest IBC / ACI 318 specifications.

ASDIP RETAIN software is also able to design masonry stems per the latest MSJC provisions. ASDIP RETAIN substantially simplifies time-consuming calculations for structural engineering design.

The new version 4 features: Retaining walls on piles, Two-story basement walls, and Counterfort retaining walls.

  • 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.
  • Much, much more...


 Love your retaining wall program and its ability to switch between US and metric units so easily. I returned my Retain Pro software after realizing that ASDIP is much better. Love your GUI."

Sometimes movement of the wall is restrained at the top, as in a basement. In such a wall, the overturning is prevented. The stem acts as a supported beam and the heel and toe of such a wall act as cantilever beams. Since the wall cannot deflect, the backfill pressure is generally the at-rest condition rather than active condition.

The design involves two major steps: the first one is the evaluation of the stability of the whole structure under the service loads, which includes the settlement and sliding failure modes, and the second one is the design of the different components, such as the stem, heel, toe and key, for bending and shear, under the combined factored loads.

The stem can be either concrete or masonry. This software performs the concrete design based upon Ultimate Strength Design Method per ACI 318, and the masonry design per MSJC.. The lateral pressures are calculated either per At-rest, Rankine, Coulomb, or Equivalent Fluid theories. Seismic design of the backfill and water table. Load combinations per the latest IBC / ASCE 7.


The input data required includes the geometry of the backfill, stem, toe, heel and key. In addition, the program accepts a number of load cases, such as surcharge (strap, uniform and/or concentrated), wind and seismic. The reinforcing steel may be specified and customized using multiple options.



This structural engineering software checks wall stability for service combined loads and performs strength design of stem, toe, heel, and key for factored combined loads. In each software calculation controlling load combination is identified and reported.

A detailed step-by-step report is available in page tabs. All page tabs are updated with every design change. ASDIP RETAIN uses pre-formatted, colorful, text-with-values output for easy identification of design defects.

ASDIP RETAIN generates a graphical view of designed retaining wall and resulting pressures and forces. This structural engineering software generates the moment and the shear diagrams for every load combination and including the construction section and elevation with steel reinforcement information. Rebar can be optimized.

 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!!”
