ASDIP RETAIN Retaining Wall Design Software

Complete Your Retaining Wall Design Easily Within Minutes


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

ASDIP RETAIN software is also able to design block retaining wall per the latest MSJC provisions. This software substantially simplifies time-consuming calculations for structural engineering design.

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

 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."

Cantilever walls can be reinforced with counterforts, which are vertical elements, perpendicular to the stem, acting as cantilever beams. In such a wall, the stem and the heel act as continuous slabs spanning horizontally between counterforts, and the toe acts as a cantilever beam. Since the wall is stiffer than the typical cantilever stem wall, the engineer may prefer to use the "at-rest" backfill pressure rather than the active condition.

The counterfort retaining wall 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, counterfort, heel, toe and key, for bending and shear, under the combined factored loads.

This software performs the concrete retaining wall design based upon Ultimate Strength Design Method per ACI 318,  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, counterfort, 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.

The wall may be supported on piles, and the software will calculate the pile reactions., and compares them versus the pile capacity in compression, tension, and lateral. Up to three rows of piles may be modeled, and piles may be vertical or batter. The software designs the pile cap. For pile foundations, the pile type, spacing, and capacity is required.



The program checks the wall stability for the service combined loads and performs the concrete design of the stem, counterfort, toe, heel and key for the factored combined loads. In each particular case the controlling load combination is identified and reported.

The retaining wall design is performed by analyzing the stem as a concrete slab spanning between the counterforts, which in turn are designed as cantilever beams ASDIP RETAIN generates a graphical view of the designed retaining wall and the resulting pressures and forces, as shown. The program also generates the moment and the shear diagrams for every load combination, as well as a view of the construction section and elevation with the reinforcement information. 

A detailed step-by-step report is available to the touch of a tab, which is updated with every new change. In addition, ASDIP RETAIN uses a pre-formatted colorful text-with-values output for easier identification of the problem areas.

 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!!”
