RetainPro Overview

IMPORTANT: As of June 2021, RetainPro's earth retention modules are now part of ENERCALC Structural Engineering Library (SEL).

The current specifications for ENERCALC Structural Engineering Library earth retention modules are available at

RetainPro helps civil and structural engineers save time and improve accuracy when designing and analyzing earth retention structures.

You can easily and accurately design and analyze nearly any cantilevered or restrained retaining wall, concrete or masonry, with just about any configuration and loading condition. Segmental retaining walls (with or without geogrids (MSE) too!

  • Loading conditions include axial, surcharges, adjacent footings, impact, wind, seismic (due to earth pressure and/or self-weight).
  • Stem can be divided and stepped for up to five changes in thickness, material, and reinforcing.
  • Immediate downloading after ordering or upgrading.
  • Select building code and RetainPro automatically inserts proper load factors, all of which are editable or set as defaults.
  • Conforms to applicable provisions of IBC 2018/CBC 2019, IBC 2015/CBC 2016, IBC 2012/CBC 2013, IBC 2009/CBC 2010, IBC 2006, ACI 318-14/-11/-08/-05, TMS 402-16, ACI 530-13/-11/-08/-05, and ASCE 7-16/-10/-05.
  • Soldier pile & segmental retaining walls.
  • Gabion gravity walls and multi-wythe large-block walls.
  • Design Status bar for overstress warnings.
  • Allows water table condition, including footing buoyancy.
