KeyWall® Design Software

The KeyWall Design Software allows the user to design or analyze gravity wall and soil reinforced wall sections for all Keystone structural units and most common soil reinforcement materials. KeyWall provides a number of different design methods from ASD to LRFD for the designer to consider. The current version includes:

  • 2010 AASHTO LRFD design methodology
  • NCMA 2nd and 3rd edition methodologies
  • Keystone Compac III and Keystone Standard III unit data
Note: Intended for use by design professionals, here to be connected to a form where you can request access to KeyWall Design Sofware.  Please note, KeyWall Design Software operates in a demo mode and requires product registration prior to printing and saving files.  Please contact Keystone for updates to the software or any additional data required.

 

Key Estimator™ Spreadsheet

Use the KeyEstimator spreadsheet (MS Excel) to quickly estimate the square feet of wall and caps, exterior grade concrete adhesive, drainage fill, reinforced fill and base leveling pad material that you will need to build a wall.

NOTE: The KeyEstimator Tool from Keystone is not intended to perform engineering design or analysis functions as those tasks are beyond the scope of a simple spreadsheet. Please refer to the Keystone Design Manual and KeyWall Design Software for the more rigorous considerations of retaining wall design. The responsibility for good engineering judgment, architectural considerations, and construction experience is the responsibility of professionals specializing in such work. Keystone accepts no responsibility for the improper use of this spreadsheet.
