As an alternative, please use our Design Table Creator (link below) for basic calculation for single skin gravity walls:
Design table creator for single skin Terraforce walls. Use this interactive excel sheet to work out the design values – number of blocks, wall height and recommended setback – for most Terraforce blocks.
PLEASE NOTE: These design tables are intended to assist in estimating the cost of a proposed gravity retaining wall with Terraforce blocks. For a small fee, our TERRASAFE design service can provide a more accurate design.
For the design of composite retaining walls, i.e. structures with mechanically stabilised backfill or with additional reinforcing (double row of blocks, R.C. infill etc.) you are welcome to consult our free Maxiwall Pro software or Terrasafe design service (fee-based).

Maxiwall Pro allows Designers to easily produce complete Wall Designs utilizing the award-winning Terraforce line of Concrete Retaining Wall Block (CRB) wall products. With all Block and Geogrid information preloaded, Designers can select from a wide range of proven Terraforce systems from easy to navigate drop-down menus.
Compared to other MSE Design Software options, Maxiwall Pro increases design efficiency, improves accuracy, and promotes a seamless flow of information between design stages and parties. It generates full wall layouts with accurate quantity estimates and comprehensive reports. The Calculation Engine can simultaneously run Static, Seismic, and Internal Compound Stability (ICS) Analysis in accordance to National Concrete Masonry Association (NCMA), American Association of State Highway and Transportation Officials (AASHTO), Standard for Load and Resistance Factor Design (LRFD), AU (Australian Standard), and British Standard Design Methodologies.
Please note this is not a turnkey solution, it is essential to familiarise yourself with the software by going through the step by step tutorials available here: www.ctiware.com/tutorials
Design calculations performed by Maxiwall Pro should be checked and verified by a registered Professional Engineer who is familiar with the site conditions and project materials. The calculations performed by Maxiwall Pro, the Design Software for Segmental Retaining Walls are for PRELIMINARY PURPOSES ONLY. Rigorous laboratory tests were conducted pertaining to interblock shear resistance, whole block compressive strength and geogrid pull-out resistance. In the pull-out tests, the primary failure was rupture of the geogrid outside the blocks and performance was found to be above average, based on experience with a large number of systems tested over many years.
