Disclaimer: This calculator provides preliminary estimates for informational purposes only based on simplified assumptions (Rankine theory, level backfill, no seismic). All retaining wall designs must be reviewed and approved by a qualified professional engineer considering site-specific conditions and local codes. Reinforcement design is not included.

Design Your Retaining Wall with Confidence – BETA

Planning a retaining wall project? Ensure its stability and safety with our easy-to-use Retaining Wall Calculator. This tool helps you perform preliminary checks for common failure modes based on standard engineering principles (Rankine theory).

Simply enter your wall’s dimensions (height, block type, footing size), select the soil type, and specify reinforcement details. The calculator will instantly provide factors of safety against sliding and overturning, as well as the estimated soil bearing pressure.

Key Features:

Analyze stability for various CMU block sizes (12×16, 8×16, 12×8).
Account for fully or partially grouted walls.
Select common soil types (Clay, Sand, Silt, Gravel).
Get instant results for Sliding FS, Overturning FS, and Soil Pressure.
