Engineering and Materials for Your Retaining Wall Projects
PE-stamped plans in 40+ states. U.S.-made materials. Responsive support from first sketch to final inspection.
One Partner. Three pillars.
Design
PE-stamped retaining wall designs in 40+ states. MSE walls, soldier pile, soil nail, wire walls, sound barriers, and more — from preliminary layout to construction-ready drawings.
Supply
Geogrid, geotextiles, welded wire forms, facing systems, and accessories — coordinated with your design and delivered to your site. American-made options available from U.S.-based manufacturers.
Support
Engineering support from pre-construction through final inspection—including RFIs, field modifications, and real-time problem-solving. Plus ER Design Studio software and practical education through Earth Retention U.
Design + Supply + Support
for your earth retention project
By The Numbers…
• 25M+ sq ft of retaining wall designs completed
• 500+ projects per year entering our pipeline
• 6 licensed Professional Engineers on staff
• 40+ states with active PE registrations
• $75M+ in materials supplied to date
How We Work:
FROM CONCEPT TO CREATION
1) We get involved early — preliminary designs, site reviews, and quantities you can bid on.
2) We engineer it — full stability analysis, PE-stamped plans, construction-ready drawings.
3) We supply it — materials coordinated with your design and your schedule.
4) We stay with it — RFIs, field modifications, and problem-solving through construction.

Helipad Retaining Wall
The Team Behind 25 Million Square Feet
Earth Retention started in 2009 with one engineer and a commitment to doing retaining wall work the right way. Today we're a team of engineers, designers, and professionals working across the country — with 6 licensed PEs, regional engineering teams, and a track record that includes some of the most complex retaining wall projects in the nation.
Tools for the Industry
(formerly CTIware)
ER Design Studio
Retaining wall design software built by retaining wall engineers. ER Design Studio connects MSE analysis, CAD layout, quantities, reports, and construction drawings in one practical workflow.
Three days of work → three hours.
Earth Retention U
Practical education for engineers, contractors, and other retaining wall professionals. Request a lunch-and-learn or explore software tutorials and technical resources through the Earth Retention U YouTube channel.
A practical, field-focused PDF for contractors, owners, and engineers—spot issues early, prevent callbacks, and protect your schedule and budget.
The warning signs your wall is headed for trouble (and what to check first)
Drainage + backfill mistakes that cause failures and expensive rework
Compaction, geogrid, and reinforcement pitfalls that weaken performance
Common “looks fine today” errors that show up months later
A quick checklist you can use on-site or during plan review
