It’s how you finish. Experience the Pinnacle Difference.

Effective stormwater management is vital for Mechanically Stabilized Earth (MSE) retaining walls. Controlling surface runoff and subsurface water prevents dangerous hydrostatic pressure build-up, internal soil erosion, and structural collapse. Proper integration with site drainage ensures long-term stability and extends the design life of the wall.

SOMETIMES YOU HAVE TO STOP AND TAKE IN THE VIEW.

Engineering excellence in action.

The Pinnacle crew has reached a towering milestone in Ramapo, NY, completing a massive Mechanically Stabilized Earth (MSE) retaining wall. Standing 73.5 feet tall and stretching 1,157 feet long, this impressive structure reaches just below the local tree canopy. It marks a major achievement in a broader 15-wall project encompassing over 142,000 square feet.

Incredible work, team! Take a well-deserved moment to take in that view and enjoy your moment of Zen.

Following our recent announcement welcoming three new professionals to the Pinnacle family, we are pleased to introduce the final addition to our leadership team.

Please join us in welcoming Cooper, our new Head of Corporate Security.

Cooper takes on this vital role with a strict focus on workplace morale and environmental threat management. His daily responsibilities include perimeter monitoring, tactical lunchroom surveillance, and implementing mandatory high-impact stress relief protocols for the team.

While he has already opted out of the standard corporate dress code and slept through his first round of onboarding, his commitment to keeping the office grounded is unparalleled.
We are proud to expand our roster with such a dedicated asset. Welcome to Pinnacle, Cooper.

In recognition of Construction Safety Week (May 4–8), Pinnacle Design/Build remains committed to more than building structures.

Our highest priority on every project is ensuring that every team member returns home safely to their family at the end of each day. We’re proud of the crew pictured here and grateful for the professionalism and dedication they bring to maintaining safe, successful projects every day.

For 30 years, Pinnacle's retaining walls have been the foundation of the critical infrastructure that you drive on, over, and around every day.

But some of the most important work happens where you can’t see it.

Our drilling, foundation, and earth retention solutions remove uncertainty below the surface, giving our clients the confidence to build everything above it.

Pinnacle - On top, from the bottom up.
