Ecobloc Modular System

Underground stormwater crates

Modular Underground Tanks — Our Flagship Stormwater Solution

Ecobloc plastic crate systems assemble into detention, retention, and infiltration tanks of virtually any volume. They install beneath parking lots, buildings, and landscapes where conventional concrete isn't practical.

Tested for HS-25 traffic loading, long-term creep resistance, and full inspectability, these systems give engineers a lightweight, certifiable alternative to poured-in-place vaults.
