ECT Manufacturing provides a comprehensive selection of heavy-duty square steel vaults engineered to safeguard sensitive tank hardware and monitoring equipment in demanding environments. Every square vault in our inventory, including our popular 12", 18", and 24" sizes, is manufactured to meet rigorous AASHTO H20 wheel load ratings, making them the industry standard for installation in high-traffic areas like gas stations, loading docks, and municipal roadways. These traffic-rated well vaults are designed with a low-profile footprint that protects subsurface piping while ensuring seamless access for environmental inspections, cleaning, and equipment maintenance.
Our hinged, locking, and water-resistant designs prioritize both security and ease of use. Featuring reinforced steel construction and integrated gaskets, these vaults prevent surface water infiltration and unauthorized access, ensuring the integrity of your monitoring well system. Whether you require a standard square manhole or a specialized lift-assisted lid for larger 24" models, our products are built to withstand heavy axial loads without compromising accessibility. By choosing ECT Manufacturing’s H20-rated square vaults, environmental professionals and drillers receive a durable, field-proven solution that meets strict regulatory compliance for well protection and subsurface access.
