The Foundation of Reliable Infrastructure
When it comes to underground infrastructure, durability and reliability are non-negotiable. Precast concrete manholes play a crucial role in managing stormwater, wastewater, lift stations, wet wells, sumps, and catch basins. At Locke, we design and manufacture modular manhole solutions that streamline installation while ensuring long-term performance. With superior strength, customization options, and expert engineering, our precast manholes are built to meet the unique demands of every project.

Tailored to Your Needs
No two projects are the same, which is why we offer a diverse selection of round and rectangular manholes, including CenterPoint-approved structures for electrical, communication, and drainage applications. Our rectangular manholes can be custom-engineered up to 10x30x9.5 feet, available as single or multi-piece units. For round structures, we offer diameters from 4 to 12 feet, with standard heights up to 8 feet and the ability to exceed 20 feet in increments of 8-foot sections.

Customizable Covers and Lids
Every project has different requirements, which is why we offer fully customizable lids and covers. Whether you need cast iron, aluminum, stainless steel, or galvanized steel covers, our manholes can be designed to accommodate various load ratings. We also offer additional customization options, including embed plates, specific opening configurations, and doghouse entries to integrate seamlessly with existing structures.

Exceeding Industry Standards
At Locke, we don’t just meet industry standards—we exceed them. Our manholes are engineered with specialized coatings to provide chemical resistance, ensuring protection from corrosive environments. Additionally, our covers can be designed for heavy-duty applications, from pedestrian pathways to port and aircraft-rated loads. No matter the challenge, we deliver solutions that enhance durability and performance.
