In late November, EnviroRail, a railroad service contractor located in Omaha, NE, made the first step in changing the future of railroad-maintenance construction by licensing Mechanical Concrete®.

Mechanical Concrete®’s patented, innovative process takes a cylinder made from the tread portion of used, waste auto/truck tires and fills the cylinder with same-size gravel. This reuse of the tires creates a solid, sustainable and greener way to make foundations, road bases and repairs. This new time-saving process is fueled by EnviroRail’s nationally exclusive contract for Mechanical Concrete® to reuse waste semi-truck tires. Mechanical Concrete®’s patent allows the use of cylinders to create roads that aren’t as costly to maintain and won’t break down as quickly as most previously constructed roads do.

Samuel G. Bonasso, P.E., the inventor of Mechanical Concrete®, describes the simplicity of the process, “If you take a cylinder and fill it up with stone, it will harden up instantly, and that’s what happens with Mechanical Concrete.”

EnviroRail will use Mechanical Concrete®’s patented technology for track maintenance to support its major railroad customers across the United States. This partnership of experience and innovation is sure to be a game-changer for sustainable, green construction. Mechanical Concrete® boasts a system that is at least three times stronger than typical crushed stone road construction, resulting in roughly 75 percent less maintenance.

Jason Luce from EnviroRail said, “Traditionally, as part of the civil engineering industry, railroads are at an “only-construct-or-repair-if-needed-state” during the winter months. Our goal is to have a railroad test the product during the first couple of months this year, and as soon as the weather turns for the better, we will be at a launch point with Mechanical Concrete®”. This partnership promises to be the beginning of a new affordable, sustainable and greener chapter in railroad maintenance.
