Railroads are an integral part of our nation’s infrastructure, and Helms knows how important maintaining their structural integrity and operability is. Unfortunately, like everything else, soils beneath railroads and railbeds are subject to settling from water intrusion.
With our structural polyurethane resins that support over 14,000 lbs. per square foot, Helms Polyfoam can stabilize and lift railbeds back to their normal and safe levels. In fact, Helms recently succeeded in solving a railroad repair problem for one of our clients, Gulf Coast Sand, in Picayune, Mississippi.
For this client, a 75-foot section of railway approaching their railcar scale had settled 5-6 inches. This settling was causing inaccurate scale readings due to uneven weight distribution along the scale. When there’s a soil stabilization or settling problem, Helms has the solution!
In order to ensure even distribution of lift and stabilization, it was determined that varying depths of injections should be made. These injections were spaced on 4-foot centers, at a span 4 injections wide per track (one injection point on each outer rail and two injections inside of the rail track) for an approximate injection total of 80 injection points.
At each of the 80 total injection points, ½-inch galvanized tubes were probed to a depth of 6 feet and 4 feet, alternating at each injection point. On top of each 6- and 4-foot injection, expanding resins were injected into the shell mixture at each injection point for stabilization without adding additional lift to the track.
The result? Our injection pattern for Gulf Coast Sand created a soil squeeze where each injection point compressed against the adjacent points to create a solid, rock-hard mass below the surface!
The combination of a small on-site footprint, choosing the right product(s) for each repair project and implementing our years of professional experience each and every time ensures our customers are getting the best repair solution available – whether it’s for railroad repair, levees, bridges, etc.
Our customers can rest easy knowing they have received the best repair solution available and that the job was completed with professionalism and the utmost integrity!
