Industry Specialist - Proven Reputation for Problem Solving

Positioned across the Rust Belt with offices in Johnstown, PA and Indianapolis, IN, we have grown as a company in the heart of our country’s aging and deteriorating infrastructure dealing with sewer and culvert systems, many of which are more than a century old. As storm and sanitary sewer system rehabilitation specialists, there are few problems our experienced team hasn’t tackled and solved. We understand the fastest and most economical ways to utilize trenchless technology and structural shotcrete to solve the growing issues of the United States’ infrastructure, and ensure we proactively solve our customers’ problems before they escalate into something worse.

Hands-on Approach - We Inspect the Problem

At National Gunite, we inspect all accessible pipes, culverts, and structures the old-fashioned way by strapping on our boots and waders and getting a firsthand look. We will not recommend a solution or provide a quote without fully understanding the problem and our customers’ expectations. As a result of this full understanding, we have near zero change order requests for our clients and deliver a first-class finished product that is both on time and on budget.

Engineering-Backed Analysis – Optimized Customer Results

With National Gunite’s proprietary Customized Pipelining Design Program, we determine the unique reinforcement specifications for each project, and engineer our rehabilitation to be the most cost-effective, durable, and optimized fully structural design. Our customers can be confident knowing that their project is not over nor under engineered.

Advantages of Shotcrete
    Structural integrity with high strength, low permeability, and high durability
    Avoid costly and unnecessary inconveniences to public traffic and local businesses and first responders
    Trenchless technology means bottom-line savings compared to the cost of replacing pipe
    Avoid the headaches and delays of replacing pipe (e.g. disrupting or relocating existing utilities)
    Fully Structural Repairs applicable to all shapes (ovals, arches, circular, square, symmetrical, asymmetrical, etc.)
    Smooth finish of shotcrete reduces the roughness of a pipe (Manning’s coefficient)
    Staging up to hundreds of feet away if necessary and only manhole access needed
    Superior structural reinforcement than repair solutions such as polymer coatings & slip lining
We Handle Projects of All Sizes - Large & Small
Manhole BeforeManhole After
    This deteriorating manhole was part of a 42-inch diameter brick sewer main that NG was rehabilitating.
    The manhole was rehabilitated in conjunction with the sewer main rehabilitation to create a monolithic structure and add many years of life to the system.
Bulkhead BeforeBulkhead After
    Our crew made permitted confined space entry into this steel retention tank. A layer of stucco netting was installed and anchored to the sides of the tank to ensure a mechanical bond of the shotcrete to the failing bulkhead.
    A layer of 2” x 2”, 12-gauge, galvanized wire mesh was installed over the netting, then #4 half inch rebar was tied to the mesh for added strength. Finally, a nominal thickness of 6” of shotcrete was applied.
