ShoreGuard Rebuilding Flood Ravaged Area
Hope Mills Lake Dam Restoration

Hope Mills , NC

A season of heavy rainfall and flooding washed away the embankments of the Hope Mills Lake. Today, the Town of Hope Mills is rebuilding the lake through the reconstruction of the Hope Mills Dam. This restoration project will affect 95 square miles of watershed and must withstand the impact of future natural events.

With an opportunity to work in the dry lakebed before another flood, ShoreGuard sheet piling is being driven up to 24 feet to provide the footing for the large concrete dam that will be completed sometime in 2009. This essential foundation support will contribute to the success of the project by protecting the dam from being undermined by the water that this lake will once again hold.

By providing a better value than any sheet piling in the world, ShoreGuard was the superior choice to complete this project.

 




Cleaning up Pennsylvania with CMI Sheet Piling
Indian Creek Watershed

Saltlick Township, Fayette County PA

The water from Indian Creek once flowed red with iron discharge from the old Melcroft No. 1 mine. The quality of the water had long been a significant public health and safety concern to local residents. The 3.5 million dollar Anna and Steve Gdosky Indian Creek Restoration Project was a cooperation of community members, the Mountain Watershed Association, the state Department of Environmental Protection and the state Natural Resources Conservation Service.

The project utilized a design developed by the U.S. Department of Agriculture and the state NRCS. Five separate ponds were constructed utilizing ShoreGuard vinyl sheet piling. Like many other government agencies, the NRCS chose vinyl sheet piling because of the inert properties of the material which will never rust, rot, corrode or decay.

Florida Gas Plant Site is contained using CMI Sheet Piling Solutions.
United States Enviornmental Protection Agency
Calumet, MI


In the Township of Calumet, Michigan, an industrial site, which belonged to the former Manufactured Gas Plant (MGP), contained hazardous substances that were migrating off-site. Given the assignment of containing the uncontrolled discharges of coal tar waste into a drainage ditch, the Environmental Protection Agency (EPA) utilized CMI ShoreGuard sheet piling to construct an impermeable barrier around the hazardous site.

The EPA chose the ShoreGuard SG525 profile because of its patented I-Beam locking system and full box design. Only CMI vinyl sheet piling profiles can provide such a water tight barrier to prevent further seepage. This level of performance cannot be obtained with other types of sheet piling or slurry systems. The panels were driven to varying depths down to 17 feet below ground surface (bgs) based on historic and Site Assessment soil and plume data. read more...

CMI Vinyl Sheet Piling: Get the Best for Less
Forsyth County Utility Commission

Winston-Salem, North Carolina

When the Forsyth County Utility Commission decided to build a concrete dam across the Yadkin River, they knew river containment and flood control would be a primary concern. The river’s tendency to flood meant the project had to be designed in a way to prevent the river from rechanneling around the dam during periods of high water levels. They decided to control the water with a CMI sheet piling cut-off wall. During the planning phase, the commission discovered that they could significantly reduce their costs by using CMI vinyl sheet piling. Project Engineer Jeff Coggins stated, “It was an economic decision. It was just cheaper to use vinyl.”

Creating the Best Barriers for the Job
Medley Landfill
Miami, FL


Waste Management, Inc. required a cut-off wall that would prevent water migration underground as well as on the surface. Affordability, ease of installation, as well as the corrosion and chemical-resistant properties made CMI vinyl sheet piling the best option for the job. The cut-off wall was installed at a rate of 300 linear feet per day which reduced the project cost by over $300,000.

Protect Vital Operations from Mother Nature
Phillips Petroleum

Sweeny, TX

Philips Petroleum faced a problem that many coastline businesses confront when a hurricane blew through their area and flooded a brand new power plant facility. To prevent future flood damage, they decided to build a six-foot floodwall to protect their facility. Philips initially considered steel sheet piling for the job, but instead chose CMI vinyl sheet piling based on cost savings as well as ease of installation. Due to the plant’s layout, they needed to install the wall in an area where large bulky equipment would have limited maneuverability. Since vinyl is significantly lighter than steel, they required far less heavy machinery for material transport and installation.

Stand Up to Harsh Marine Environments with a Core of Stability
US Army Corps of Engineers,
Wallaceville Dam
Wallaceville, TX


The USACOE required sheet piling to reinforce the dam and protect the spillway on the Trinity River lock system. The dam is exposed to salt water, so risk of corrosion was of primary concern. Vinyl was the clear choice above steel due to its corrosion-resistant properties. The USACOE was able to extend the service life of the dam by reinforcing it with a sheet piling capable of a
50-year design life.

Inert CMI Materials Add Levels of Control to Results
Chem Waste
Lake Charles, LA


Vinyl’s chemical resistance can provide more than just a protective barrier in waste disposal areas. By building a water control cut-off wall with sheet piling made from an inert material, Chem Waste was able to accurately monitor the groundwater.

National Park Service
Jefferson Memorial
Washington, DC


The Jefferson Memorial’s original construction, dating back to 1946, included a steel sheet piling wall around the base for foundation protection. When renovations started on the memorial, workers discovered that the original steel sheet piling had deteriorated from the salt water content of the swampy Washington DC terrain. Because of the scale and important nature of the project, they required a replacement material that would out-perform steel in those conditions. They chose CMI sheet piling for the project because it met their 100-year design life criteria.

Supporting Local Businesses Against Mother Nature
South Padre Island, La Quinta Hotel
South Padre Island, TX


South Padre Island is located in hurricane country, and to try to reduce flood damage, the island building codes required new structures to be built at higher elevations than many of the existing lots. The La Quinta Hotel solved this dilemma by building up the soil using CMI sheet piling. They reduced their costs by choosing vinyl over steel, and because vinyl requires less heavy machinery for transportation and installation than steel sheet piling, they were able to maneuver more easily in the small space between their property line and the beach front.

CMI Sheet Pile Protects Infrastructure and
Ecosystems Alike

US Fish and Wildlife, Hagerman National Wildlife Refuge
Sherman, TX


The Hagerman National Wildlife Refuge sees frequent fluctuations in water levels which can cause dirt roadways through the refuge to wash out. In this case, the US Fish and Wildlife Department was not interested in controlling the water or preventing the flooding. Instead, they viewed the change as part of the natural cycle of the habitat and wanted to find a way to ensure that their roads could withstand the flooding without eroding and washing away. They chose CMI vinyl sheet piling for two reasons. First, vinyl is an inert material that would not impact the chemical balance of the delicate ecosystem in which it was to be installed. Second, vinyl’s ease of installation meant they could shorten their installation time as much as possible to lessen the impact on the surrounding habitat.

CMI Sheet Piling Enhances Other BarrierMaterials and Reduces Overall Costs
US Army Corps of Engineers, Ram Island Causeway
Long Island, NY


CMI sheet piling was the product of choice for soil reinforcement along the Ram Island Causeway. The sheet piling was installed in combination with rip rap to prevent soil from sifting away and causing the road surface to settle. The durable, strong interlocking sheet piling created an effective barrier that reduced the amount of rip rap necessary to complete the project, and provided a longer-term solution than rip rap alone. Additionally, CMI’s sheet piling reduced the cost and surpassed the expected design life over steel sheet piling
