Wisconsin Highway 106 (STH-106) was reconstructed over a marsh area approximately 3 years prior, and almost immediately began experiencing differential settlement issues.

Construction of a new Holiday Inn Express Hotel in Lexington, KY required engineered fill within the proposed parking lot area to achieve plan subgrade elevation.

A mine site in Elko, NV was experiencing trouble with the tunnels spread throughout the project site. The tunnel floors were susceptible to trapping moisture, creating problems for the mine workers and maintenance crews.

The Price River Terminal in Wellington, UT is the Uinta Oil Basin’s newest crude by rail transloading facility. During a portion of the rail extension project, soft clay and silt subgrade was encountered.

The Santa Barbara Airport is bordered by the wetland known as the Goleta Slough. Much of the airport area was built on fill material that was placed directly over the existing wetland soils with groundwater at only 4 – 5’ below grade.

The projects associated with parking lot and fire lane pavements utilized Mirafi® RS380i woven geosynthetic to reduce pavement thickness thus avoiding any conflict between over excavation/ grading and the existing underground utilities.

The parking lot at a medical facility in Rockford, IL was being updated and expanded. The pavement on the parking lot was cracking and had shown signs of failure for several years.

In August 2016, a wind component manufacturer in Pueblo, Colorado bid a project to expand their existing lay down yard with sub-soils that consisted of sandy clay over clay stone bedrock with the presence of shallow groundwater in several areas.

Potlatch Corporation had to deal with large quantities of unsuitable, saturated soils, generally a result from the constant watering and storage of logs.

NexLube needed to expand their container yard capacity for their Port of Tampa, Florida facility. The expansion lot had existing weak dredge sludge spoils at the surface that extended to some depths that would not support the anticipated container loads.

At the Naval Base in Point Loma California, soft pumping subgrade was discovered by the contractor when excavating for the dike wall footings.

The concrete road has settled and cracked, requiring layer over layer of concrete patching. The roadway finally failed and the owners decided to completely repair the worst section of the roadway.

The town of Palisade, located in Mesa County, needed to rebuild its Main Street to keep up with the growing diversity and increased traffic loading, in an expedient and cost-effective manner.

In the IMAX parking lot, poor foundation soils required a geosynthetic reinforcement solution to enable the engineers to design and construct the new permeable paver system.

With the need for added capacity to support growing markets, L&M lumber needed to expand their yard to store timber. The new area to be developed approximately 16,000m² consisted of a very soft silty clay material with a high water table.

The rainy season of the Pacific Northwest deteriorated the subgrade, causing construction delays.

The East Lake Sammamish is part of a regional trail system, and once fully developed, it will be part of a 44-mile-long regional urban trail corridor from Seattle’s Ballard neighborhood to Issaquah.

Castle Rock Construction Co. (CRCC) is the contractor for this $4 million safety improvement project at the interchange of I-76 and 96th Avenue.

In Eagle Mountain City, UT, new schools were planned to be built adjacent to a new roadway.The engineer on the project wanted to stabilize the fine-grained subgrade soils which showed some potential to collapse.

This project site was to be developed with four new commercial/industrial buildings.The buildings were surrounded by asphaltic concrete and Portland cement concrete pavements.

NC A&T University needed to replace two sections of roads running through the campus. The existing subgrade material was a poor silty/sandy soil.

Ankeny Community School District is building a new school, which is being constructed over an existing soft subgrade.

An office parking lot in Northern Illinois was experiencing soft soils that created drainage issues.

The new Children's Hospital of Philadelphia needed to maximize the available space while accounting for water seepage due to the high water table of the adjacent Schuylkill River.

The City of Thermal, (Coachella Valley) California was in desperate need of water and sewer improvements and investigated solutions provided by geosynthetics.

TenCate Geosynthetics worked with The Commonwealth of Massachusetts on the reconstruction of a deteriorated armored revetment system, which protects the 1.5 causeway and beachfront parking.

Several recent over-topping events eroded the grass causing significant damage to the existing spillway.

Flanders Memorial Road meandered through various grade changes with steep inclines and declines which had caused extreme wear and tear, and signs of fatigue.

A new bridge was being constructed over the Missouri River where saturated soil conditions required the need to remove water from under the pavement section at the bridge approaches.

Jefferson County Highway Department desired a solution for reconstruction that would minimize the over excavation volume of the wet, organic soils and still provide a firm construction platform for the flexible pavement roadway.

Canadian Pacific's continuous rail maintenance and safety program identified a section of track on a site northeast of Edmonton, Alberta that was subject to track settlement resulting in cross level variations

Cherry Island Landfill was built on an old dredge disposal site at the confluence of the Delaware and Christina Rivers in Wilmington, DE. The subsurface conditions at the landfill consist of very soft, compressible materials.

A large United States electric utility initiated the closure of a CCR surface impoundment in 2015.

This project required the complete removal of the existing concrete lanes and asphalt shoulders in both the east and west bound lanes of I-16 from mile marker 39 to mile marker 69 in Dublin, GA.

The existing asphalt pavement in The National Asphalt Pavement Association (NAPA) parking lot was experiencing considerable alligator cracking and was scheduled to be re-paved.

The challenge was to construct a new taxiway over areas that were built on tidal flats and land reclaimed from Boston Harbor. In 2007, the FAA approved construction of a new center field taxiway (Taxiway Mike) to alleviate airfield congestion.

The challenge was to connect two public beaches separated by armored slopes with an elevated pedestrian and bike path. The trail must also provide protection for a high speed rail line from the severe wave action of the Atlantic Ocean.

The challenge was to place access roads on damp clay on a very tight schedule with no time to dry the soil. Enbridge Ontario Wind Power LP (“Enbridge”) constructed a wind power project in the northern part of Kincardine, Ontario.

The Alaska Department of Transportation (AKDOT) continually faces frost heave problems in their roadways. This road performs a critical link in supporting the needs of moving oil from the North Slope to the lower 48 states.

The challenge was to create a larger storage yard over soils that had a very weak bearing capacity, while keeping construction costs to a minimum.

To accommodate increasing traffic demands, the road was to be widened by five metres in the northbound and southbound lanes over a one-kilometre.
