Bencor today is a reflection of its enhanced capabilities and extensive history - one that values integrity, ingenuity, and hard work.

Bencor has been at the forefront in the development and advancement of deep slurry wall construction and specialized grouting techniques since the introduction of these technologies into the North American market.

Since 1969, Bencor has undertaken and constructed many diverse projects, including large civil projects, featuring slurry diaphragm and cut off walls, drilled shafts and caissons, complicated underpinning, and deep foundations. Bencor has performed work in the United States, Canada, South America, Europe, and North Africa. 

Bencor has extensive experience in cut off wall construction, having completed many complex and demanding projects to depths of over 260 feet through existing dams with differential hydraulic heads of up to 90 feet, as well as other types of cutoff walls in difficult overburden and rock.

Our leadership team has been instrumental in guiding Bencor’s role as pioneers and developers of slurry diaphragm wall construction, and advancing the latest jet grouting and micropile technology within the industry. These individuals have written and co-authored a number of technical papers associated with these topics, including contributing a chapter, “Diaphragm/Slurry Walls” in the McGraw-Hill Publication, “Handbook of Temporary Structures in Construction.”

Record-setting and Award-winning Projects

Bencor has not only constructed the deepest, largest diameter, and the most number of deep diaphragm wall shafts in North America, but has also been involved in a number of record-setting and award-winning projects. Most recently, for example, The Blue Plains Tunnel in Washington, DC, won ENR Magazine's  Project of the Year 2016, for which Bencor design-built the slurry wall shafts including a unique figure-eight configuration. Another challenging project included the massive Inner Harbor Navigation Canal (IHNC) Lake Borgne Surge Barrier Floodwall in New Orleans, which was not only the largest civil works project ever awarded by the US Army Corps of Engineers, but also received awards such as the ASCE OPAL award for the Outstanding Civil Engineering Achievement of 2014.

New Parent Company (Keller)

Bencor (est. 1969) is now part of the Keller Group of Companies, complementing Keller’s existing product lines in North America and joining other Keller companies in providing expert geotechnical solutions and design/build services within the heavy civil construction industry. 

Bencor, formerly part of Layne Christensen Company’s geotechnical construction division, (Layne GEO), was purchased by Keller Foundations LLC, a member of Keller Group plc ("Keller") in August 2015. Bencor has decades of experience and a drive for innovation that has made it a leader in diaphragm slurry walls and various drilling and grouting technologies.

Keller Foundations LLC is located in Hanover, MD. Keller Group, plc is a global construction company based out of London, UK, with revenue of over £1.6 billion, and approximately 10,000 employees operating in more than 40 countries.

Predecessor Company Experience and Overview

In 1995, Layne Christensen Company purchased Fonditek International, followed by Hydro Group, Inc. in 1998. These companies each specialized in various segments of the geotechnical construction market, such as jet grouting, drilling and grouting, micropiles, anchors, etc. They were consolidated under one division in early 2000, and operated under the name Layne GeoConstruction. 

Over time, further related business units were purchased by Layne and added to the division: Moore & Taber in 2008 (grouting), Bencor Corporation of America in 2010 (slurry walls), and Fursol (software / data management) in 2012. The division was renamed Layne GEO in 2012. 

Keller Group plc acquired Layne GEO in August 2015, retaining its entire management team, along with all support and field personnel, equipment, and office locations. The acquisition was renamed Bencor Global, Inc., and is headquartered in Frisco, TX.
