What is Bentomat used for?
Bentomat® 200R is frequently used in environmental containment applications and is a high-performance, cost-effective alternative to compacted clay liners.
What is Bentomat?
Bentomat® ST is a reinforced bentonite-based geosynthetic clay liner (GCL) comprised of a polypropylene woven geotextile and a polypropylene nonwoven geotextile which are needle-punched together, encapsulating a layer of sodium bentonite clay between the two textiles.
How do you install geosynthetic clay liner?
Installing a geosynthetic clay liner
- Step 1 – Excavate your area for lining. Excavate the area a minimum of 12 inches deeper than your finished grade.
- Step 2 – Prep the area for liner installation. Make sure the subgrade is free of all rocks and debris.
- Step 3 – Installing the geosynthetic clay liners.
What is in bentonite clay?
Bentonite clay contains natural minerals such as calcium, magnesium, and iron, which may provide additional benefits. Bentonite clay forms from volcanic ash. It gets its name from Fort Benton in Wyoming, where it occurs in large amounts.
What is the core of GCL made of?
Bentonite composed predominantly (>70%) of montmorillonite or other expansive clays, are preferred and most commonly used in GCLs. A general GCL construction would consist of two layers of geosynthetics stitched together enclosing a layer of natural or processed sodium bentonite.
How do you install bentonite?
Mix soil with bentonite at that rate in lbs/square foot. Thoroughly blend the soil and dry granular bentonite until the mixture is uniform. Add 3 cups of water to the soil bentonite mixture and mix again until moisture is evenly distributed. Firmly tamp the soil/bentonite mixture into the bottom of the bucket.
Which is the largest group of geosynthetics?
Geotextiles and geomembranes are the two largest groups of geosynthetics, according to the Geosynthetic Research Institute (GRI), with geogrids representing a rapidly growing segment of the industry.
How much does bentonite cost?
In 2020, the average bentonite price stood at approximately 98 U.S. dollars per ton. Bentonite is a type of clay along with ball clay, common clay, and fire clay.

What are the different configurations of the Bentomat?
BENTOMAT is available in several configurations to meet hydraulic performance requirements. The 200R, ST and DN configurations typically meet hydraulic performance requirements in relatively low hydrostatic conditions.
How much does a Bentomat GCL need to weigh?
It is the engineer’s and owner’s responsibility to provide construction quality assurance (CQA) for the installation, to ensure that the installation has been executed properly. This document covers only installation procedures. 2 EQUIPMENT REQUIREMENTS 2.1CETCO GCLs are delivered in rolls weighing 2,600-2,950 lbs (1180-1340 kg).
Is the Bentomat needle punch density non reinforced?
BENTOMAT is available in a non-reinforced configuration to allow maximum value for your site. It is also available with the industry leading highest needle-punch density providing maximum performance when high internal shear strength is needed.
Where is the best place to store Bentomat Claymax?
BENTOMAT/CLAYMAX Installation Guidelines 5 of 15 3.7Rolls should be stored at the job site away from high-traffic areas but sufficiently close to the active work area to minimize handling. The designated storage area should be flat, dry and stable.
