Bentomat® CL
|
Bentomat® CL is a reinforced GCL composed of two carrier geotextiles needlepunched together to encapsulate a layer of Volclay sodium bentonite. A composite lamination gives the GCL excellent hydraulic performance and provides puncture and tensile strengths beyond conventional plastic membranes. Bentomat CL is ideal for landfills, ponds, surface impoundments and other containment projects.

Bentomat® CLT
|
Bentomat® CLT is a reinforced GCL consisting of a layer of Volclay® sodium bentonite between two geotextiles, which are needlepunched together and laminated with a flexible textured HDPE sheet. The addition of the HDPE sheet to the GCL increases the hydraulic resistance by an order of magnitude over that of standard GCLs. The textured surface of the HDPE sheet also increases the interface friction between the GCL and adjacent substrate when a greater interface friction is required on certain projects. This product is mainly used in liquid containment and landfill cap applications, but the versatility of the product allows it to be considered in many other applications.

Bentomat® DN
|
Bentomat® DN is a reinforced needlepunched GCL that not only has high internal shear strength, but also provides excellent interface friction on both sides of the GCL. Bentomat DN is ideally suited for steep-slope liner/cover systems where intimate geomembrane contact is less critical than overall liner system stability.
Head Pressure
| For low or high head applications |
| Permeability 5 x 10-9 cm/sec |
Shear
| Most lining applications with slopes > 3H:1V |

Bentomat® SDN
|
Bentomat® SDNis a reinforced needlepunched GCL that encapsulates a layer of Volclay sodium bentonite between two nonwoven geotextiles needlepunched together for high internal shear strength and good interface friction performances. Bentomat SDN may be a cost effective alternative for steep slope liner/cover systems where overall liner system stability is important.

Bentomat® ST
|
Bentomat® ST is a reinforced GCL consisting of a layer of Volclay® sodium bentonite encapsulated between two geotextiles, needlepunched together for maximum performance under a wide variety of field conditions. This integrated matrix of bentonite and needlepunced fibers provides high shear strength and allows Bentomat to maintain low permeability. Bentomat ST has a woven, slit-film upper geotextile for maximizing intimate contact in composite liner systems.
