Bentomat geosynthetic clay liners the global standard for gcls sodium bentonite based gcls provide an excellent hydraulic barrier in applications where leachate in direct contact with the gcl is relatively non aggressive or in composite lining applications where the gcl is overlain by a thermally welded geomembrane and hydrates from uptake.
Bentomat cl mat.
Landfill lining waste and recycling landfill.
Bentomat cl is designed for better performance under more variable conditions by providing permeabilities ranging from 10 to 1000 times lower than standard gcl s.
Cetco gcls are designed to meet the demands of any project.
The finished surface should be firm and unyielding without abrupt elevation changes.
4 2 when the gcl is placed over an earthen subgrade the subgrade surface must be in accordance with the project specifications.
Gcls are a great secondary or supportive layer used in conjunction.
Geosynthetic clay liners gcls are geotextile and bentonite composites typically sodium bentonite sandwiched between two layers of geotextile engineered for a variety of environmental containment applications.
Bentomat gda cl is the ideal solution for applications where the hydraulic performance of.
Ideal for applications where additional hydraulic performance is required the cl range incorporates a flexible plastic membrane liner that adds an extra layer of protection to the gcl.
The powdered bentonite clay is sandwiched between a woven and non woven geotextile resulting in a very strong robust product.
Bentomat gda is the perfect solution when it comes to greater depths of standing water because the flow through geosynthetic clay liners increases at higher hydraulic gradients.
Bentotex geosynthetic clay liner bentotex is a geosynthetic clay liner gcl.
Our experts can also assist in customizing solutions to meet your unique challenges.
This specification is intended for use as a general guideline for developing a specification for a specific project.
By adding an hdpe membrane this effect is significantly impeded without having to forgo the benefits of a bentonite mat.
Bentomat cl is a composite laminate reinforced gcl consisting of a layer of sodium bentonite between two geotextiles which are needlepunched together and laminated to a smooth flexible membrane.
Bentomat 200r is a non 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.
Geosynthetic clay liner specification guidelines.
Our extensive line of bentonite based and polymer enhanced gcls address design challenges such as hydrostatic pressure shear strength and chemical compatibility.
It is not intended as a substitute for a detailed specification which must be written to address site specific conditions.
