BENTOCARPET is a geosynthetic clay liner (GCL) manufactured from the equally distributed, high swelling sodium activated bentonite granules, placed between carefully selected non-woven and woven geotextiles which are mechanically bonded by special needle-punching method (needle-punching through all components) in order to achieve desirable shear resistance.

Geotextiles offer a long lasting resistance to physical or chemical break-down under difficult conditions, while high swelling and low hydraulic permeability of bentonite provide an effective hydraulic sealing. Bentonite granules are produced from specially selected bentonite with montmorillonite content of ≥85%, with continuous careful exploitation and processing monitoring.

A specific design and placement of needles, along with the selected geotextiles and high-quality bentonite granules, make BENTOCARPET perfect choice for the construction of durable, self-healing hydraulic barriers in various construction projects.

Due to its exceptional properties, BENTOCARPET is recommended for the following main applications:

• LANDFILLS

BENTOCAPRET is an excellent choice for the construction and remediation of bottom and cover sealing layers for different types of landfills.

• TRAFFIC INFRASTRUCTURE

BENTOCARPET is extremely suitable for the construction of road and rail infrastructure, airport surfaces and similar areas for transport infrastructure. With its exceptional hydraulic and mechanical properties, BENTOCARPET prevents migration of fluids through embankments, protects their stability and effectively prevents contaminated fluids from entering the surrounding soil, including deeper soil layers, protecting thus groundwater from pollution.

• HYDROTECHNICAL FACILITIES

BENTOCARPET is very suitable for the construction and management of embankments, canals, river waterways, surface reservoirs, artificial lakes, ponds, swimming pools etc.

• SECONDARY CONTAINMENT SYSTEMS

BENTOCARPET is extremely suitable for the construction and protection of chemical storages, various types of tanks (for fuel, oil and other hazardous waste), waste treatment/destruction facilities, liquid waste underground tanks, transshipment stations and similar, where BENTOCARPET is used as an effective secondary barrier that prevents the leakage of harmful substances into surrounding soil and groundwater.

BENTOCARPET was tested and certified by the Slovenian National Building and Civil Engineering Institute (CERTIFICATE-ZAG), after which we obtained the right to apply CE marking and issue the Declaration of Conformity in accordance with the EU standards regulating the application of bentonite mats (GCL).
