Eco-Friendly Geosynthetic Clay Liner for Landfill Base
Description:
The bentonite mat is an effective membrane that contributes to structural waterproofing. It has excellent mechanical properties thanks to the use of resistant geotextiles during the manufacturing process.
Our bentonite mat is designed to resist mechanical damage that appears on every construction site. Reinforced geotextiles, used in the manufacturing process, make the product durable and robust.
The product is a self-expanding geocomposite sheet, characterized by a high swelling capacity.
The Bentonite Geocomposite is a waterproofing product containing sodium bentonite, which is used to waterproof foundations, concrete structures and underground environments in general, which have contact with the ground and are at risk of water infiltration (cellars, garages, warehouses, vaults, underpasses , galleries).
Like the bentonite joint, which is usually used in synergy with this product, bentonite mats are applied when the concrete is poured, during construction.
The bentonite mat is composed of two layers of geotextile fabric sewn together, which enclose a uniform layer of natural sodium bentonite.
Advantages of Bentonite Mats
It is an excellent active waterproofing of underground structures and underground parts of buildings
The main advantage of the bentonite mat is its extraordinary ease of installation. The cover can be applied to dry and wet surfaces in different weather conditions. On vertical surfaces, the bentonite sheet can be nailed directly to the concrete
Does not require additional fixings on horizontal surfaces
The use of primers or special preparations is not required
It does not require the use of protective layers
The bentonite mat is supplied in rolls and is easily applied to the affected surfaces. It clings easily to surfaces, is resistant to tearing, and adapts easily even to complex geometries.
Application of Bentonite Mats
Our bentonite mats are efficient waterproofing and insulating materials, providing waterproofing to protect soils, subgrades and structures in many civil, geotechnical and environmental applications, including:
Tunnel linings
Landfill linings
Sealing of earthen reservoirs and dams
Sealing of pipelines, storage facilities for petroleum derivatives, etc…
Waterproofing of foundation and underground walls, bridge bases and other wall structures
Sealing of road and railway foundations in protected areas.
Bentonite mats also offer a cheaper and less intensive alternative to traditional clay barriers.
