Landfill Bentonite Waterproof Blanket
Landfill Bentonite Waterproof Blanket is a kind of geosynthetics used in artificial lake waterscape, landfill, underground garage, building roof garden, oil depot and chemical pile yard. It is a soil impervious mat filled with high swelling sodium bentonite by needle embroidering method.
The bentonite is highly swell after absorbing water, and the formed gel impermeable body has strong anti-seepage performance and low water conductivity.
Product Application
Sodium bentonite waterproof blanket is a new type of environmentally friendly ecological Landfill Bentonite Waterproof Blanket composite seepage control materials. Its main components are sodium bentonite and plastic woven cloth. The bentonite is pressed and fixed through special needle punching process, which makes the product easy to construct. The bentonite waterproof blanket is especially suitable for landfill foundation treatment and capping, building roof garden, underground garage construction, water tank, oil depots, chemical pile yard and other anti-seepage projects.
The swellable bentonite clay waterproofing system, also known as VOLTEX, is based on the unique, high-swelling properties of sodium bentonite. This natural earth from volcanic origin has the ability to swell many times its dry volume when it is contacted with water. When confined, it forms a dense, impenetrable gel that locks out water and vapour.
VOLTEX is manufactured by CETCO’s Building Materials, which specialises in the supply of Geosynthetic Waterproofing Products. Millions of square metres have been successfully installed worldwide using the CETCO patented VOLCLAY technology. The swellable bentonite works by encapsulating concrete and soil to form an impermeable barrier. It can even self-seal small cracks caused by ground settlement, seismic activity or concrete shrinkage. Its low permeability allows it to be used under backfill and can even be placed directly on top of a poured in place concrete structure. This reduces the need for expensive grouting and can speed up project completion.
Production Process
GCL is a factory-manufactured hydraulic barrier that incorporates bentonite, a type of mineral clay that swells when it gets wet. It consists of two layers of geosynthetic textiles, typically a woven and a non-woven, needle-punched together to form a composite that encloses a layer of sodium bentonite. The bentonite is then subject to a proprietary heat treating process that permanently locks it into the fabrics, producing a very strong and durable bentonite liner.
EUROBENT’s bentonite liners are an effective solution for projects requiring high seepage prevention and construction flexibility. This is because the bentonite is incorporated into a matrix of stronger geotextiles, which significantly increases internal shear strength and resistance to creep. In addition, the bentonite lining has been subjected to a series of tests and is certified by an independent third party laboratory.
The test results demonstrate the superior performance of EUROBENT C compared to other bentonite products. This is due to a unique manufacturing process that ensures maximum swelling and rapid water absorption, and to an improved material composition.
Sodium bentonite composite waterproof blanket is a new type of impermeable geosynthetic materials. It mainly uses composite plastic flat silk geotextile and non-woven fabric, filled with high expansion sodium bentonite, to form a high density diaphragm in the wet state and has excellent impermeability performance. It is widely used in artificial lake water scenery, refuse landfill, embankment, underground garage, pond, oil depot and chemical stockyard to prevent infiltration.
Quality Control
The swellability of the raw material, the mixing process, and the equipment used for production all play an important role in the quality of the finished product. It is necessary to ensure that the product has a high degree of quality before it is shipped out. To achieve this, the raw material is subject to strict quality control procedures. For example, the tensile and peel strength tests must be passed before the product is sold.
The bentonite waterproof blanket is made up of two geosynthetic materials layers and a salt-resistant bentonite layer fixed between the two. The salt-resistant bentonite layer includes a polymer with certain adhesion and bentonite particles that are uniformly blended. The polymer has a strong binding effect Geosynthetic clay liner on the bentonite particles, which makes them connect with each other and reduces the permeability coefficient.
The sodium bentonite composite waterproof blanket (GCL) is a new type of geosynthetic liner. It is made up of graded sodium bentonite particles and corresponding additives mixed as raw materials and fixed by needle punching processing equipment to the geotextiles and plastic woven fabrics. It has all the characteristics of geotextiles and excellent waterproof (permeability) properties. It is mainly applied in the construction of artificial lakes, waste landfills, underground garages, ponds, oil depots and chemicals yards. It is suitable for a variety of environmental engineering projects and can be laid in negative temperatures.
Inspection Items
The BGCL can be placed in landfills to prevent hazardous materials from entering soil and water, and it also provides a barrier against the spread of fire. In addition, it can be used in ponds and hydrotests to keep water from seeping into the ground. Unlike other types of waterproofing materials, BGCL is not affected by temperature and will not become brittle in cold climates.
Sodium bentonite composite waterproof blanket is a kind of geosynthetic clay liner that is filled with high expansion sodium bentonite in special composite geotextiles and non-woven fabric. Sodium bentonite expands in a hydraulic state, forming a high-density diaphragm that has excellent impermeability performance.
It is easy to operate, load and install. Moreover, it has excellent construction convenience and short construction period. In addition, it is resistant to leakage and has good stability. The BGCL is suitable for artificial lake water, landfill, underground garage, roof garden, pool, oil depot and chemicals yard.
