Waterproof Membrane Geosynthetic Clay Liner

Geosynthetic Clay Liner is a new environment-friendly impermeable material. It is commonly used in artificial lakes and landscape pools. It is easy to install and requires less construction work. It is also resistant to various weather conditions.

Traditional GCLs consist of a layer of sodium bentonite sandwiched between two geotextiles or glued to a geomembrane. They are also less susceptible to differential settlement and desiccation-rewetting cycles than compacted clay liners.

Cost

The cost of Geosynthetic Clay Liner varies according to the brand, type, specification and model. The price is also influenced by the sales market, geographical location and other factors. Therefore, it is important to carry out a thorough control and comparison in all aspects before choosing and purchasing. The swellable sodium bentonite in GCLs provides superior waterproofing properties and can be installed on site without the need for a concrete mud slab. It is also able to withstand a wide range of weather conditions, including rain, sleet, snow and frost.

GCLs are comprised of a layer of high-swelling bentonite clay that is bonded to the inner surface of a non-woven geotextile. The bentonite absorbs and retains water, forming a uniformly dense colloidal waterproof layer that prevents the penetration of moisture. GCLs can be used in landfill, waste pond, and tailings landfill projects.

These waterproofing materials are available in a variety of thicknesses. They can be bonded to smooth or textured geomembranes. They are ideal for use in areas with fixed structures, such as slurry walls or auger cast retention systems. The swelling action of the bentonite clay self-seals small cracks caused by ground settlement or concrete shrinkage. This can help reduce the cost of sealing with adhesives.

The bentonite in GCLs is a natural, inorganic raw Waterproof Membrane Geosynthetic Clay Liner material that has excellent environmental performance. It is resistant to chemical corrosion and has a long service life. It is also safe for the environment and human beings.

Durability

Sodium bentonite is a natural, inorganic material that has a strong affinity for water. When hydrated, it expands to 15 times its original volume, providing the ability to seal around penetrations and self-heal punctures and seams. Additionally, it has better hydraulic performance than several feet of compacted clay.

GCLs are used for landfill and pond construction, as well as anti-seepage engineering in civil buildings and underground waterproofing of tanks and pipes. They are also a popular choice for concrete foundations. They help to protect the concrete structure from groundwater and prevent deterioration, which leads to cracking and shrinkage. The use of these materials can save both money and time, as they eliminate the need to build a basement beneath a concrete foundation.

Water penetration can cause major problems in a building, including foul odours, discolouration of walls and plaster, and bubbling paint. It can even cause structural damage to the building, leading to cracked bricks and blocks. In addition, moisture in concrete can cause severe damage to concrete floors and walls, and this can lead to the formation of mold, mildew, and fungi.

The durability of GCLs can be improved by ensuring that the proper amount of bentonite clay has been added to the final product. This can be done by testing the peel strength of the GCL and its anti-hydrostatic pressure resistance. In addition, it is important to ensure that the thickness of the GCL is correct.

Appearance

Geosynthetic clay liner, also known as GCL or bentonite blankets, are made of two geotextile layers encapsulating a layer of sodium bentonite. The bentonite is the key component of the mat, and it swells when it comes into contact with water to create an impermeable barrier. The material is often used in landfill and tailings landfill projects. It has excellent impermeability and is easy to install. It is also a cost-effective alternative to clay liners and is highly resistant to UV radiation.

Geosynthetic clay liners are also very durable and require little maintenance. They can be installed in any weather and can be laid on uncured concrete, making them ideal for waterproofing basements and horizontal foundation surfaces. In addition, the natural swelling action of the bentonite clay can self-seal small concrete cracks caused by ground settlement or seismic activity.

The GCL mat has good tensile and shear strength and can withstand a 0.5 Mpa hydrostatic pressure test. It is a non-toxic and non-corrosive product, which makes it an ideal choice for use in sensitive areas. It is a great alternative to other types of waterproofing, including polymer membranes and vinyl liners. In addition, the GCL can be easily cut to fit a specific area. The laying process is quick and simple, and the GCL mat can be overlapped for maximum protection.

Installation

The main function of a Geosynthetic Clay Liner is to serve as a hydraulic barrier to water. It is also used to line landfills, waste ponds, and other areas where water can leak from pipes or tanks. It is made up of a geotextile or geomembrane sandwiched between a layer of sodium bentonite. The bentonite swells when it meets water, creating a waterproof barrier.

The GCLs are also known by various names including “clay blankets”, “bentonite mats”, and “prefabricated bentonite clay blankets”. Regardless non woven geotextile suppliers of the name, they are used to line landfills or other sites where there is an environmental risk. They are a cost-effective alternative to conventional liner materials.

Unlike compacted clay liners, GCLs are more resistant to varying weather conditions and less likely to be impacted by freeze-thaw or desiccation-rewetting cycles. This allows them to maintain their performance for a longer period of time than traditional liners, reducing the need for frequent replacements.

GCLs are also highly durable and require little maintenance. They are easy to install and provide a permanent solution for seepage problems. They can be used in many applications, including residential garbage landfills, underground parking lots, roof gardens, and reservoirs. These geosynthetic materials are especially useful for anti-seepage construction in artificial lakes, ponds, and wastewater treatment plants. They can even be used in petrochemical plants and chemical storage yards.
