Geosynthetics Clay Liner

What Is Geosynthetic Clay Liner?

Geosynthetic Clay Liners are simple factory-made waterproof barriers. They pack sodium bentonite between soft geotextile layers. When wet, the bentonite actually puffs up. This creates a super tight seal for landfills, artificial lakes, deep basements, and safe containment projects.

A Waterproof Needle Punched Bentonite Blanket is way thinner and easier to install than heavy packed clay. You just spread the rolls on flat dirt, overlap the edges, seal the joints, and safely cover it.

Folks mostly use this for Geosynthetic Clay Liners for Landfill Project jobs, artificial lakes, wastewater ponds, basement sealing, and composite liner systems. Buyers must check the bentonite mass, roll width, tensile strength, peel strength, overlap rules, and safe storage conditions.

CHANGFENG supplies the gcl Bentonite Geosynthetic Clay Liner. We happily provide custom project labels, batch records, test documents, and strong export packing for busy contractors and geosynthetic distributors.

Product Features and Benefits

1. Sodium Bentonite Barrier

The bentonite core swells when hydrated and helps create a low-permeability waterproof barrier.

2. Needle Punched Structure

Needle punching locks geotextile layers and bentonite together for better handling and installation stability.

3. Landfill and Pond Use

The liner is suitable for landfill project work, artificial lakes, ponds, reservoirs, and containment zones.

4. Compact Roll Supply

Rolls are easier to ship and install than large volumes of compacted clay.

5. Custom Bentonite Mass

Sodium Base 5kg 6kg and project-based grades can be supplied.

6. Testing Document Support

CHANGFENG can prepare roll labels, batch records, test documents, and loading photos.

7. Project Supply Support

Bentonite mass, roll width, roll length, overlap design, packing, labels, test documents, and OEM/ODM support can be arranged for Geosynthetic Clay Liners orders.

Application Scenarios

1. Landfill Base and Cover Systems

Builders definitely use Geosynthetic Clay Liners for Landfill Project jobs. Installed with proper covers and drains, they easily stop nasty leachate leaks.

2. Artificial Lakes and Ponds

Making artificial lakes or garden ponds? Just lay GCL right under your dirt or geomembrane to form a perfectly tight seal.

3. Basement Waterproofing

People also wrap Bentonite Waterproof Blanket rolls around deep basements. The bentonite actually puffs up when wet, completely blocking the water.

4. Reservoir and Canal Sealing

For huge water projects, GCL works beautifully. It builds a solid wall for heavy reservoirs, long canals, and big water setups.

5. Waste and Industrial Containment

Finally, this liner safely hugs trash dumps and dirty sludge ponds. Just make sure your site designer checks those harsh chemicals first!

Quality Control

CHANGFENG checks GCL production by bentonite mass, geotextile condition, needle punching uniformity, roll width, roll length, edge condition, and surface appearance. Permeability, peel strength, and mass per unit area can be tested according to project requirements.

For landfill or containment projects, roll labels, batch records, packing photos, loading photos, and test documents can be prepared. Third-party inspection or special sampling should be confirmed before production.

Packing and Delivery

Geosynthetic Clay Liners are supplied in rolls with protective wrapping. Rolls can be loaded by container, pallet, or project sequence. Labels can show product name, bentonite mass, roll width, roll length, batch number, and order information for easier site management.

FAQ

Q1: What are Geosynthetic Clay Liners used for?

A: We use them to block leaks in landfills, artificial lakes, ponds, basements, reservoirs, and containment jobs.

Q2: What is inside a Bentonite Geosynthetic Clay Liner?

A: It packs sodium bentonite tightly between geotextile layers. Factories lock it together by needle punching.

Q3: Why is sodium bentonite used?

A: When sodium bentonite gets wet, it puffs up. This easily builds a super tight sealing layer.

Q4: Can GCL replace compacted clay?

A: Yes, it often replaces heavy compacted clay. But, your project engineer makes the final call.

Q5: What bentonite mass is available?

A: We sell popular Sodium Base 5kg 6kg waterproof needle punched options. Custom grades work too.

Q6: What information is needed for quotation?

A: Share the bentonite mass, roll width, length, and amount. Also tell us your job, destination port, and test needs.

Q7: How should it be installed?

A: Smooth the dirt, overlap the rolls, seal the edges, and safely cover the liner per your plan.
