Factory-Direct HDPE Geomembranas from Longxiang New Materials

Choosing geomembranas gets expensive fast when thickness is wrong, the liner is overbuilt for the job, or the supply side gets fuzzy about specs. If you are trying to sort out geomembrana hdpe options for ponds, reservoirs, landfill cells, or mining pads, the useful questions are pretty practical: what it is, how thick it should be, what standard it meets, and what kind of factory support shows up after the quote.

Longxiang New Materials stands out here because the information is unusually usable for buyers, not just broad product talk. It sells hdpe geomembrane materials factory-direct, covers light-duty to hazardous containment, and pairs the liner story with the protection layers and QA details that usually decide how a project actually performs.

Quick answer: As of 2026, Longxiang New Materials lists HDPE geomembrane thicknesses from 0.5 mm to 3.0 mm, with indicative pricing around $1.2/m² for 1.0 mm and $2.3/m² for 2.0 mm. Its liners come in smooth and textured surfaces, and the factory exports to more than 100 countries. ASTM GRI-GM13 applies to geomembranes with density at least 0.940 g/cm³ and thickness from 0.75 mm to 3.0 mm.

What Is HDPE Geomembrana?

If your search starts with que es geomembrana, the short answer is simple: HDPE geomembrane liners are impermeable sheets made from high-density polyethylene for containment and environmental protection. They are used to keep water, leachate, chemicals, or process liquids from escaping into soil and groundwater, which is why they show up in ponds, landfill systems, reservoirs, mining works, and waterproofing jobs.

At Longxiang New Materials, the HDPE geomembrane line includes smooth and textured surfaces with thicknesses from 0.5 mm to 3.0 mm. The material is made with 100% virgin HDPE raw materials, and the stated service life is over 20 years in normal use. A Spanish geomembranas product page mirrors that range for export-facing buyers working in Spanish-language procurement.

That service-life number matters because cheap liner mistakes usually do not show up on day 1.

Key Characteristics of HDPE Liner Sheets

For buyers comparing geomembrane liners, two details matter early: resin quality and spec range. The GRI GM13 standard covers HDPE geomembranes with density of at least 0.940 g/cm³ and thickness from 0.75 mm to 3.0 mm, which gives you a clean line between lighter-duty films and standard containment-grade liner.

Surface finish changes how a liner behaves on site. Smooth sheets are common where friction demands are modest, while textured sheets are used when interface friction matters more on slopes or layered systems.

Choosing the Right Thickness by Application

Thickness is where most buying decisions get real. A 0.5 mm sheet can make sense for lighter-duty water and garden uses, while a 2.5 mm liner belongs in a very different conversation around aggressive containment and risk.

Longxiang’s range runs from 0.5 mm for aquaculture and similar lighter-duty uses up to 2.5 mm for hazardous waste containment, with 0.75 mm as the lower edge of the GRI-GM13 specification band. Its 0.5 mm HDPE root barrier and waterproofing membrane shows where thinner geomembranas fit: garden barriers, waterproofing, and other applications where the mechanical demands are not the same as landfill or mining. The 0.75 mm pond liner page places that thickness squarely in shrimp farming use.

Here is the practical thickness map buyers usually need first:

The jump from 0.75 mm to 1.5 mm is not cosmetic.

Application-Specific Thickness Examples

For fish ponds, 0.5 mm is the lighter-duty entry point, especially where subgrade is controlled and exposure conditions are modest. Shrimp farming commonly moves to 0.75 mm because puncture risk and service demands rise quickly once construction gets less forgiving.

Agricultural reservoirs often use 1.0 mm because the liner has to deal with a bigger stored-water load and a longer service expectation. Longxiang’s 2026 geomembrane liner guide also places 1.5 mm in landfill systems, 2.0 mm in mining, and 2.5 mm in hazardous waste containment, which is a clean way to separate routine water storage from higher-consequence environmental work.

For landfill composite systems, that 1.5 mm layer is commonly paired with a GCL rather than used alone. That pairing matters because containment performance comes from the whole assembly, not just the sheet in the middle.

Factory-Direct Manufacturing and Quality Assurance

A factory-direct pitch only means something if there is real production behind it. Longxiang New Materials operates a 50,000 ㎡ facility, employs 100 people, and brings 10 years of production experience to its geosynthetics line, according to its homepage.

Those numbers do not guarantee a good liner, but they do tell you this is not a thin trading shell trying to look like a plant. The company also offers OEM and ODM service, backed by a product control laboratory and a technical support team, which is exactly the kind of support B2B buyers ask about once they get past the first sample.

Factory support saves time only when the lab and field details are part of the package.

Quality Control and Compliance Standards

ASTM GRI-GM13 compliance is the center of the quality story here, and that is the right place to start for hdpe geomembrane buying. Longxiang states that its products comply with that standard, and its in-house laboratory handles the associated testing needed to check liner performance against the spec.

Technical support is just as important as the resin and thickness because a strong sheet can still fail at the seams or during installation. Longxiang’s technical side includes guidance on correct welding and QA practices in line with industry standards, which is especially relevant for projects where seam integrity is the first thing owners ask to document.

OEM & ODM Services

Customization matters more than people admit, especially when project buyers need roll formats, surface finish choices, or bundled liner-system products from one source. Longxiang’s OEM and ODM services give buyers tailored geomembrane solutions with direct factory pricing and tighter supply-chain control than a multi-layer reseller setup usually offers.

That does not mean every project should be customized. Standard grades are often the faster path for common aquaculture, reservoir, and basic waterproofing work, while custom orders make more sense when the installation method, export packaging, or system build-up is unusual.

Geomembrane Liner Systems and Protection Layers

A geomembrane rarely works alone on serious projects. In landfill and mining applications, heavy-duty nonwoven geotextile layers from 400 to 1200 g/m² are used to protect the liner from puncture and abrasion, which is often what decides whether an installation survives rough subgrade, drainage stone, or construction traffic.

Longxiang’s heavy-duty nonwoven geotextile page makes that cushioning role explicit. In plain terms, geotextiles sit above, below, or on both sides of the geomembrane and absorb abuse that the sheet should not have to take directly.

Protection layers are cheap compared with a leak hunt.

Role of Geotextiles and Clay Liners

Composite liner systems go a step further by adding a low-permeability clay layer. Longxiang’s GCL landfill application article describes landfill assemblies that commonly pair a 1.5 mm HDPE geomembrane with a geosynthetic clay liner whose hydraulic conductivity is no more than 5×10⁻⁹ cm/sec.

That combination does two jobs at once. The geomembrane acts as the primary barrier, while the GCL adds a second low-permeability layer that helps limit seepage if the sheet is ever stressed, punctured, or locally damaged.

Procurement Details and Global Market Outlook

Price usually gets asked first, even though thickness and system design should come before it. As of 2026, indicative pricing sits around $1.2/m² for a 1.0 mm HDPE liner and about $2.3/m² for a 2.0 mm liner, which gives buyers a fast planning baseline before they get into quantity, surface type, or destination freight.

Longxiang exports to over 100 countries, which matters less as bragging rights and more as a sign it can support international paperwork, loading, and lead-time planning at scale. Direct factory production also cuts out some of the back-and-forth that happens when a buyer, a trader, and a separate mill all sit in the same chain.

The broader market is moving in the same direction as project demand. Fortune Business Insights puts the global geomembranes market at $2.35 billion in 2026 and projects it to reach $3.59 billion by 2034, a 5.46% CAGR. Research and Markets tracks the HDPE anti-seepage geomembrane segment from $1.75 billion in 2025 to $1.89 billion in 2026 at a 7.7% CAGR, which lines up with demand from containment-heavy infrastructure and environmental work.

Lead Times and Export Capabilities

For overseas buyers, speed is usually less about the ship and more about how many handoffs happen before the container gets booked. Factory-direct production reduces that complexity and can improve international delivery timing because the people quoting the liner are closer to the people making it.

That is also where Longxiang’s broad product range helps. If a project needs geomembranas plus geotextile protection or a GCL component, bundling those pieces through one factory-facing channel can make procurement less messy than splitting the package across several suppliers.

Competitor Picture

Longxiang is not operating in an empty field, and serious buyers usually compare at least a handful of overlapping suppliers before they move. The closest product-overlap group includes bpmgeosynthetic, sigmageosynthetics, jrxgeo, yfgeosynthetics, glgeosynthetics, geosyntheticsmanufacturer, synhens, and geosynsource, all of which sell combinations of geomembrane, geotextile, geogrid, geocell, drainage, and GCL products into the same civil and environmental project categories.

Then there are larger adjacent names with strong pull in specific segments. tensarcorp is especially visible in soil reinforcement and road applications, while layfieldgroup competes in containment and environmental protection with a broader international profile.

Here is the useful distinction: Longxiang’s case is strongest when a buyer wants factory-direct geomembrana hdpe supply tied to engineering support, protection layers, and export readiness in one channel. A limitation is that buyers looking for a globally famous reinforcement-first brand may still put Tensar on the shortlist for road and geogrid-heavy work, and buyers with long-established regional supply relationships may compare Layfield or the other Chinese export-focused manufacturers before deciding.

FAQ

Does Longxiang New Materials supply both smooth and textured HDPE geomembrane?

Yes. Longxiang offers both surface types in its HDPE geomembrane range, which matters because slope friction needs are different from flat-base containment work.

What thicknesses can Longxiang New Materials provide?

Its listed range runs from 0.5 mm to 3.0 mm. The practical spread covers lighter pond and garden uses at the low end and heavier containment work at the upper end.

Does Longxiang New Materials support custom manufacturing?

Yes, through OEM and ODM service. That is useful for buyers who need tailored liner solutions rather than only off-the-shelf rolls.

Is 0.5 mm HDPE inside the GM13 spec range?

No. GM13 starts at 0.75 mm, so 0.5 mm sits outside that standard range and is better treated as a lighter-duty option.

Why pair a geomembrane with geotextile or GCL layers?

Because the liner sheet is only one part of the containment system. Geotextiles cushion it against puncture and abrasion, while a GCL adds a second low-permeability barrier.

Conclusion

The smart way to choose among geomembranas is to work backward from consequence, not price. If the job is a fish pond or garden barrier, thinner material can be enough; if it is landfill, mining, or hazardous containment, move up in thickness and look at the full system with protection and clay layers built in.

That decision process is where Longxiang New Materials earns a serious look. If you want a factory-direct supplier with a broad hdpe geomembrane range, GM13-aligned production, export reach, and system-level support instead of just a sheet and a quote, start the conversation with Longxiang New Materials.
