Thickness Options & Deployment Formats
LLDPE is available from 20 to 80 mil with multiple deployment formats — including tape-weldable quick-deploy panels for urgent jobs that can't wait for welding crews.
| Thickness | Panel Format | Weld Method | Best For |
|---|---|---|---|
| 20 mil | 20'×100' panels | Tape weld | Urgent / emergency jobs, quick deployment without welding crews |
| 40 mil | Custom prefab panels available | Extrusion + wedge weld | Standard industrial containment, irrigation ponds, lagoons |
| 60 mil | Custom prefab panels available | Extrusion + wedge weld | Heavy-duty containment, mining, aggressive environments |
| 80 mil | Custom as required | Extrusion weld | Maximum duty, high-stress applications, aggressive subgrades |
Emergency / Urgent Deployment
LLDPE 20 mil panels (20'×100') can be deployed and tape-welded immediately without specialized welding crews. Ideal for emergency containment, spill response, or urgent project starts while welded panels are being fabricated.

LLDPE vs. HDPE — Key Differences
Both are polyethylene geomembranes, but their properties suit different applications. Use this guide to choose the right material.
| Property | LLDPE | HDPE |
|---|---|---|
| Flexibility | Rubber-like — folds without damage | Less flexible, can crack when folded |
| Low Temp Performance | Outstanding cold resistance | Good, but can become brittle |
| Chemical Resistance | Good — broad compatibility | Excellent — widest range |
| Weld Methods | 40/60 mil: extrusion + wedge | Hot wedge + extrusion |
| Thickness Range | 20–80 mil | 20–120 mil |
| Quick Deploy Format | 20 mil tape-weld panels | Not available |
| UV Stability | UV-stable, no cover required | UV-stable, no cover required |
