Superior Lay-Flat Quality & Easy Fabrication
To ensure uniformity and reduce risks during installation, a geomembrane needs to be truly square (no bowing) and flat (no wrinkles). XTRM PLY® PVC geomembranes excel in both areas, allowing you to achieve straight seams without the hassles of wrinkles or creasing, which are common challenges with inherently bowed or wrinkled factory-delivered products.
- Lay-flat design reduces installation time.
- Consistent flatness minimizes potential leak points.
- Uniform squareness enhances fabrication efficiency.

PVC Geomembranes vs. Other Types
Not all geomembrane materials perform equally across applications. The right choice depends on flexibility requirements, installation conditions, seaming method, and long-term exposure. Here’s how PVC compares to the most common alternatives.
| Property | PVC | HDPE | EPDM |
|---|---|---|---|
| Flexibility | High | Low | Medium |
| Weldability | Heat, RF, adhesive, wedge | Heat, extrusion | Primarily adhesive; thermal options are limited |
| Lay-flat quality | Superior | Prone to wrinkling | Moderate |
| Chemical resistance | High | Very high | Moderate |
| Repairability | Easy | Requires specialized equipment | Moderate |
PVC vs. HDPE
HDPE geomembranes offer excellent chemical resistance and are widely used in landfill and mining applications. However, HDPE is a rigid material that is prone to wrinkling during installation, requiring more site preparation and skilled labor to achieve a proper fit. PVC’s higher flexibility allows it to conform to uneven subgrades with less effort, reducing installation time and the risk of stress points at seams.
PVC vs. EPDM
EPDM is a rubber-based membrane most commonly used in roofing and some pond lining applications. While it offers good UV resistance for exposed installations, EPDM seaming relies primarily on adhesive methods, with limited thermal welding options. This makes it less versatile than PVC in containment applications where seam integrity is critical. PVC geomembranes support heat, RF, adhesive, and wedge welding, giving fabricators more options to achieve stronger, more consistent seams across a wider range of project conditions.
Frequently Asked Questions About PVC Geomembranes
XTRM PLY® PVC geomembranes are available in 30, 40, and 60 mil thicknesses, covering a range of applications from pond lining to heavy-duty retention walls and industrial containment.
BABAA stands for the Build America, Buy America Act, which requires that iron, steel, manufactured products, and construction materials used in federally funded infrastructure projects be produced in the United States. XTRM PLY® PVC geomembranes are BABAA compliant, making them eligible for use in government and municipally funded projects subject to these requirements.
Yes. Every XTRM PLY® PVC geomembrane meets ASTM D7176 standards, which govern physical and mechanical property requirements for PVC geomembranes used in geotechnical and environmental applications.
XTRM PLY® is compatible with heat, RF, adhesive, and wedge welding, giving fabricators the flexibility to use the method best suited to their project and equipment.
XTRM PLY® PVC geomembranes are manufactured in the USA by Ronald Mark Associates and kept in stock for short lead times.
When installed correctly and protected from extreme exposure, they can last 20–50 years—a reliable option for long-term water containment.
A PVC geomembrane is an impermeable liner designed for water containment and seepage prevention in canals, reservoirs, ponds, and more. Its high flexibility and ease of installation make it ideal for diverse projects.
- Superior Layflat Properties: Minimizes wrinkles and ensures a secure fit.
- Wider Widths (76″ to 120″): Fewer seams save time and reduce leak risks.
- Exceptional Thickness (Up to 60 Mils): Enhanced puncture resistance for retention walls.
- Easy Handling: PVC’s pliability accommodates complex shapes without excessive folding.
- Contractor-Size Rolls: 200-foot rolls of 30-mil PVC simplify field fabrication.
- Greater Flexibility: Adapts to uneven surfaces, minimizing site prep.
- Reduced Seaming Needs: Fewer seams via wider sheets and factory-fabricated panels.
- Ease of Installation: Less specialized equipment required compared to stiffer materials.
XTRM PLY® was introduced in 2010 and has been a trusted spec in the RV market for over 15 years, manufactured under ISO 9001:2015 certified processes at Ronald Mark Associates’ US facilities.
Our wide-width geomembranes reduce seams and lie flat against prepared subgrades. Seams are secured using thermal or chemical fusion, significantly lowering wrinkles and air pockets. For retention walls, thicker 60-mil products offer optimal flexibility and strength.
XTRM PLY® PVC geomembranes are available in widths ranging from 76 to 120 inches, reducing seam requirements and fabrication time on large-scale projects.
