Sitting at 5,312 feet above sea level in the high desert, Albuquerque sees less than 10 inches of annual rainfall. Yet when it comes—or when we line ponds, landfills, and stormwater basins—the local soils demand a precise geomembrane specification. The arid climate produces high-plasticity clays and silty sands that shift with moisture changes. We pair our geomembrane work with a calicatas exploratorias to verify subgrade uniformity, then apply clasificacion de suelos to classify the foundation. This ensures the liner sits on a stable base.
In Albuquerque's high-desert soils, a 60-mil textured HDPE liner with proper UV stabilization cuts long-term leakage risk by more than half.
Methodology and scope
- Thickness selection per GM13 or GM17 standards (60-mil HDPE is typical)
- Tensile strength and elongation at yield per ASTM D6693
- Seam shear and peel adhesion testing per ASTM D6392
Local considerations
Compare the West Mesa basalt flows with the alluvial fans along the Sandia foothills: the subgrade conditions could not be more different. On the mesa, sharp basalt fragments can puncture an inadequately specified geomembrane within months. In the foothills, silty sands with low plasticity may settle unevenly, creating wrinkles and stress concentrations. We have seen projects fail because the geomembrane specification did not account for these local contrasts. A site-specific subgrade evaluation and proper geotextile cushion layer are non-negotiable in Albuquerque.
Applicable standards
GRI-GM13: Standard Specification for HDPE Geomembranes, ASTM D6693-19: Tensile Properties of Geomembranes, ASTM D6392-20: Seam Strength of Geomembranes, ASTM D4833-07: Puncture Resistance of Geomembranes, ASTM D1603-12: Carbon Black Content in Olefin Plastics
Associated technical services
Subgrade evaluation and soil classification
ASTM D2487 classification, compaction testing, and moisture-density analysis to ensure a smooth and stable foundation for the liner.
Geomembrane selection and thickness design
Seam testing and quality control
Non-destructive air-pressure testing (ASTM D5820) and destructive shear/peel tests (ASTM D6392) to verify field seam integrity.

Frequently asked questions
What is the typical cost range for a geomembrane specification study in Albuquerque?
For a standard containment project (1–5 acres), our specification work—including subgrade evaluation, material selection, and seam testing—ranges between US$660 and US$1,610. Larger sites or chemically aggressive applications may increase the scope.
Which ASTM standards apply to geomembrane specification in Albuquerque?
The primary standards are GRI-GM13 for HDPE geomembranes, ASTM D6693 for tensile testing, ASTM D6392 for seam integrity, and ASTM D4833 for puncture resistance. For carbon black content we follow ASTM D1603.
How long does a geomembrane specification study take?
A typical study takes 5 to 10 business days. This includes field work (subgrade evaluation and soil sampling), laboratory testing, and a final report with material recommendations and seam testing protocols.
Do I need a geotextile cushion under the geomembrane in Albuquerque?
Yes, especially on the West Mesa where angular basalt fragments are common. A 16-oz non-woven geotextile cushion protects the geomembrane from puncture and extends its service life significantly.
