" />Puncture resistance measures the liner's ability to resist concentrated loads from stones and sharp subgrade material.
Test Method
A steel plunger or CBR cone presses through the clamped specimen at a constant rate. The maximum force at penetration is recorded. Higher puncture resistance reduces damage during installation and service.
Why It Matters
This property is critical when the subgrade contains angular rock. Geotextile cushion further helps. See our product page or contact us.
