Abstract
Described herein are systems and methods for forming an improved Drainliner Max with improved load bearing capability in the range of 500-15,000 or 23 to 720 kPA via improved stud placement and improved height/diameter dimensions to provide a much improved product that vastly outperforms existing systems.
Claims17
An improved geomembrane comprising:
- a substrate;
- at least two studs on the substrate;
- a stud density defined on the substrate via placement of the at least two studs to provide a three-dimensional contour on the substrate;
- and
- wherein the stud density allows the substrate to provide a support weight of 1,500 to pounds per square foot or 23 to 720 kPa.
2 more elements
A method for forming an improved geomembrane comprising:
- extruding a molten polymer onto a calendaring roller gap;
- pressing the molten polymer into at least two stud cavities defined on a roller;
- cooling the molten polymer to solidify the molten polymer into a substrate and to form at least one two studs on the substrate wherein the studs conform to a shape of the at least two stud cavities defined on the roller;
- defining a stud density on the substrate via placement of the at least two studs to provide a three-dimensional contour on the substrate;
- and
- forming the stud density so the substrate has a support weight of 1,500 to 15,000 pounds per square foot or 23 to 720 kPa.
