The following describes parameters for the manufacture, supply, and installation of Poly-Flex Drainage Net and Geocomposites.

1.2 Qualifications

The drainage net manufacturer shall have successfully manufactured 5 million square feet of polyethylene drainage net.

1.3 Submittals

The Manufacturer shall provide the following information:

1. List of material properties.

2. Quality control certificate for the drainage net, geotextile, and geocomposite rolls, upon request.

2.1 Materials

2.1.1 Drainage Net

The drainate net shall be manufactured by extruding two sets of polyethylene strands to form a three dimensional structure to provide for planar flow. The drainage net shall be manufactured of polyethylene resin produced in the United States and compounded and manufactured specifically for the intended application. The natural polyethylene resin without the carbon black shall meet the following requirements:

Property		Test Method		Requirements
Density,g/cc		ASTM D 1505 or ASTM D 792		0.945 - 0.955
Melt Index,g/10 min.		ASTM D 1238 Condition E		< 1.0

The drainage net shall be supplied in rolls 14 feet wide, as manufactured by Poly-Flex, Inc. 2000 W. Marshall Dr., Grand Prairie, Texas 75051. Labels on each roll shall identify the thickness of the material, the width and length of the roll, lot and roll numbers, and name of the manufacturer. The drainage net rols shall meet the requirements in this specification.

2.1.2 Geotextile

The geotextile shall be a non-woven needle punched polyester or polyethylene fabric manufactured in the U.S. for the specific application. The geotextile rolls shall be a minimum of 15 feet wide and shall meet the requirements in this specification.

2.1.3 Geocomposite

The geocomposite shall consist of the Poly-Flex HDPE drainage net heat bonded to one layer or sandwiched between two layers of geotextiles to create a single-sided of double-sided geocomposite. The geocomposite shall be 13.5 feet wide. The geotextiles shall extend a minimum of 6 inches beyond the edges of drainage net on both sides of the geocomposite roll. The geotextile shall not be bonded to the drainage net within 6 inches from the edges of the rolls.

The Drainage Net shall be tested by its manufacturer once every 50,000 square feet for listed properties, except the transmissivity, which shall be tested once every 100,000 square feet.

The geotextile shall be tested by its manufacturer once every 100,000 square feet.

The geocomposite shall be tested by its manufacturer once every 100,000 square feet for the listed properties.

Any rolls not meeting the requirements of the specification shall be rejected. The manufacturer shall prepare a quality control report to be submitted to the project engineer upon request.
