Construction started by installing more than 81,000 prefabricated vertical drains over 6.8 million linear feet. The vertical drains were installed around the perimeter of the landfill in the area of the foundation berm. Afterward, the berm was constructed on top of the PVDs then placing the very high-strength reinforcement geotextile with drainage sand. The 2 bottom layers of the reinforcement were critical for stability to the reinforced berm. The 2 layers consisted of TenCate Mirafi® PET geotextile. The geotextile was the highest strength ever manufactured for this kind of construction within the United States. The strength of the woven polyester geotextile was 1,170 kN/m (80,000 lb/ft).
The length of the installed 2 bottom layers of polyester geotextile was 140 feet long. The length was needed because of the very soft subgrade. Two additional long installments of high-strength Mirafi® PET were used at the mid-height of the berm for added stability. The rest of the berm was constructed using TenCate Miragrid® 20XT polyester geogrid. The embedded lengths of Miragrid® 20XT ranged from 20 to 80 feet. The berm was constructed with a face batter of 1 horizontal to 3 Vertical (1H: 3V), 72° from horizontal, so technically it was a wall. The face detail was made up of l-shaped wire baskets serving as a form for fill placement and TenCate Miramesh® GR wrapped around the face. Miramesh® GR is a small passage (2mm) grid material that was used as a secondary reinforcement and the facing wrap was used for stability as well as for erosion protection. The open characteristic of Miramesh® allowed for quick germination of vegetation through reinforcement. Local vegetation was used at the site and grew quickly at the face after construction. The berm was constructed up to 60 to 70 feet in height with a total length of around 8,700 feet or 1.6 miles. The entire face area of the berm was around 475,000 square feet. Well over 2 million cubic yards of fill was needed for the construction of the berm. The berm required over 80,000 square yards of Mirafi® PET, 670,000 square yards of Miragrid® 20XT, and 315,000 square yards of Miramesh® GR.
The uniaxial tensile plastic geogrid possesses exceptionally high tensile strength and tensile modulus. This plastic geogrid mesh is crafted from high-density polyethylene (HDPE) as the primary material, extruded into thin sheets, punched to form a regular mesh, and subsequently longitudinally stretched. It finds widespread applications in various fields, including dams, tunnels, docks, highways, railways, and construction projects.

Constructed from specially treated high-strength steel wire, combined with polyethylene (PE) or polypropylene (PP), and other additives, it undergoes extrusion to form a composite high-strength tensile strip with a rough embossed surface. The strips are then vertically and horizontally braided or sandwiched at specific intervals, and the intersection points are welded using specialized fusion welding technology (ultrasonic welding technology) for enhanced bonding. This geogrid membrane is primarily employed in soft soil foundation reinforcement, as well as in applications such as retaining walls, pavement anti-crack engineering for highways, railways, bridge abutments, approach roads, docks, dams, and slag dumps.
