PYRAWALL® Engineered Wrap-Faced Vegetated Solution

Highlights

• Superior UV resistance
• Provides superior material connection and system performance
• Durable, permeable and vegetated wall face for long-term performance and aesthetics

General Information

Soil reinforcement using sheets of embedded inclusions, such as steel-wire grids, woven geotextile fabrics, and polymeric geogrids, has significantly advanced geotechnical design and construction practices in the earthwork industry over the past 40 years. Installing planar, horizontal reinforcing elements in a constrained, compacted soil fill is the basis for constructing Mechanically Stabilized Earth (MSE) structures that include steepened slopes, known as Reinforced Soil Slopes (RSS), and near-vertical retaining walls.

In recent years, as site conditions allow, project designers have sought vegetated facing on these structures rather than traditional hardscape systems (i.e., concrete panels, modular blocks, shotcrete, or rock filled wire-frame units). In response, new patented technology has been developed to provide a vegetated facing option using PYRAMAT® 75, a pyramidalwoven, High-Performance Turf Reinforcement Mat (HPTRM), in conjunction with fiber-composite internal braces.

Product Information

PYRAWALL® is an engineered wrap-face vegetated solution for constructing reinforced-earth walls and steepened slopes. The system consists of PYRAMAT® 75 High Performance Turf Reinforcement Mat (HPTRM) and fiber-composite internal bracing. Featuring flexible setback and alignment, PYRAWALL®  can be customized to unique site conditions and geometrics.

The internal braces are designed to integrate with PYRAMAT 75 HPTRM and provide internal structure during
construction to facilitate placing and backfilling of PYRAWALL. The bracing members are designed to interlace
through PYRAMAT 75 HPTRM resulting in superior material connection and system performance throughout the
project’s design life.

How it works:

Benefits and Features of PYRAWALL®

• Interlaced bracing provides superior material connection and system performance
• Produces reinforced soil mass to resist lateral earth pressures and provides immediate erosion protection upon installation
• Is a Vegetated Best Management Practice Solution for NPDES Storm Water Compliance
• Superior UV resistance for up to 75 years of design life
• Eliminates the need for temporary metal bracing or removable forms to improve installation efficiency
• Flexibility of product allows for curves to be incorporated along the wall or slope alignment
• Provides durable, permeable and vegetated wall face for long-term performance and aesthetics
• Ideal for coastal climates because the components are environmentally inert and not susceptible to corrosion
• On-site soil can be used for infill eliminating the cost and carbon footprint of importing soil
• System is easily transported making it ideal for sites that are difficult to access
• If walls/slope are higher than seven feet requiring geogrid extensions, then PYRAWALL  serves as secondary reinforcement to redistribute potential high facing loads
• Patented triolobal X3® Fiber Technology helps lock in seeds and promote rapid root mass development
• Available in Green or Tan

Applications

• Wrapped-face Mechanically Stabilized Earth (MSE) structures
• Reinforced Soil Slopes (RSS)
