PURPOSE & DESCRIPTION

Filtrexx ® Slope protection is a slope stabilization, erosion control, and vegetation establishment practice used on hill slopes to stabilize bare, disturbed, or erodable soils on and around construction activities. Slope protection is used for temporary and permanent erosion control and vegetation establishment applications. Slope protection is surface applied to a depth of 1.5 to 2 in (35-50mm) or 200-270 cubic yards/ac (385-513 cubic m/ha), and normally applied to hill slopes with pneumatic blower trucks/similar equipment. Filtrexx ® Support Practices, LockDown tm Netting and Tackifying agent, are used to increase the stabilization and erosion control capabilities of Slope protection. LockDown tm Netting is a single net erosion control blanket stapled to the slope prior to application of Slope protection. Tackifying agent is an all-natural polymer applied to the surface of the Slope protection to further reduce turbidity and suspended solids in runoff.

APPLICATION

Filtrexx ® Slope protection is used for slope stabilization, erosion control and vegetation establishment on disturbed, bare, or highly erodable soils during land disturbing and construction activities. Slope protection is typically used after fnal grading for temporary or permanent seeding applications. Custom seed mixes may be added to the Slope protection and applied directly to the slope. Non-seeded applications shall be considered a temporary form of erosion control. Slope

Slope Stabilization & Erosion Control Technology

protection can be used on slopes up to 2:1 without the use of additional soil stabilizers or support practices. Slopes greater than 2:1 require the use of LockDown tm Netting or Tackifying agent support practices. Slope protection should not be used in areas of concentrated runoff fow. Filtrexx ® Slope interruption may be used with Slope protection to reduce effective slope lengths, runoff velocity, and the potential for rill erosion. Filtrexx ® Support Practices tm can be used to increase the performance and area of acceptable application for Slope protection.

INSTALLATION

1. Slope protection used for slope stabilization, erosion control, and vegetation estab. shall meet Filtrexx ® Slope protection specifcations and use Filtrexx ® GrowingMedia tm .

2. Contractor is required to be a Filtrexx ® Certifed tm Installer as determined by Filtrexx ® International, LLC (440-926-8041 or visit website at www.fltrexx.com). Certifcation shall be considered current if appropriate identifcation is shown during time of bid or at time of application (current list can be found at www.fltrexx.com). Look for the Filtrexx ® Certifed tm Installer Seal.

3. Slope protection will be placed at locations indi- cated on plans as directed by the Engineer.

4. Slope protection shall be applied to 100% of the area where erosion control and vegetation is required.
