DOT Highway & Roadway Dust Capping Revegetation Matrix
in Nevada
Arid alkaline soil and gravelly loam make subsoil stabilization incredibly difficult. You must spray drought-tolerant tackifiers and moisture-retaining mulches to stop the wind from blowing your seed away. This locks in the tiny amount of moisture available so your seed actually germinates.
Operational Constraints for DOT Highway Expansion
Highway expansions and road widenings expose massive, continuous steep slopes directly adjacent to active traffic. The constant wind shear from passing heavy commercial vehicles and earth-moving equipment vibration degrade weak agricultural tackifiers long before vegetation can establish. Furthermore, contractors must apply the matrix across extended linear distances, requiring a slurry that sprays efficiently from the cannon without cavitating the hydroseeder pump. You need an engineered binder that provides extreme shear resistance to protect the embankment, prevent subgrade failure, and keep the roadway clear of sediment runoff.
Meeting NDOT Standard Specifications Section 208 Specifications
OHRA GreenTack & ViscoLok anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by NDOT Standard Specifications Section 208. Its microplastic-free botanical hydrocolloid network forms a 3D matrix. It resists high-velocity storm runoff and keeps synthetic toxins out of the watershed.
The matrix prevents "fisheye" lumping inside your hydroseeder pump. This stops pump cavitation and reduces friction head loss. You maximize your tank's spray payload and eliminate constant agitation adjustments on the job site.

Field Troubleshooting Guide
| Field Symptom | Likely Cause | Immediate Job-Site Fix |
|---|---|---|
| Slurry Too Thick / Hard to Pump | Exceeded recommended loading ratio | Add 50 gallons water & agitate 2 mins |
| Foam Overflowing Tank Hatch | High-shear agitation air entrainment | GreenTack maintains a low-foaming profile during high-shear agitation |
| Nozzle Spitting or Clogging | Commodity tackifier agglomerations (fisheyes) | GreenTack's dispersion modifiers prevent fisheye formation |
