DOT Highway & Roadway High Solid Hydroseeding Slurry Binder
in Arkansas

Constant rain and rolling hills mean surface runoff will cut deep rills and gullies into your site. When working in alluvial plains, you must lay geogrids or mix in lime to stabilize the weak subgrade. Spray hydraulically applied erosion control blankets (HECBs) to lock your seed to the soil on critical embankments.

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 ARDOT Section 620 Specifications

OHRA GreenTack anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by ARDOT Section 620. 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.
