DOT Highway & Roadway Dune Stabilizing Tackifier
in Oklahoma

Intense storms and long droughts mean your erosion control must handle extreme hydrologic swings. You must spray organic mulches and moisture-retaining polymers to establish vegetation fast. Mix fly ash or cement into expansive red clay to stabilize the subgrade and stop volumetric changes.

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 ODOT Standard Specifications Section 220 and 221 (Temporary Sediment Control) Specifications

OHRA GreenTack anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by ODOT Standard Specifications Section 220 and 221 (Temporary Sediment Control). 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.
