DOT Highway & Roadway High Solid Soil Matrix Tackifier
in Pennsylvania

Annual freeze-thaw cycles will trigger frost heave and destroy your materials unless you stabilize the subsoil. You must prepare for violent spring runoff events. Spray a bonded fiber matrix with heavy tackifiers to lock your seed onto moderate and steep embankments before they wash away.

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 PennDOT Publication 408, Section 804 Specifications

OHRA GreenTack anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by PennDOT Publication 408, Section 804. 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.
