DOT Highway & Roadway High Solid Soil Matrix Tackifier
in Virginia

Highly erodible silty clay loams will wash away without rigorous erosion control. You must mechanically compact the subsoil and mix in chemical amendments to build structural integrity. Spray heavy-duty tackifiers and bonded fiber matrix (BFM) mulches to stop surface degradation when intense rain hits.

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 VDOT Road and Bridge Specifications, Section 303 (Earthwork) and Section 603 (Seeding) Specifications

OHRA GreenTack anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by VDOT Road and Bridge Specifications, Section 303 (Earthwork) and Section 603 (Seeding). 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.
