DOT Highway & Roadway High Solid Hydroseeding Slurry Binder
in Mississippi

Frequent, intense rain will wash out your saturated alluvial slopes without strong temporary and permanent erosion controls. You must add heavy-duty tackifiers to your hydroseed to stop runoff. Mix lime or cement into the expansive clay subgrades to stop them from swelling and shrinking.

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 MDOT Standard Specifications for Road and Bridge Construction, Section 212 Specifications

OHRA GreenTack anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by MDOT Standard Specifications for Road and Bridge Construction, Section 212. 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.
