Pump Friendly Seed-to-Soil Encapsulator
in Washington

Diverse topography and massive annual rain demand adaptable erosion control. You must lay robust drainage and geogrid reinforcement to stabilize glacial till subsoil. Spray flexible growth mediums (FGM) mixed with deep-rooted native seed to stabilize slopes and stop sediment from dumping into critical watersheds.

Operational Constraints for Large-Scale Civil Projects

Large-scale earth-moving operations expose vulnerable subsoil to immediate wind and water shear. Traditional stabilization methods require excessive manual labor, heavy equipment tracking over finished grades, and frequent repeat applications after weather events. You require a high-yield hydraulic matrix that locks down the slope in a single pass. The binder must flow smoothly through the hydroseeder pump without fisheye clumping, maximizing your tank yield and eliminating the need for constant mechanical agitation adjustments on the job site.

Meeting WSDOT Standard Specifications for Road, Bridge, and Municipal Construction, Section 8-01 (Erosion Control) Specifications

OHRA GreenTack anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by WSDOT Standard Specifications for Road, Bridge, and Municipal Construction, Section 8-01 (Erosion 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.
