Civil Construction Site Bio Based Seed-to-Soil Encapsulator
in Massachusetts

MassDOT rules demand you grade the topsoil and remove clods to guarantee your hydroseed slurry sticks. You must spray organic soil conditioners and wood fiber mulch to create a bonded fiber matrix. This locks down the subsoil and forces stormwater to infiltrate the ground during severe rain instead of washing out your site.

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 MassDOT Standard Specifications Edition 2026 Specifications

OHRA GreenTack anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by MassDOT Standard Specifications Edition 2026. 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.
