Photovoltaic Solar Array Export Grade Haul Road Dust Control Agent
in Maine

Glacial till and frost-susceptible silts will destroy your subgrade during the spring thaw unless you stabilize them against frost heave. You have a very short growing window. You must spray specialized cold-weather seed blends in a heavy hydraulic mulch matrix to establish vegetation fast and stop spring runoff from washing out your slopes.

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 MaineDOT Standard Specifications, Section 618 (Seeding) and Section 619 (Mulch) Specifications

OHRA GreenTack & ViscoLok anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by MaineDOT Standard Specifications, Section 618 (Seeding) and Section 619 (Mulch). 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.
