Extreme 1:1 Steep Slope High Solid Soil Capping Matrix
in Pennsylvania

Annual freeze-thaw cycles will trigger frost heave and destroy your materials unless you stabilize the subsoil. You must prepare for violent spring runoff events. Spray a bonded fiber matrix with heavy tackifiers to lock your seed onto moderate and steep embankments before they wash away.

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 PennDOT Publication 408, Section 804 Specifications

OHRA ViscoLok anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by PennDOT Publication 408, Section 804. 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.
