Mine Tailings & Quarry Pump Friendly Soil Capping Matrix
in Maryland

MDOT SHA forces you to hit strict stabilization timelines—you only have 3 to 7 days to spray before you get cited. You must till the seedbed and mix in pulverized dolomitic limestone to stabilize the subsoil. Spray your hydroseed immediately to stop rill erosion across disturbed soils.

Operational Constraints for Mine Tailings & Reclamation

Mine tailings and quarry cuts present one of the most hostile environments for revegetation. These sites feature extreme pH imbalances, sterile particulate matter, and unnaturally steep cut angles. Airborne toxic dust is an immediate operational hazard that triggers severe MSHA and EPA environmental fines. Standard agricultural hydroseeding fails completely in these sterile conditions. The site requires a heavy-duty, high-viscosity soil capping matrix that locks down dust instantly upon application and provides a highly retentive micro-environment to force seed germination in otherwise dead soil.

Meeting 2011 MDE Standards / MDOT SHA Section B-4 Specifications

OHRA ViscoLok anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by 2011 MDE Standards / MDOT SHA Section B-4. 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.
