Mine Tailings & Quarry High Tenacity Erosion Control Matrix
in Alaska

Permafrost melt and deep freeze-thaw cycles will wreck your subgrades. You must monitor embankment temperatures constantly. Because the growing season is so short, your hydroseeding mix needs rapid-germinating, cold-tolerant seed locked inside a heavy bonded fiber matrix to stop surface erosion when the spring thaw hits.

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 AKDOT&PF Section 618 Specifications

OHRA ViscoLok & GreenTack anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by AKDOT&PF Section 618. 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.
