Mine Tailings & Quarry Organic Soil Matrix Amendment
in Quebec

Severe freeze-thaw cycles will destroy sensitive marine clays. You must spray deep-rooting vegetation to hold the surface. Control the moisture and lay heavy geosynthetic reinforcement to stabilize the subsoil and stop differential settlement and shear failure in Champlain Sea clay deposits.

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 MTMD CCDG (Cahier des charges et devis généraux) Standards Specifications

OHRA GreenTack anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by MTMD CCDG (Cahier des charges et devis généraux) Standards. 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.
