Mine Tailings & Quarry Dot Spec Soil Matrix Tackifier
in Gauteng

High-intensity summer thunderstorms and massive seasonal swings will wreck your site. You must mix chemicals into the subsoil to stop massive shrink-swell behavior. Spray drought-tolerant pioneer seed and moisture-retaining mulches to lock down long-term erosion control.

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 SANRAL Standard Specifications for Road and Bridge Works Specifications

OHRA GreenTack anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by SANRAL Standard Specifications for Road and Bridge Works. 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.
