Mine Tailings & Quarry Export Grade EFM Hydromulch
in Texas

Texas terrain demands aggressive geotechnical intervention. The expansive clay subsoils—predominantly Houston Black and related Vertisols—are defined by severe shrink-swell capacity. During the intense, short-duration storm events characteristic of the region, these clays resist immediate moisture penetration. This creates a high-velocity runoff coefficient that generates extreme hydraulic shear, stripping unbonded seed, mulch, and weak agricultural tackifiers directly off the slope. When bare soil on a large-scale earthwork is exposed, TCEQ runoff regulations require immediate, structurally sound stabilization to prevent catastrophic sediment loading into local watersheds. Water and conventional crimped straw will not hold this topsoil against sheet erosion.

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 TxDOT Item 164 Specifications

OHRA ViscoLok anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by TxDOT Item 164. 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.
