Landfill Closure & Cover High Solid Soil Matrix Amendment
in Queensland

Highly reactive Vertosols and dispersive Sodosols demand aggressive erosion control. You must spray a heavy-duty hydroseed and hydromulch matrix that can survive high-intensity cyclonic rainfall. Use chemical amelioration to stop volumetric changes and stabilize the pavement subgrades long-term.

Operational Constraints for Landfill Closure

Daily and intermediate landfill covers face severe wind erosion, off-gassing, and strict regulatory leachate controls. Loose soils blow offsite or wash into drainage systems, instantly triggering compliance violations. The objective is to seal the surface without adding excessive weight or moisture to the waste mass. You need a high-viscosity hydraulic hydro-cap that forms a durable crust over the refuse. The polymer must lock in dust and aggressively repel rainwater to prevent it from infiltrating the cell and increasing the site's expensive leachate treatment volume.

Meeting TMR MRTS16 / MRTS04 Specifications

OHRA GreenTack anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by TMR MRTS16 / MRTS04. 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.
