Landfill Closure & Cover Slope Stabilizing 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 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 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.
