Landfill Closure & Cover High Solid Erosion Control Matrix
in Ontario

The presence of sensitive marine clays and consolidated glacial tills mandates careful geotechnical evaluation for subsoil stabilization to prevent catastrophic shear failure. Erosion control methodologies must manage prolonged saturation and freeze-thaw degradation. Hydroseeding solutions are required to utilize high-performance mulches and engineered soil amendments to facilitate immediate surface protection and promote deep-rooting vegetative stabilization.

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 Ontario Provincial Standard Specifications (OPSS) 803 and 804 Specifications

OHRA ViscoLok & GreenTack anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by Ontario Provincial Standard Specifications (OPSS) 803 and 804. 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.
