Landfill Closure & Cover High Solid EFM Hydromulch
in Manitoba

Aggressive spring runoff will destroy flood-prone embankments unless you lay specialized geotextiles. You must spray rapid-germinating cover crops in a heavy-duty hydromulch to stabilize disturbed slopes fast. Mix lime or cement into the deep lacustrine clays to build bearing capacity and stabilize the subsoil.

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 MTI (Manitoba Transportation and Infrastructure) Standard Construction Specifications Specifications

OHRA ViscoLok anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by MTI (Manitoba Transportation and Infrastructure) Standard Construction Specifications. 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.
