Landfill Closure & Cover Soil Stabilizer
in Alberta

The geotechnical conditions typically consist of glacial clay till and localized expansive smectite deposits subject to severe freeze-thaw cycles. Subsoil stabilization is critical to prevent slope failure and frost heaving. Erosion control strategies must incorporate robust soil matrix binding, while hydroseeding programs require hydraulically applied erosion control products (HECPs) capable of enduring rapid thermal fluctuations and high-velocity runoff during spring freshet.

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 Alberta Transportation Standard Specifications Section 2.20 Specifications

OHRA ViscoLok anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by Alberta Transportation Standard Specifications Section 2.20. 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.
