Landfill Closure & Cover High Solid PAM Alternative
in Missouri

Freeze-thaw cycles and heavy seasonal rain force you to phase your erosion control tightly. You must spray deep-rooted native seed that can break through hard claypan. Condition the moisture, compact the dirt, and use chemical stabilizers to stop rutting and fix the bearing capacity of plastic residual soils.

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 MoDOT Standard Specifications for Highway Construction, Section 806 Specifications

OHRA GreenTack anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by MoDOT Standard Specifications for Highway Construction, Section 806. 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.
