Landfill Closure & Cover High Solid Erosion Control Matrix
in Indiana

Diverse glacial soils and a transitional climate mean you must anchor clay-heavy roadway embankments with deep-rooting native hydroseed. If you don't manage moisture and chemically stabilize the subsoil, prolonged spring rains and freeze-thaw cycles will cause complete slope failure.

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 INDOT Standard Specifications (Section 205 - Stormwater Management, Section 621 - Seeding and Sodding) Specifications

OHRA ViscoLok & GreenTack anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by INDOT Standard Specifications (Section 205 - Stormwater Management, Section 621 - Seeding and Sodding). 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.
