Landfill Closure & Cover High Solid Tackifier
in Arequipa

Steep topographical gradients combined with highly erodible volcanic soils dictate the implementation of high-tensile geocellular confinement systems for erosion control. Hydroseeding operations demand specialized soil amendments and high-performance flexible growth media to promote adhesion on friable slopes. Subsoil stabilization requires careful compaction moisture control and potential mechanical stabilization to counteract the high void ratios inherent to regional volcanic deposits.

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 MTC Peru Highway Manual - Soils, Geology, Geotechnics and Pavements Specifications

OHRA GreenTack anchors seed and mulch directly to the subsoil, providing the rain-fast shear strength required by MTC Peru Highway Manual - Soils, Geology, Geotechnics and Pavements. 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.
