For medium to large scale projects, hydroseeding is the most economical and basic form of seed establishment utilized for turf & native grasses, wildflowers, and erosion control mixes.

  • Regionally selected seed varieties

  • Fertilizer component tailored to site conditions

  • Hydro mulch fiber to aid in uniform seed disbursement & moisture retention

  • Tackifier to bind the slurry for uniform seed to soil contact during establishment

Straw Blowing

Straw blowing is the most cost-effective method to reduce soil erosion and sediment runoff on active and inactive construction sites. This methodology provides superior erosion control protection by limiting soil particle run-off resulting from rainfall at construction sites.
• Mechanically applied at rates determined by analyzing site conditions
• Sealed in place with Hydro mulch and Tackifier to reduce wind erosion if required.
