Airtrol® Geobinder

Spray applied gypsum binder for erosion control suitable for a variety of water- and wind-induced erosion sites.



Spray applied gypsum binder for erosion control
Suitable for a variety of water- and wind-induced erosion sites, Airtrol® Geobinder applies faster and with less site preparation than erosion control netting or blankets, requiring only normal seeding surface preparation.

Main Features

Produced from high purity mined gypsum, Airtrol® Geobinder is a mineral based binder which, when mixed with water and mulch and sprayed through hydraulic equipment, sets in a controlled, predictable way to bind soil particles and form an erosion-resistant crust. Airtrol® Geobinder is:

  • Nontoxic, noncombustible, pH neutral and harmless to fish, birds, plants and animals
  • Suitable for all disturbed soil surfaces whether inclined or flat, multiple soil types,landfill final covers, commercial and residential construction, golf course construction, mine reclamation and around water retention ponds
  • Cost-effective; can be used with a wide variety of mulch (cellulose or wood fiber)
  • Helpful in promoting plant growth by providing Calcium and Sulfur, acting as a flocculent for heavy clay soils to increase water penetration to root systems
  • Effective in holding both seed and fertilizer in place in contact with the soil surface and upon degregation over time providing nutrient value to the soil profile

q & a

  • How do I mix plaster?

    You will need a bucket, scale and mixing equipment. Mixing could be accomplished through basic hand mixing with a large spoon, but mechanical mixing is preferred. An electric drill with a cage mixer head attached is good for small batches.

    The first step involves measuring and adding enough water to the bucket to achieve the desired consistency. You then need to weigh out enough gypsum plaster to meet the proper ratio for the selected water volume. Sift the plaster into the bucket of water and allow the plaster to soak for 1 to 2 minutes. Follow this immediately with mixing, generally for 1 to 2 minutes based on product.

    NOTE: If mixing by hand, use vigorous stirring action. After mixing and pouring the gypsum slurry, make sure to clean all tools and the mixing vessel before the plaster hardens.

    For more detail on mixing, see USG publication IG503, Plaster Mixing Procedures.
