TerraHold 402
TerraHold 402 is a dry powder polymer soil stabilizer that is most effective working in soils with fine grain clay content and in climates with mild to medium precipitation. This polymer reinforces the structure of the treated soil while providing some flexibility. It also biodegrades between 6 to 9 months following application, but it can be reapplied for continued usage. The 9 month life is ideal for construction sites and farming land where the application needs to be temporary. TerraHold 402 leaves only a slight trace of acetic acid when it biodegrades and almost no environmental footprint.

Use Guide
Application
Soil stabilization can be achieved by mixing dry powdered TerraHold 402 into soils at a depth of 4" or greater at a rate of 1% to 2% by weight of the soil. Water is then added to reach the optimal moisture content, and the soil is compacted to reach maximum compaction density. Once dry, TerraHold 402 will have an increased compressive strength approximately 3.5 times greater than untreated soil.
Properties
TerraHold 402 is a dispersible VAE polymer powder and contains no water. This reduces transportation costs compared to diluted liquids. The flexibility of powder also facilitates direct mixing of the product into soil and determining the optimum moisture content of soil when adding water. TerraHold 402’s formulation allows it to be diluted and applied on the job site with non-potable water.
Cost
Approximate cost of applied product runs between $0.30 / sq ft ($3.23 sq meter) and $0.43 / sq ft ($4.73 /sq meter), depending on the depth of treatment.
- Strengthening and stabilizing soils for heavily used dirt roads, exposed soil production areas, hardstands, runways and parking aprons
- Wind and rain erosion control of soils requiring moderate water-repellency
- Hardstands and other soil areas where a light water repellent surface is needed
- Erosion control and hillside stabilization
