Dust Control and Soil Erosion Control

TF Sealant solves problems associated with dust pollution and soil erosion.  Simply mix it with water and apply it to the surface with a minimum of two applications.  When adequately applied, TF Sealant dries into a hardened membrane, which will trap soil particles and loose aggregate, and as a side benefit, will provide excellent upper level base stabilization.  All that's needed is a water truck for distribution of TF Sealant.

Simply apply a mixture of TF Sealant and water directly over the area of coverage with two or more applications and allow each application to thoroughly soak into the upper levels of the soil.

After compaction, the end result is an elimination of dust and a highly effective barrier against moisture.  When the mixture of TF Sealant and water has been absorbed completely into the soil, a curing process will transform TF Sealant from a liquid into a solid, thereby trapping the dust and solidifying the ground into a hardened and moisture resistant membrane.

Equipment: You can do this with a water truck supporting a spray bar mounted 12 to 30 inches above the ground.  A "rubber tire" compactor is useful in providing immediate compaction, but if not available, the area coverage will eventually be compacted by routine traffic.

Soil Type: In general, soils which are more sandy or granular will require higher concentrations of TF Sealant. Most other soil types will require a minimum dilution rate of 1 part TF Sealant to 5 parts water.

Soil Conditions and Preparation: Soil should be fairly dry on the surface and fairly stable in the lower base.  If the lower base is not stable, or if the base has not been compacted after construction, then efforts should be made to stabilize and shape the base prior to treatment for controlling dust or soil erosion.  Refer to stabilization section below

Application and Penetration: There should always be at least two applications of TF Sealant into any area of coverage.  The first application serves as a primer while the second application functions as a sealant.

The ideal depth of penetration for the TF Sealant is 1 to 2 inches.  This can be achieved in most soils which fit into the soil types and conditions described above.

If the product cannot sufficiently penetrate the soil, then it is recommended that the soil be lightly scarified or bladed with a motor grader prior to treatment.  After TF Sealant is applied, then the soil should be compacted as thoroughly as possible.

Maintenance Applications (Re-applications): Depending on soil type, traffic, and weather conditions, it may be occasionally necessary to re-apply TF Sealant to unpaved surfaces.

New applications of TF Sealant will easily blend in with the previous applications, thereby creating a "build-up" factor, which will reduce the frequency of future applications.

It should be noted that the savings from using TF Sealant on unpaved roads could often be reprogrammed into future funding of paved roads.  The presence of TF Sealant in the base will generally provide sufficient stabilization, thereby eliminating the cost of re-building the base.
