TF Sealant is an all-in-one general-purpose, environmentally safe, low cost liquid solution soil hardener. It can be mixed with water to control and manage a variety of soil conditions:

1. As a barrier against moisture. TF Sealant is so effective that, when used in sufficient concentrations, it can be transformed into a flexible liner which could be useful in the fortification of ponds, embankments, and landfills.

2. When properly applied to virtually any soil in sufficient quantities, TF Sealant will effectively control problems associated with dust pollution, soil erosion, and base failure.

TF Sealant is superior in comparison to the competitors. 

TF Sealant is an excellent and cost effective substitute for lime and other traditional base stabilizers.

General Guidelines:

Dust Control and Soil Erosion Control

TF Sealant is highly effective against the problems associated with dust pollution and soil erosion. The product is simply mixed with water and applied over the surface of the area of coverage with a minimum of two applications. When properly applied in sufficient quantities, TF Sealant will quickly dry into a hardened membrane, which will trap soil particles and loose aggregate, and as a side benefit, it will provide excellent upper level base stabilization. All that is needed is a water truck or other means of even 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.

How well does it work? A picture is worth a thousand words!

Equipment. The above process is typically accomplished 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.

TF Sealant TF Sealant is totally environmentally safe, and is certified as such.

A letter is available which states the following:

TF Sealant Liquid Pond Sealant and Stabilizer is an all-purpose liquid additive for all types of soils used in the construction of earthen ponds. The product is specially formulated to give maximum strength and moisture resistance for base applications.

TF Sealant is an excellent alternative to the costly options of excavating and replacing unsuitable soils or installing other types of expensive liner systems. The product is easy to use and it requires no special equipment or handling procedures. It is simply integrated into routine construction procedures by adding it into the water of a water truck and distributing it evenly throughout the area of coverage. After compaction, the end result is a greatly strengthened and superior pond base, which will prevent leakage and costly future repairs.

Erosion Control / Seeding

Save time and money using our TF Sealant process. Don't worry about your seed washing away. Grow grass through our TF Sealant if the mix is 10 parts water to 1 part TF Sealant. The best stabilization (Erosion Control) process.

The TF Sealant process is easily accommodated into routine procedures with no requirement for special equipment or handling procedures. Broadcast grass seed over a designated area, cover grass seed with a thin layer of composted material or soil, at least 1/4 inch, then apply TF Sealant to top layer of soil. You will be amazed at how your grass will grow and how it will control the erosion. Grass grows very well through TF Sealant diluted 10 to 1. TF Sealant acts like a plastic wrap, coating the area trapping the moisture into the soil. It allows the seeds to germinate faster. Water could still be applied to the surface and water will penetrate into the soil.

This is one product contractors, nurseries, erosion control specialists and others cannot do without!!

Environmentally Safe: One of the most important benefits of using TF Sealant for the construction of earthen ponds is that is environmentally safe. There are no toxic or hazardous chemicals used in the manufacturing of TF Sealant, and when fully cured, it will not re-disperse back into the pond. Fish studies have been conducted with TF Sealant and there are reports available upon request. TF Sealant contains no acids, corrosives, enzymes, chlorides, or lime. As a Barrier Against Moisture: TF Sealant is so effective that, when used in sufficient quantities, it can ultimately be transformed into an impermeable moisture resistant liner. Unlike other liquid additives, when fully cured, TF Sealant will not re-disperse in water or rain, and it is not affected by degradation from alkaline materials and sunlight. Compared to other products, TF Sealant contains no acids, corrosives, enzymes, chlorides, or lime, and the cost savings over geo-textile lines is more than 50 percent TF Sealant Liquid Soil Sealant and Stabilizer sometimes stymies people with its simplicity. TF Sealant's environmental safety, ease of calculation, and simplicity of application often lead potential users to doubt its efficiency and longevity. "It sounds to good to be true" is often heard but, it's true!

Frequently Asked Questions:

What is in TF Sealant that makes it so much better?
TF Sealant is a proprietary blend of copolymers. No elements, or combination of elements, before, during, or after manufacture, are included on the USEPA's list of hazardous chemicals. There are no petroleum, or petroleum based, compounds in TF Sealant, alleviating this worldwide concern. Rather than counting on mystic "ion exchanges", or causing physical or chemical changes in the soil, or providing for temporary (biodegradable) stabilization, TF Sealant's copolymer construction binds to itself and the soil as it cures; it binds larger aggregate and suspends the finer materials in a complex, long lasting, matrix of interwoven polymer chains.

How much TF Sealant do I need?
As with other forms of stabilization, TF Sealant will work somewhat differently in different types of soil. Generally, the more granular a soil, the more product would be required. A general rule applies that 1/2 gallon of a 1:10 mixture of TF Sealant and water, applied to soil to reach Optimum Moisture Content (OMC), then thoroughly compacted, will achieve superior to excellent base and sub-base stabilization in most soils in the AASHTO spectrum. Due to the need to provide for wear and tear when used on unpaved surfaces, TF Sealant applied to the surface in a 1:5 ratio will allow most surfaces to remain pothole and dust free for a significantly longer period of time than with any other product.

How do I apply TF Sealant?
TF Sealant is mixed in a water truck to the proper proportions and applied to the soil surface in two passes. The first pass will use 1/2 of the mixture over the area to be treated. After allowing the product to soak in to the soil for 1-2 hours (depending on local and soil conditions) the truck direction is then reversed (to offset variations in the spray bar) and the remaining 1/2 of the mixture is then applied. This method is used whether one is stabilizing or controlling dust/erosion. The only major difference between the stabilizing or controlling dust/erosion is that when stabilizing, common soil preparation and subsequent compaction methods are used depending on the depth of the soil to be treated. When controlling dust or erosion, TF Sealant is simply applied to the surface of the area requiring treatment and allowed to soak in. NOTE: If this latter area is loose soil, some compaction after application may be necessary. Conversely, if the area to be treated in densely compacted already, the area should be scarified and then lightly compacted prior to applying TF Sealant as a stabilizer or dust/erosion control.

Why is TF Sealant more expensive per square yard than other stabilizers?

TF Sealant is more expensive to produce than other stabilizers due to its unique chemical nature. Thus, ounce per ounce, TF Sealant is more expensive than other stabilizers. Also, because TF Sealant is applied to the soil in quantities that produce results superior to the other stabilizers (which are sometimes applied at centiliters per square yard), the net cost of the initial application of TF Sealant will generally be more than with shorter lived stabilizers.

Why should I buy TF Sealant when there are less expensive stabilizers?
Quality, longevity, and lower long-term costs. The savings realized over the years on reapplication, equipment maintenance, and personnel costs, will more than adequately repay the initial costs of TF Sealant. Comparisons between TF Sealant and other types of stablizers

Sulfuric Acid
More expensive than TF Sealant per area of coverage. Most expensive shipping rates. Very toxic. Flammable Corrosive – damages equipment. Environmentally unsafe in the delivered containers. Crystallizes minerals in the soil. Disposition of empty containers must be accordance with EPA regulations.

Enzymes
More expensive than TF Sealant per area of coverage. Resolubilizes (re-liquefies) more easily in soils with lower percentages of fines, (i.e. washes out). Recommendation application rate is much lower than TF Sealant, yet there is no evidence that is a stronger, even at equal concentration.

Calcium Chloride
More expensive than TF Sealant per area of coverage. Surface applied. Goes on concentrated. Only penetrates 1 to 3 inches below the surface. Therefore, load bearing capacity is much less than TF Sealant. Corrosive. Very Slippery when wet.

Lignosite
More expensive than TF Sealant. Derivative of tree sap. Re-solubilizes (re-liquefies) easily. Used mostly for dust control. Not as well known for serious base stabilization, although advertised as such. Often advertised as bio-degradable. Lime and soil cement Much more expensive than TF Sealant. Very dusty. Harmful to equipment, vegetation and people. Special equipment and handling required.

Application / Dilution Dust Control:
Non-traffic areas  - 55 gallons of Sealant to 400 gallons of water per surface acre

Traffic Areas – 75 gallons of sealant to 260 gallons of water per surface acre Stir and apply with conventional spray equipment. Use large droplets and avoid spraying as a fine mist.

Coal Piles – To prevent excess water penetration apply 3 coats as follows per surface acre: First Coat – Dilute 55 gallons of Sealant 8:1 with water and apply in large droplets. Second Coat – Dilute 55 gallons of Sealant 4:1 with water and apply in large droplets.

Third Coat – Dilute 55 gallons of Sealant 2:1 with water and apply in large droplets. Allow 2-3 hours drying time

Erosion Control – Coal Storage, fine powders (coke and metallic ores); 110 gallons of Sealant 4:1 with water per surface acre. Apply half of total in each of two applications with 1-2 hours drying time between coats. Use at least two spray passes to prevent excessive runoff during application.

Soil Stabilization – Per surface acre – 100 gallons of Sealant, 1500 gallons of water, 600 pounds of wood fiber, and fertilizer and seed as required.

Road Base Stabilization:
Ease of Use -  There are no special requirements for equipment or handling procedures. This product is simply mixed with water and dispersed into the soil in quantities that are sufficient to control major soil problems such as soil erosion, dust pollution and upper level base failure. When properly applied, TF Sealant will quickly dry into a hardened membrane and, unlike competitive products, it will not re-disperse when exposed to moisture.

Soil Conditions – All soil types are suitable for TF Sealant. However, due to fluctuating absorption rates associated with different soils, the amount of required TF Sealant may vary from one application to another.

Base Preparation – There is little or no requirement for extensive base preparation of scarification. If the lower base of the area of coverage is relatively stable, then the TF Sealant can easily be applied to the surface to achieve moisture resistance and elimination of dust. An ideal soil condition consists of lose, dusty soil on the surface, but otherwise is relatively stable in the lower base. If the base is rutted and “wash-boarded”, then some surface blading may be required to produce a smoother surface prior to applying TF Sealant. When properly used, TF Sealant will tightly bring lose soil and aggregate into a hardened surface which should remain stable, dust free and moisture resistant. Base Reconstruction - If base reconstruction is required, it is important to note that the base must be compacted and cured prior to using TF Sealant.

If the base is not compacted, or if it remains in a fluffed condition, then the TF Sealant may be absorbed too deeply into the lower base thereby leaving too little concentration for upper base hardening. Dilution and Application – TF Sealant can be used in any concentration that yields satisfactory results.

First Application:
Will penetrate from 1-3 inches into the soil and will serve as a primer for the second application, which will settle closer to the surface. The first application should be completely distributed throughout the area of coverage, and allowed to soak thoroughly into the soil for at least one hour prior to initiation of the second application. All of the soil must be completely covered with TF Sealant, even to the extent that an extra pass during the first application may be required over the area of coverage.

Second Application:
Is the sealing application, which soaks into the soil at a much slower rate and will bind to the first application. Most of the product will be concentrated near the surface and will form a hardened membrane, which will trap dust and aggregate and will resist the invasion of moisture, and if used in sufficient concentrations, it can ultimately transformed into a flexible liner.

TF Sealant Soil-Binding Product Instructions

TF Sealant acts like glue for soil. It increases soil strength by 2,000 to 3,000 percent, and successive applications serve to strengthen the previous applications.

You can use it in varying concentrations. If it's used in a very light strength, it will make the soil harder and hold plants in the soil to resist wind erosion for growing crops.

It could be used in a light strength (10 parts water to 1 part sealant) to calm down the dust in livestock yards (or orchards) without negatively affecting the soil for growing (or making cattle stand on a concrete like surface).

It can also be mixed extra strong to make a better base for building roads than what is currently used for that purpose (1 parts water to 1 part sealant).

The rule of thumb for applying the TF Sealant for dust control is an easy formula.  Dust proofing (and mud proofing) driveways is an easy place to start.  Multiply the width of the area to be applied by the length to get the square foot area. A ten-foot wide driveway that is 100 feet long would have 1000 square feet of TF Sealant to apply. Multiply the square feet by .01 to get the gallons of product needed. 1,000 X .01 is 10 gallons of product for this application.

When applying TF Sealant you need to get moisture content of 7% to assure good coverage. You achieve that by doing two applications. Do one in the morning and the second a few hours later (or longer). The first pass uses 1/3rd of the product mixed with water at ten to one. To do the driveway, above, that would be 33.3 gallons of water mixed with 3.3 gallons of TF Sealant (1/3rd of 10) is applied first. A few hours later (at least two) apply the rest at a 5 to 1 ratio, or 33.3 gallons of water mixed with 6.6 gallons of product.

There is no preparation needed for dust control, although you may want to have the driveway graded before applying to get out and bumps and ruts. The reason you do a 10-1 ratio on the first pass and a 5 -1 ration on the second pass is that the 10-1 ratio is very diluted and will penetrate deeper into the soil. The 5-1 ratio is a less diluted, thicker mixture, but it will follow the path of the 10-1 mixture and as a rule of thumb will penetrate about 3 inches into the soil. This will give you a great dust and mud-controlled surface. Remember, with additional application, previous layers re-bind with the new application, so the next year you can re-apply the 10-1 mixture to re-new your application.

To make a roadway that is hard like bricks, you need to break up the soil with a blade or some other piece of equipment to create 4 to 6 inches of loose dirt. Mix sealant in a 1 to 1 ratio with water. Apply it to the area, ¼ gallon per square yard and blade it over or some way mix the sealant in thoroughly. If it is not mixed in it will not work because it will not penetrate in that thick a mixture. Go over the area with a compactor to compact the dirt. Wait a day and then put a sealing layer with the same ratio. Add as many wearing layers as you want.
