As a barrier against moisture,
TF Sealant is so effective that, when used in sufficient concentrations, it
makes a flexible liner useful in the fortification of ponds,
embankments, and landfills.
When properly applied to virtually any soil in sufficient
quantities, TF Sealant controls problems with dust pollution,
soil erosion, and base failure.
TF Sealant can be used on Air Fields, Dams, Driveways, DUST CONTROL, EROSION CONTROL,
GROUND COVER (in place of plastic liners and gravel) PARKING LOTS, PONDS, RACEWAYS,
RECYCLING ASPHALT (using a cold-in-place method), RESERVOIRS, ROAD CONSTRUCTION, ROOFING
(to seal leaking tar based flat roofs), SEEDING (allows germination by holding soil and
moisture is place), WALKWAYS.
TF Sealant
is an excellent and cost effective
substitute for lime and other traditional base stabilizers.
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 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 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.
Full Base Stabilization and Cold-in-Place
Recycling:
TF Sealant is easily accommodated into routine
construction procedures with no precautions.
TF Sealant can be used to stabilize
virtually any soil base by simply applying it in quantities that would be sufficient to
bind and transform the base into a solid mass of tightly cemented soil particles.
The newly stabilized base will yield a significant increase in soil bearing capacity and
it will create a much greater resistance to the invasion of moisture.
When used as
an additive for cold-in-place recycling of old asphalt roads, TF Sealant is an excellent
alternative to asphalt emulsion, and can be used as the major component in one of the most
effective techniques available for road base re-construction.
After TF Sealant
is
mixed in place with the old asphalt and the existing base of a worn roadway, it interacts
as a powerful binder that keeps all of the soil and asphalt particles tightly cemented
together.
After compaction, a new and superior base is created, at tremendous
savings.
The primary difference between using TF Sealant as a stabilizer and using it
as a sealant as described above is that a large portion of the product will first be
thoroughly mixed into a road base (or parking lot, etc) until optimum moisture density has
been reached.
The road base will be shaped and compacted through normal construction
procedures and just prior to final compaction an additional application of TF Sealant
will
be soaked into the upper base in order to achieve extra strength and resistance to
moisture.
Lab analysis has shown TF Sealant to improve soil strength by as much as
3,000 percent! Compared to other products, TF Sealant contains no acids, corrosives,
enzymes, chlorides or lime.
Equipment:
Although there are many types of equipment used in
construction of roads, all that is required for the effective use of TF Sealant is a MOTOR
GRADER, WATER TRUCK, and a COMPACTOR.
When using TF Sealant for Cold-in-Place
Recycling, a recycler such as a BOMAG MPH 100 will produce excellent results. The
water truck and compactor as described above for controlling dust are also essential for
stabilization.
It is important to note that proper road construction and proper
implementation of TF Sealant into a road base are directly related to product performance
capabilities.
The three most important factors in using TF Sealant for soil
stabilization and re-cycling is PROPER DILUTION, EVEN DISTRIBUTION INTO THE SOIL, and GOOD
COMPACTION.

Frequently Asked Questions
Question #1 - What is in TF Sealant that makes it so
much better than other soil stabilizers?
Answer - TF Sealant is a proprietary blend of copolymers. No element, or
combination of elements, before, during, or after manufacture, is 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.
Question #2 - How much TF Sealant do I need?
Answer - 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.
Question #3 - How do I apply TF Sealant?
Answer - 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.
Question #4 - How much does TF Sealant cost?
See Below
Question #5 - Why is TF Sealant more expensive per
square yard than other stabilizers?
Answer - 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.
Question #6 - Why should I buy TF Sealant when there
are less expensive stabilizers?
Answer - 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.
