What is the composition
PX300 is a special blend
of enzymatic polymer emulsions developed by the G.M. Boston
Company. Development began in 1998 and several improvements have
been made to the formula to increase its ability to bind soil
particles, making the soil very dense and resistant to water
penetration. When used for various soil stabilization projects,
PX300 is diluted with water
of soil will PX300 stabilize?
PX300 can be used with a
wide variety of soil types, from sandy to hard clay. This
versatility is accomplished by varying the dilution rate of PX300 to
water in the application process. More concentrated
product/water mixture will stabilize very sandy soil, while dense
clays will require a less concentrated product/water formula to
fully stabilize. Here are some examples of soil types that
PX300 can effectively stabilize:

Does rain, snow or hail
cause deterioration to roads, trails or pads constructed with PX300
Roads constructed with
PX300 are highly impermeable and highly compacted. We actually
have achieved permeability levels of 2 x 10-9 cm/sec
under ASTM 5084 and compaction results as high as 95%. Because
potholes result from water penetration, the water resistant quality
and density of PX300-bound surfaces eliminate the need for
constant road maintenance after seasons of rain and storms.
Can PX300 stabilized
soil withstand freeze/thaw cycles?
applications are not affected by freezes closely followed by
thaws. The impermeability of PX300 treated roads means
that no cracks due to standing water during thaw periods will
undermine the integrity of the surface.
As an example, a PX300
road base finished with a chip-seal surface in the County of San
Bernardino, CA, has withstood 5 years of freeze/thaw weather without
any maintenance needed.
Does heavy traffic
affect PX300 stabilized roads?
Roadbeds and unpaved roads
constructed with PX300 are highly durable. In laboratory
testing, PX300/water/soil combinations have produced unconfined
compressive strenght levels of 1233 LBS/PSI (ASTMD 2166).
Such strength will endure heavy traffic easily.
How does PX300 save
construction and maintenance costs?
There is no need to import base material, if
PX-300 is used in road or pad or field construction.
PX-300 is mixed with
onsite soil to produce a solid base.
Adding PX-300 to base material reduces
costs in two ways due to its extremely low; permeability.
First, the low permeability of the PX-300
base reduces the occurrence of potholes, thereby saving on

Second, if an additional asphalt wear
surface on a road is desired, the asphalt surface can be much thinner than
is required for traditionally constructed roadbeds. Reducing
the amount of asphalt means big savings. In some situations, a chip-seal surface is
all that is required, resulting in additional savings.
In other situations, no additional surface is
desired and is not needed. For example, Px-300 was used to
construct a one-half mile road for the County of Riverside, CA, over
three years ago, without any additional surfacing. The road has
carried at least 500 cars/day and has held up entirely satisfactorily
during this time period without additional maintenance.
Will PX300 harm the environment?
No. PX300 is a totally
environmentally safe, non-toxic chemical. It will not harm
plant, aquatic, or animal life. Recent leachate tests found that
no harmful substances leached into surrounding soil from applications
of PX300.. See the page on LAB TESTS to see the actual results
of the Leachate tests.
Will PX-300 harm plants, animals
or aquatic life?
PX-300 is entirely non-polluting and safe. It is non-toxic,
non-carcinogenic, non-flammable, non-combustible. It can be
safely used for hydro seeding. We have included the PX 300 MSDS on another
How does PX300 control dust and
When a very dilute solution of
PX-300 is sprayed over dusty soils, the product binds the soil to a
depth sufficient to trap surface particles that would otherwise be
blown by the wind or washed away by rain.
The crusty cover will last
throughout several seasons, if not disturbed.
However, the surface can easily be broken up for use in
agriculture or construction operations. Px300 dust applications
help contractors, and governments avoid sanctions for air quality
violations that often crop up during construction
PX-300 is compatible with hydro-seeding,
because the PX-300 treated soil allows plant life to grow
and enables germination to take place uninhibited by wind or
Will PX-300 change the
appearance of the natural soil material?
PX-300 is white in color, but will turn
transparent as it dries. It therefore does not give an
industrial look to native soil, making it effective for nature trails
and rural roads. In this regard it is superior to geo-membranes
or other geo-synthetic fabrics. The addition of a chip-seal wear
surface gives the project a more urban look.
