Sub-Base Stabilization

Sub-Base Stabilization

The sub-base layer serves three functions. First it protects the sub-grade from over stressing. Second it provides a platform for the wear course layer. Third it serves as a drainage and filter layer. The United States Department of Transportation generally recommends that the minimum soaked unconfined compressive strength requirement for a cementitious sub-base be at 250 psi or greater. Soils and Sand stabilized with a very low dosage of our Envirotac line of polymers can easily achieve a soaked UCS many times greater than 250psi. Use Envirotac to create a stable and durable sub-base that when constructed will cater to heavy traffic and can absorb more deflection than any other stabilizer available on the market.

Binding Fine Particles

A major reason for a poor performance of a flexible pavement is movement of fine particles under pressure in the
sub-base layer. Using Envirotac eliminates the movement of fine particles because of its binding properties
performing at a nano level.

Increase PSI

Envirotac will increase load bearing PSI on all soils. We have lab results where we have increased CBR over 650%. If any
soil is in question send it to our in-house lab and we can test it.

Conservation

An Envirotac constructed sub-base eliminates the need to import gravel by binding in-situ soils, achieving better
compaction and strength than a gravel built sub-base.

Time and Money

Envirotac is easy to apply and saves time and money building a sub-base when compared to traditional methods. One crew
can easily treat a kilometer or even a mile a day.

Does Not Leach

Once Cured Envirotac will not re-emulsify and wash away or leach with water.

Environmentally Friendly

Our Envirotac line of polymers are manufactured with the Environment in mind. They are safe to treat soils with
and will not harm humans or wildlife.
