Condor Soil Stabilizer

Condor SSCondor Soil Stabilizer, also known as Condor SS, is a sulphonated oil product derived from a petroleum waste product which has been treated and processed to be environmentally safe. Sulphonated oil is particularly effective as a soil electrolyte because of its high chemical stability with powerful ionizing capabilities.

Simply stated, sulphonated oil ionizes the excess water found in expansive clay soils, which vigorously exchanges its electrical charges with the soil’s particles, causing the water that adheres to the particles to break their electrochemical bonds and separate, thus becoming free water, which drains through gravity, evaporation, and compaction.

Because of textural changes caused by these reactions within the soil, the strength and moisture stability of these soils is improved and swelling is reduced.

Condor SS can be used to pre-treat construction projects in locations with expansive clay soils, which are prevalent throughout the world. Our products have been used to stabilize locations such as the 150-acre Frisco Square in Frisco, Texas as well as Dallas/Ft. Worth Airport, as well as individual home building projects, gravel and paved road development, and application worldwide in Japan, China, Australia and more.

Expansive Clay Soils

Swelling in clay soil is caused when clay attracts and retains water. This happens because tiny, but powerful, electrical charges present in the soil attract the moisture. Condor SS neutralizes this problem by introducing more ions with an opposite charge from those in the clay. Once the ions in the clay have been neutralized, the clay no longer attracts water. Weight applied on top of the clay can compress it, collapsing the capillaries that had previously carried water. With the capillaries collapsed, and no attractive force pulling water into the clay, the clay becomes ideal for supporting roads, runways, homes, and other structures.

Clay masses draw moisture on a grand scale, attracting hundreds of gallons of water. This creates vast numbers of small voids, or capillaries, that act as passageways for the water. These capillaries exist throughout the clay mass, like infinite “veins” where water can travel. As the water is pulled into these tiny pathways, soil swells to make room for the water. The swelling can easily break apart roads and lift a home or office building off its foundation, sometimes as much as 15 inches.

Stabilized Clay Particles
Clay particles after stabilization and compaction: no longer bound with water molecules.

Once clay has absorbed water once, the capillaries provide passageways for the water to flow in and out of the clay depending on factors such as rainfall, irrigation, temperature etc. This causes the characteristic cracked look of dry clay, as it shrinks back to its normal size. Clay is always cycling between being moist and holding water, and shrinking to become dry and cracked. For this reason, untreated clay is not a stable building surface.

How Do I Combat The Effects of Expansive Clay Soil?

The expansion and contraction of soil with clay content can be avoided by injecting Condor SS – Soil Stabilizer. This can be done either before or after construction, working to prevent damage or to correct problems following damage previously caused by untreated soil. Treatment is fast, easy, inexpensive, and permanent. Changes in moisture due to the changing seasons or other factors, will no longer cause damage from heaving and swelling soil.
