Permanency of Treatment with Condor SS

… “It has been our experience and my observation so far that we have yet to find a condition where we have applied Condor SS to soils with sufficient clay content that the stabilization so far has not been of a permanent nature.”

– Tom Lyshaug, P.E.; Director of Public Works, Multnomah County, 1984

Multnomah County Surface Management

“We have observed that the addition of Condor SS in the moisture that we add to the asphaltic concrete mix improves upon the product in several ways. It…allows us then to use the lanes just paved instead of having to travel on tacked road. It also seems that the rains we have occasionally during the operation do not cause as much damage as anticipated.”

– Tom Lyshaug, P.E.; Director of Public Works, Multnomah County, 1985

California Dept. of Fish & Game Test Results

“The use of Condor SS in accordance with the manufacturer’s recommended methods and rates of application, does not appear to create conditions that would be adverse or deleterious to fish, wildlife or water quality”

– Michael E. Rugg, California Department of Fish & Game, 1991

USDA Forest Service Report

“Clays have extremely low permeability, and yet the reactions between the stabilizer solutions and the clays were observed to proceed at a rapid rate in all the case studies”

“In a number of case studies on treated subgrade soils (1, pp. 55,62), the clay fraction hardened irreversibly, leaving the mixture unaffected by moisture and highly resistant to erosion; formerly the mass would have dissolved in a heavy rainfall”

Douglas E. Scholen, USDA Forest Service, Atlanta, Georgia, 1995

Compaction Test Results, Post-Injection

Treated & Untreated Soil Test Results

“Based upon the results shown in Table 1, it appears that the swell was reduced by approximately 46 percent at the depth of 4 to 6 feet after 12 days of curing and 75 percent reduction in swell at the same depth after a 27 day curing period.”

R. Edward Medrano & Robert P. Arias, P.E., Professional Service Industries, Inc, 1992

Swell Test Results – Soiltech Engineering & Testing

“Subsequent to injection, the swells were reduced to less than one percent, average. No single swell exceeded 2 percent.”

– Jesse Coleman, P.E., Soiltech Engineering and Testing, 1993
