Terracon Project No. 20205032
Dear Mr. Copp:
Previously, Terracon Consultants, Inc. (Terracon) prepared a Geotechnical Engineering Report
(Project No. 20205032; report dated October 22, 2020) for the project referenced above. The
water-soluble sulfate testing was not complete at the time the report was prepared. This
supplemental letter presents the results of the water-soluble sulfate testing performed for the on-
site soils.
Results of water-soluble sulfate testing indicate Exposure Class S0 according to ACI 318. ASTM
Type I portland cement should be specified for all project concrete on and below grade.
Foundation concrete should be designed for low sulfate exposure in accordance with the
provisions of the ACI Design Manual, Section 318, Chapter 4.
Terracon recommends providing the laboratory test results regarding potential corrosive
characteristics of the on-site soils and bedrock materials encountered below this site to a
corrosion specialist to interpret the data and incorporate the test results into the design and
selection of foundations.
We appreciate the opportunity to continue to be of service to you on this project. If you have any
questions or concerns regarding the content of this report, please feel free to contact us.
