The Reed Engineering Group was founded in 1988 on a basic tenet: provide a comprehensive approach for commercial, large industrial, and municipal clients. With drilling, testing, and analysis preformed in-house, results are innovative and cost-effective. Understanding soil suction is critical to evaluation of the strength and performance of unsaturated soil. Without suction measurements, the geotechnical engineer is making an educated guess of soil performance. With over 500,000 measurements taken since 1988, the Reed Engineering Group understands unsaturated soil performance.
