    Ground improvement refers to the application of geotechnical construction techniques to improve the performance of soils. These techniques are used when existing soils cannot provide satisfactory support of the planned structure. They improve the ground performance by increasing the strength and stiffness of the soil mass through densification, reinforcement, and/or cementing of soils. This course introduces ground improvement technologies and provides an in-depth review of aggregate piers and their design, installation, and benefits.

    Trees are essential for the health of the urban environment, mitigating the heat island effect, cleaning the air, reducing stormwater runoff, and improving residents’ health and well-being. But cities are often inhospitable to trees, where their growth may be stunted or their roots may damage surrounding infrastructure. This course explores ways to design successful projects incorporating green infrastructure by understanding the principles behind tree growth, proper type and amount of soil, water management, and the role of soil vault systems in helping urban trees thrive.

    Radon is a colorless, odorless gas, a Class A carcinogen, the leading cause of cancer after smoking, and the leading cause of death for nonsmokers. It is found in soil, rock, and groundwater. If radon enters a home through slabs, basements, and crawl spaces, breathing it can lead to illness or even death. This course examines how the gas travels through soil and into structures and the various interception approaches and materials that can be utilized to prevent entry into inhabited spaces. It also highlights building code requirements and language that can assist with ensuring the correct radon interception systems are designed and installed effectively.
