What is the recommended system to use when the site consists of problematic soil or it's wet?

Using slurry walls is highly recommended for sites that consist of problematic soil or are wet due to their effectiveness in providing stability in challenging ground conditions. Slurry walls act as a barrier that can prevent water infiltration and soil movement, thereby creating a more stable construction environment. This is particularly advantageous in situations where the soil may not provide adequate support for traditional foundation methods or where conditions might lead to erosion or other issues.

Moreover, the construction process for slurry walls allows for the excavation and placement of a reinforced concrete wall while simultaneously controlling groundwater, making them ideal for wet conditions. They can also be designed to various depths and configurations to suit specific site requirements, further enhancing their effectiveness in problematic soils.

While other options such as sheet piles, bearing piles, and wood piles may have their own applications, they may not provide the same level of stability and waterproofing needed in conditions characterized by wet or unstable soil.
