Type C wall has a specific advantage in installation. What is it?

Type C walls are specifically designed to be directly buried in applications such as underground installations. This characteristic allows for a streamlined installation process, particularly in certain environments where traditional methods might be cumbersome or require additional excavation. When walls can be directly buried, it reduces the need for significant support structures or complicated installation procedures that would otherwise be necessary for walls that require more elaborate foundations.

The direct burial feature of Type C walls ensures that they can perform effectively in environments where they must withstand soil pressure and moisture conditions without requiring an extensive footing or backfill procedure. This can lead to a more efficient installation process and can also enhance the structural integrity of the wall in specific applications where moisture protection and soil interaction are critical.

The other options do not capture the unique advantage offered by Type C walls. While aspects like requiring less concrete or potentially handling curved runs may be advantageous, they do not align with the specific installation benefits provided by the ability to be directly buried.
