What should not be conducted while wet?

1. Excavation for absorption trenches

2. Excavation for foundation footings

3. Installation of drainage pipes

4. Placement of concrete slabs

The correct answer is: Excavation for absorption trenches

Excavation for absorption trenches should not be conducted while the ground is wet because it can lead to several issues that affect both the integrity of the work and the performance of the absorption system. Wet conditions can cause the soil to become loose and unstable, making it difficult to create the required trench depth and stability for effective drainage and absorption. Furthermore, saturated soil may reduce the ability of the absorption trenches to function properly, leading to water pooling and potential system failure. In contrast, excavation for foundation footings, installation of drainage pipes, and placement of concrete slabs can typically be done in manageable wet conditions, provided that proper precautions are taken, such as ensuring proper drainage and soil compaction techniques. These processes may also involve materials that can function adequately even in less-than-dry conditions, making them more flexible in terms of weather dependency.
