Compact Subgrade Soil

What happens here

After excavation, thoroughly compact the exposed soil floor, also known as the subgrade. Use a heavy-duty compactor to make the soil as dense and hard as possible. This step is critical to prevent the base layers from settling in the future, which can lead to an uneven patio surface. The video refers to the soil as 'sand', but emphasizes that compaction is still necessary.

Goal: Create a solid and stable base that prevents future settling.
