A thin concrete layer, typically unreinforced, serves as a ground cover often installed beneath the main concrete slab of a building. It acts as a barrier against moisture and pest intrusion. Consider its use in environments where soil conditions are poor or where a controlled sub-slab environment is desired.
The advantages of employing this method include mitigating the risk of rodent infestation, creating a cleaner workspace during construction, and reducing the potential for moisture migration into the primary foundation. Historically, it represents an evolution in building practices, moving toward enhanced sanitation and structural integrity, especially in regions prone to pests or dampness.
