Foundations and Floors

Foundations are the underground structures that support buildings, while floors are the horizontal surfaces you walk on inside. Think of foundations as the invisible backbone keeping your house from sinking into the ground.

The main types of foundations include shallow foundations (like strip footings used in most Nigerian homes) and deep foundations (like piles for buildings on weak soil). Shallow foundations work well on firm ground, but deep foundations are necessary in areas with soft clay or swampy terrain.

Floors come in different types too: concrete slabs, timber floors, and raised floors. Many Nigerian buildings use reinforced concrete ground floors because they're durable and affordable. The parts of any floor include the base layer, structural members, and the wearing surface you see.

Understanding how foundations and floors work together is essential because poor design causes cracks and structural failure.
