WHY DO BUILDINGS USE RAFT FOUNDATIONS? 🏗️ | Engineering Whys

Why do some buildings need a giant concrete foundation covering almost the entire building footprint? 🏗️ In this episode of Engineering Whys, we explore raft foundations (mat foundations) and understand why engineers use them. You'll learn: 🏗️ What is a raft foundation? ⚖️ How does it distribute building loads? 🧱 Why are rafts useful when individual footings become too large or overlap? 🌍 How soil bearing capacity affects foundation selection 📉 Settlement and differential settlement 🔩 Bending, shear & punching shear 🏢 Different types of raft foundations 🕳️ Raft foundation vs isolated footing vs pile foundation 📋 Why soil investigation is essential before foundation design Engineering isn't just about building things — it's about understanding WHY they work. Don't just see it.
