New foundations are structures built to support buildings, roads, bridges, and other structures. They are usually made out of thick concrete and steel bars, and they help keep the structure from sinking into the ground or falling over. Think of it like building a house – you need a strong and solid foundation for the walls and roof to sit on top of. New foundations are needed when you want to build a bigger and better version of something you already have, or if the ground has shifted and the old foundation is no longer stable. Without a good foundation, the building would be unsafe and could even collapse!
