LI: to learn the different types of foundation
This week for Inquiry, Mr Ogilvies Inquiry group talked about different types of foundation. The were five they learned. The first was the slab foundation or slab grad. The slab foundation is when you dig a whole. Then fill it up with some concrete. Then also add some bars to give more strength for it to support the weight of what of a structure. The next foundation is called the Pier or Pile footing. A pier foundation is like a fence. You dig a hole, then put a wooden stick, or stone, then fill it up with concrete. They would normally support the weight of a house. It can support it by having a surface on the large stick. Then they would build the structure on top of the foundation. The walls are their to make rooms and separate rooms from each other. But they also support the weight of floors and roofs. You dig a hole, then put the wall in. After that fill in the hole with concrete to keep it stable and still. Then they learned about the column foundation. A column foundation is a structure that is under concrete and made as a base of a wall. The foundation is part of the structure that directs contact with the soil that loads into it. Then lastly they learned about the Cassen foundation. The cassen is a watertight retaining structure used as a bridge. The construction of a concrete dam, or for repair of ships.
