3. Foundations

Question 1

What are the FOUR common forms of foundation?

Answer 1

1. Trench and strip footings – residential
2. Raft – a slab foundation that spreads the load of the property over the whole site, for lightweight structures and soft soil conditions (think TITANTIC RAFT)
3. Piled – Long and slender reinforced concrete cylinders in to the ground vertically, to deeper strata. Used for less good load bearing ground / high loads.
4. Pad – a slab foundation, under individual columns or units so that the column load is spread evenly.
