What is a Home Foundation
The load-bearing portion of a structure, such as your home, is the foundation. It is usually built below ground level and must perform three tasks well. It must support the structure built on top of it as well as keep groundwater out. To put it another way, it acts as a water and soil vapor barrier.
What is the strongest foundation for a house?

How long do home foundations last?
If built properly, poured concrete block footings and slab foundations should last a lifetime, 80 to 100 years or more.

How soon can bricklaying start on the foundation?
After the concrete has been poured, you must wait 48 hours. The first 500mm of brickwork can be built above the surrounding ground level. After that, thoroughly wet the concrete and backfill your trenches with soil. After seven days, the concrete foundation strips should be strong enough for your walls to be built up to roof level. At this point, the concrete should have reached 60% of its ultimate strength.
