Foundation
of building as the name implies is the starting of a building
construction on site really. Types of building, nature of soil and
environmental conditions are the major determinant of type of foundation
you will use for your building.

1)Strip
foundation-This is the most common type, it is mainly used where you
have strong soil base and non-waterlogged areas. Most small buildings of
just a floor are constructed with this type of foundation .

Depends
on the structural engineers recommendation , the depth of your
foundation could be from 600mm to 1200mm mostly for small scale
buildings . When the soil is excavated, a level at which the concrete
will settle evenly is established, then concrete is poured this may be
from 150mm(6”) thick to 450mm(18”) thick depending also on building
after that block is set round the trenches at the center of foundation
,the foundation usually follows the block lines. The blocks are then
layed to d.p.c level before another concrete is poured on top, this is
the german or oversite concrete. This type seems to be the cheapest.

2)Pad
foundation-This is where isolated columns (pillars) are casted from the
foundation to carry a slab at the top of the ground. This is mostly
used when you want to make use of the under of building as parking space
or when the other space is not conducive to have foundation. Imagine
you are planning to build a house across a flowing stream and
|
|
|
you
want a situation where you can use your boat to pass under the building
because the stream is under . Then you may not need to dig foundation
that will cut across the river but just by applying columns (pillars) at
the edge of the river like a bridge, this columns are thus isolated and
there foundations are reffered to as pad.

3)Raft
foundation-This is where you have concrete spread around your building
from the base of foundation all through to the german floor/oversite
concrete/ground floor slab. It is mainly used in areas where the soil
are sandy and loose, you spend more on this than the other previous two
most of the time. It is also recommended in waterlogged areas but with
buildings of lessstoreys.

It
has a ground beam which shuts out from the foundation base and is also
attached to the ground floor slab to form a network of concrete embedded
round the building space. The ground beam are usually from 600mm to
1200mm for low buildings.

4)Pile
foundation-The most expensive and the strongest type of foundation,
this requires specialist engineering to do. The soil are bored deep down
the earth and filled with concrete to be able to support loads of
multistory building on top. Most skyscrapers are constructed with this
foundation type, a waterlogged area of high building may also require
this.

It is the costliest hence it is used for high rise building mostly. Read More...
