3. SOIL TYPE: Ground water laterite
• Laterites are soil types
rich in iron and
aluminum, formed in
hot and wet tropical
areas. Nearly all laterites
are rusty-red because of
iron oxides.

4. SOIL TYPE: Histosols
• Histosols - organic soils

5. SOIL TYPE: Histosols
• SUBORDERS
• Folists - Histosols that are not saturated with water for
long periods of time during the year
• Wassists - Histosols that are submerged for more than
21 hours every day
• Fibrists - Histosols that are primarily made up of only
slightly decomposed organic materials, often called
peat (RIVER BASIN)(TAFT)
• Saprists - Histosols that are primarily made up of highly
decomposed organic materials, often called muck
• Hemists - Histosols that are primarily made up of
moderately decomposed organic materials

6. Subsidence
• Subsidence is the motion of a
surface (usually, the Earth's
surface) as it shifts downward
relative to a datum such as
sea-level. The opposite of
subsidence is uplift, which
results in an increase in
elevation. Ground subsidence
is of concern to geologists,
geotechnical engineers and
surveyors.

7. SOIL TYPE: Tropofibrists/Fibrists/Peat
• These are Fibrists with an isomesic or warmer iso-
temperature regime.
• They have a mean annual soil temperature of 8°C
or higher and have greater than 5°C difference
between the mean summer and mean winter soil
temperatures at a depth of 30 cm.
• They occur in coastal mangrove swamps and
other coastal swamps and in closed depressions
of intertropical areas.

8. SOIL TYPE: Fibrists/Peat
• Fibrists Histosols that are
primarily made up of only slightly
decomposed organic materials,
often called pea
• Peat and loose waterlogged sand
are very poor subsoils. If the peat
can be stripped back to find
suitable load-bearing ground of
at least 1.5m depth, strip
foundations may be suitable. A
reinforced raft foundation will
likely be required

9. SOIL TYPE: Fibrists/Peat
• Peat in its natural state consists of water and
decomposing plant fragments with virtually no
measurable bearing strength(Munro2004).
• Peat is considered as soft soil because this soil
has high settlement value and even under
moderately applied load. These soils are found
in many countries throughout the world.
• Taft area is a waterbasin for the pasig river
so the soil is full of liquid

10. SOIL BEARING CAPACITY
• Peat soil exhibits very low bearing capacity
and this soil is not suitable for constructing
embankment, highway, building or any other
load bearing engineering structure.

11. FOUNDATION TYPE
• Raft
Foundation or
a Strip
Foundation.
• Or you can use
machines that
mix soil to
make it more
stable

12. Mass Stabilization Method;
• this method can also be used for processing
and encapsulating contaminated materials.
• Leading the way, ALLU’s Stabilization System,
which consists of three devices :
– pressure feeder,
– power mixing unit and
– control system
• – allows contractors to gain access to grounds like
swamp where it is not possible to walk.

13. PILING TYPE
• they force a
metal rod into
the ground
that equals the
estimated
weight of the
building to be
built.
