Title: How Underpinning helps to make a Building More Stable

Stable

2- When a building has been in service for several
years, the probability of its foundation being
unstable and weak increases with time. If
movement surpasses the limit of the footing
design, additional stress on the footing can
cause them to crack, bend and/or rotate. Such
stresses will then transfer to the wall or
concrete slab above, leading to masonry cracks.
In extreme cases, it may compromise the
structural integrity of a building.

Destabilization Of A Building - Common Causes
While concrete cracks with hairline plasterwork
are considered cosmetic shrinkage issues that
demand less attention, problems like stepped or
long zigzag masonry with concrete cracks can pose
a serious threat to the stability of a building.
These cracks demand immediate investigation
before the problem gets any worse. The underlying
causes of such an issue may include the
following The mix used for casting the wall was
not compatible with the surface on which it was
poured. The concrete was poured without proper
vibrators or vibrator pads. Too much water was
added during mixing. There were water seepage
problems after casting had been completed.
4Poor Construction Methods

- The problems with construction practices are not
limited to improperly trained workers. Inadequate
concrete curing, lack of formwork support,
insufficient concrete compaction, and adding
water to concrete in the field can cause crack
development in plastic and hardened concrete.
These mistakes reduce concrete strength, which
makes concrete prone to cracks at lower tensile
stress than the design calculations

Additions and Alterations in the Building
When considering an extension to the existing
building, it is crucial that the proposed
extension design take into consideration the new
project's impact on the existing building
foundation. When adding a new level to a
building, it may be necessary to upgrade the
builder's foundations to take the extra load.

Changes In The Environment
If you've ever wondered why your building is
sinking or tilting, then you must read
this! Your building's foundation system can be
affected by many different things, including
natural and man-made changes. Whether your home
was originally built on concrete piles or screw
piles foundation system, it's unlikely to be
affected by environmental changes. However, a
single slab can be affected if the following are
taking place nearby Removing nearby
trees Change in level of water-table Change in
soil moisture content Excavations taking place
nearby Nearby water-bore or dewatering activity
7Underpinning For Foundation Repair Or Stability
05.
If you notice cracks in your ceiling or floors,
it's probably time to get a building inspection.
If the foundation is sinking, it may be because
of soil problems. Even if there are no visible
signs of trouble, you can still ask for an
inspection. This method is effective in
increasing the depth of the buildings foundation
and is great for reinforcing faulty foundations.
It can also help when new additions or
alterations are made to any existing building or
when the foundation happens to be damaged in any
way. Cracks on the ceiling floors are the first
signs of problems with the foundation that should
not be ignored at all.
8Some more problems that may demand underpinning
06.
The building's original foundation is not stable
because the wooden piles underneath the
foundation have started decaying. The building's
usage has changed over time. There has been
change in the properties of the foundation
supporting soil. Soil excavation is taking place
in nearby construction sites.
