Building a house foundation requires precise coordination between specialists and adherence to quality and precision requirements. To ensure the quality of installation work meets reliability and safety requirements, let's look at the 5 most common mistakes made when pouring a foundation.
1. Poor preparation of the foundation and the
underlying soil
Plant
debris will eventually rot, causing foundation deformation. As the house
continues to operate, the foundation will begin to settle, resulting in cracks
in the foundation and load-bearing walls.
To prevent
this, the building site is carefully cleared of roots, rocks, plants, and
various debris.
2. Incorrect choice of concrete grade
Sometimes,
in an effort to save money, builders choose cheaper cement options, which can
cause the foundation to crumble, deform, and gradually deteriorate under low
temperatures. This can eventually lead to the collapse of the house.
For
pouring, use cement that meets frost resistance and strength requirements.
3. Insufficient reinforcement
Insufficient
reinforcement is a common cause of poor foundation quality. Incorrect placement
of reinforcement elements or insufficient quantity can lead to foundation
failure or deformation. Cracks will begin to appear on the surface within the
first few years of use. Over time, these cracks will widen further under the
influence of temperature fluctuations, frost, and moisture.
Steel
reinforcement is an essential component of a concrete structure. It is used to
increase the strength of the foundation.
4. Incorrect timing of pouring
The optimal
season for pouring a foundation is considered to be between late spring and
early summer. During this time, the ideal temperature range for such work is
+15…+25°C. When the temperature is just 5 degrees lower, concrete strength gain
slows by 3-5 times. With the onset of hot weather, concrete dries much faster,
but at the same time, it loses excessive moisture and elasticity. This is
another reason for its insufficient strength. To slow the rate of concrete
strength gain, certain measures are taken: wrapping the concrete in plastic
wrap and regularly watering it.
5. Lack of formwork or creating it from scrap
Due to
low-grade formwork materials, soil will constantly crumble from the edges of
the trench and end up in the mortar. This causes large cracks to appear in the
concrete. Consequently, its quality and strength are reduced, leading to rapid
foundation deterioration.
Therefore,
the correct and precise execution of all stages of foundation pouring
guarantees the strength and durability of the building.
