Tips to Building Strong Foundation Design

Civil Engineering Tips

Building Foundation is the most important step of any construction project. Foundation of any building is under the plinth level up to the soil level. Pouring strong foundation which can support the load of the complete structure and can transfer it to the ground, requires proper designing and civil knowledge.

Here are some useful construction tips for building strong foundations.

  • The soil on which the structure is to be built should be strong. The building foundation should be continuous.
  • The soil under the foundation should be dry. If the foundation is built on waterlogged soil then this may lead to liquefaction and sinking of structure into the ground in case of earthquake.
  • Different factors affect the depth of foundation such as: bearing capacity, shrinkage and swelling of the ground due to seasonal changes, depth of frost penetration, excavation allowance, ground water table, etc. Considering these factors, the minimum depth of foundation should be 1.5 m.
  • Rounded and unbroken stones should not be used for building foundation, only broken stone can create strong foundations.
  • Sufficient mortar should be used to join stones. If need may be, reinforcements can be used to enhance the overall strength of the structure.

Footing is the structure beneath the base of the wall or column which distributes the load to the wider area of foundation. The minimum width of footing for one brick wall is considered to be 75 cm and for 1m for one and half brick wall.
