Recommended Foundation for Low Bearing Capacity Soil and Heavily Loaded Walls

There are various types of foundations available for construction. The choice of the foundation type depends on the soil type, the bearing capacity of soil, load requirements, and other site-specific conditions. When the bearing capacity of soil is low but walls are heavily loaded, the following foundation type is recommended:

Pile Footing with No Cap

Pile foundation is a type of deep foundation that is used when the soil at the shallow depth has low bearing capacity. In this type of foundation, piles are driven into the ground to transfer the load to a deeper and more competent soil layer. When there is a heavy load on the walls and columns, pile foundation with no cap is preferred.

Advantages

- Pile foundation is suitable for low bearing capacity soil.
- It can transfer heavy loads to a deeper and more competent soil layer.
- The pile foundation is suitable for a variety of soil conditions.
- It provides high resistance to lateral and uplift forces.
- Pile foundation with no cap is cost-effective because there is no need for a concrete cap.

Disadvantages

- Pile foundation requires skilled labor for installation.
- It is time-consuming to install a pile foundation.
- Pile foundation requires heavy machinery for installation.
- The cost of pile foundation is higher than a shallow foundation.

Conclusion

In conclusion, pile foundation with no cap is recommended for low bearing capacity soil and heavily loaded walls. It is a cost-effective and efficient solution for transferring heavy loads to a deeper and more competent soil layer. However, it requires skilled labor and heavy machinery for installation. The choice of the foundation type should be made after a thorough analysis of site-specific conditions.
