How can you construct a building foundation in an area with black cotton soil?

Question

Accepted Answer

Building foundation in black cotton soil areas requires proper soil investigation and engineering techniques.

Conduct a thorough soil investigation to determine the properties and behavior of the black cotton soil.
Design the foundation based on the soil investigation report, considering factors like soil bearing capacity, settlement, and potential soil movement.
Implement appropriate foundation techniques such as deep foundations (piles or piers) to transfer the load to more stable soil layers.
Consider using ground improvement methods like soil stabilization or soil replacement to enhance the soil's load-bearing capacity.
Ensure proper drainage and moisture control to prevent excessive swelling or shrinkage of the black cotton soil.
Monitor the foundation during and after construction to detect any signs of soil movement or settlement and take necessary remedial measures.

Accepted Answer

Building foundations in black cotton soil requires specific strategies to mitigate the soil's expansive nature. This includes using lime concrete instead of standard cement concrete, implementing deep foundations like piles or under-reamed piles, and considering raft foundations to distribute the load. Additionally, it's crucial to prevent water from entering the soil by using a damp-proof course and a well-designed drainage system.

decision as per IRC SP 13 clause 20. ground Improvement. Black cotton soil remove and back fill GSB or Granular soil.

Accepted Answer

check the SBC test as per design load of our structure .our SBC less the design load then we take the decision as per IRC SP 13 clause 20. ground Improvement. Black cotton soil remove and back fill GSB or Granular soil.

Accepted Answer

In black cotton soil, lime concrete is effective as it alters the characteristics of the expansive soil
