Soil Investigation: The First Step to a Safe Building

Soil Investigation: The First Step to a Safe Building

Every safe building begins below the ground. Soil investigation, also called subsoil investigation, tells engineers exactly what they are building on.

What is a soil test?

A soil test involves boring into the ground, collecting samples and testing them in a laboratory. The Standard Penetration Test (SPT) is the most common method used in Bangladesh.

What the report tells you

  • Soil layers and their strength
  • Bearing capacity for foundation design
  • Ground water table level
  • Settlement and liquefaction potential

Why you should never skip it

Designing a foundation without soil data is guesswork. Skipping the test can lead to cracks, tilting or even collapse. The small cost of a soil test protects a very large investment.
