What it is
Soil is described by what it is made of (sand, silt, clay, gravel, rock) and how much load it can carry. Chennai has sandy soil near the coast, clayey and soft ground in low-lying areas, and firm or rocky ground in parts of the west and south.
Key points
- Sandy soil drains well but can shift if loose
- Clay swells when wet and shrinks when dry
- Filled or marshy land may need deeper foundations
- Rock gives excellent support but is costly to excavate
Why it matters
The same house can need very different foundations on two plots a few streets apart. Only a soil test tells you for sure.
How Elamentt handles it
A soil test report is part of every package, and the foundation is designed from it.
