What it is
Piles are bored or driven many metres down and capped with a beam or slab on which the house is built. They carry load by resting on firm strata below or by friction along their length.
Key points
- Used where soft clay or filled land goes deep
- Bored cast-in-situ piles are common in cities
- Cost more and need specialist rigs
- Common in low-lying and once-marshy parts of Chennai
Why it matters
On weak ground, ordinary footings can settle unevenly and crack the house. Piles avoid that, at a cost you should know before you buy or plan.
