NABL-Accredited Soil Investigation in Chennai
Frequently Asked Questions
Why is a soil test mandatory before building a house?+
Without knowing the Safe Bearing Capacity (SBC) of the soil, your structural engineer will either over-design the foundation (wasting lakhs of rupees) or under-design it (risking building collapse and settlement cracks).
How many boreholes are needed for a typical 30x40 residential plot?+
For a standard 30x40 or 30x50 plot (1200 - 1500 sq.ft) planning a G+2 structure, 2 boreholes of 10-15 meter depth are usually sufficient to capture the soil profile.
Is soil in Chennai suitable for normal isolated footings?+
It depends heavily on the zone. Areas like Anna Nagar and T-Nagar usually have good hard soil allowing normal footings. Coastal areas (ECR, OMR) often have loose sandy or clayey soil requiring raft or pile foundations. Only a soil test can confirm.
How much does a soil test cost in Chennai?+
Pricing depends on the depth and number of boreholes. A standard 2-borehole test for a residential plot typically costs between ₹15,000 to ₹25,000, including the NABL lab report.
