Soil Testing Lab in Bengaluru — Geotechnical Analysis

NABL accredited geotechnical soil testing per IS 2720 at our lab on Bagalur Main Road, Yelahanka, Bengaluru. CBR, Proctor, field density, and classification tests.

Geotechnical Soil Testing for Bengaluru Construction

Bengaluru's varied soil conditions — from red laterite to black cotton soil — demand thorough geotechnical investigation before construction. V2 Civil Diagnostics performs a full range of soil tests including CBR, standard and modified Proctor compaction, Atterberg limits, and field density measurements. Our results guide foundation design, road subgrade evaluation, and earthwork specifications. All tests follow IS 2720 methods under NABL accredited, ISO/IEC 17025:2017 certified protocols. We serve residential, commercial, and infrastructure projects across Bengaluru and North Karnataka.

Frequently Asked Questions — Soil Testing

V2 Civil Diagnostics is a NABL accredited soil testing lab on Bagalur Main Road, Yelahanka, Bengaluru. We serve projects across the city, including Yelahanka, Devanahalli, Jakkur, and North Bengaluru.

California Bearing Ratio (CBR) measures the strength of subgrade soil. It is essential for road pavement design and is required by NHAI, KPWD, and BBMP for road construction projects in Bengaluru.

Yes. Our team visits your site in Bengaluru for field density testing using the core cutter method per IS 2720 Part 29. This is commonly required during earthwork compaction checks.

Bengaluru's geology includes red laterite soil, red sandy soil, and pockets of black cotton (expansive) soil in some areas. Our soil classification tests (sieve analysis, Atterberg limits, free swell index) help identify the soil type at your specific site.

For a standard suite of tests (CBR, Proctor, Atterberg limits, sieve analysis), approximately 30-50 kg of representative soil is required. Our team can guide you on proper sampling.

Most soil tests are completed within 5-7 working days. CBR (soaked) requires a 4-day soaking period as per IS 2720 Part 16 before testing, which extends the turnaround.
