WHAT IS SOIL TESTING?
Soil testing is the systematic laboratory evaluation of soil properties — including strength, compressibility, and gradation — that determine how a material will perform under structural load. Tests are conducted under Indian Standard IS 2720 (various parts), which governs everything from moisture measurement to bearing capacity testing.
Submitting reports from a non-NABL-accredited soil testing laboratory increases the risk of departmental rejection, re-testing costs, and project delays — particularly on NHAI, PWD, and PMGSY contracts that require ISO/IEC 17025:2017 compliant documentation.
FULL TEST LIST
Each test is conducted with precision, reinforcing our reputation as a reliable testing lab.

WHY CHOOSE JANCY LABS FOR SOIL TESTING?
Jancy Labs Private Limited is accredited by NABL vide Certificate No. TC-12176 under ISO/IEC 17025:2017 — your soil test reports meet the documentation standard required by NHAI, PWD, TNRDC, and PMGSY contracts across Tamil Nadu..
Calibrated equipment specific to soil testing
Our Casagrande apparatus, CBR loading frame, direct shear box, and compaction moulds are calibrated on schedule. Your results reflect instrument accuracy, not instrument age.
Tests conducted strictly per IS 2720 — no shortcuts
Sample preparation, conditioning periods, and test durations follow IS 2720 exactly. Your CBR report states the correct soaking period. Your compaction curve shows all plotted points, not just the peak.
Reports are accepted by NHAI, PWD, TNRDC, PMGSY, and CPWD
Clients across Tamil Nadu have submitted our IS 2720 test reports to these departments. Acceptance depends on your project’s quality plan — confirm with your quality engineer before dispatch.
Turnaround confirmed before you dispatch
We agree your turnaround time before you send the sample. Results are dispatched by courier or you can collect it from out office.

WHO WE SERVE
Road contractors, highway consultants, and structural engineers across Tamil Nadu submit soil test reports generated under IS 2720 to the following departments and agencies.
Roads and highways
Clients have submitted our CBR, compaction, and gradation reports to NHAI, NHIDCL, PWD Tamil Nadu, TNRDC, MoRT&H, PMGSY, Southern Railway, RVNL, and IRCON for highway, expressway, and rail project quality control.
Buildings and urban infrastructure
Clients have submitted our CBR, compaction, and gradation reports to NHAI, NHIDCL, PWD Tamil Nadu, TNRDC, MoRT&H, PMGSY, Southern Railway, RVNL, and IRCON for highway, expressway, and rail project quality control.
Water and irrigation
TWAD Board, Water Resources Department (WRD), CMWSSB, and TNIDB clients submit our embankment and subgrade soil reports for reservoir, canal, and pipeline project quality documentation.
Rural development
NABARD, PMGSY, DRDA, and Panchayat Raj Engineering contractors submit our IS 2720 compaction and CBR reports as part of rural road quality assurance files.
Submitting a soil test report from a laboratory that is not accredited under ISO/IEC 17025:2017 creates audit risk. Departments may require re-testing at a recognised laboratory, delaying progress certifications and payment.
