Specific Gravity Test Lab in Madurai | Jancy Labs

Your soil’s specific gravity affects every foundation, fill, and compaction decision on site. Consequently, getting it wrong means approvals stall and projects delay. Jancy Labs provides Specific Gravity of Soil testing in Madurai as per IS 2720 Part 3 Section 1. Furthermore, our NABL accredited lab (TC-12176) delivers reports accepted by NHAI, PWD, and PMGSY.

What is Specific Gravity of Soil?
The Specific Gravity test tells you the ratio of soil particle density to water density. Consequently, this foundational value helps your geotechnical team calculate void ratio, porosity, and degree of saturation. Without this value, however, soil classification and compaction design remain incomplete. Furthermore, submitting an incomplete soil test report to NHAI or PWD can delay your project approval by weeks.
Applicable Standards
IS 2720 Part 3 Section 1 prescribes the exact procedure, equipment calibration, and calculation method for this test. Consequently, any deviation from this standard invalidates the result for government project submissions. Therefore, Jancy Labs conducts Specific Gravity testing strictly as per IS 2720 Part 3 Section 1 — no shortcuts, no approximations.
Why This Test Matetrs
- Foundation design depends on it. Specifically, void ratio and porosity calculations critical for foundation sizing require a verified Specific Gravity value.
- Road project compliance is non-negotiable. Therefore, NHAI, PWD, and PMGSY require Specific Gravity data as part of subgrade soil characterisation before approval.
- Additionally, without accurate Specific Gravity, your Maximum Dry Density from the Proctor test loses its precision.
- Furthermore, IS classification of fine-grained soils directly relies on Specific Gravity for degree-of-saturation calculations.
- Consequently, Panchayat Raj Engineering and NABARD-funded projects require complete soil test packages, including Specific Gravity.
- Moreover, an incorrect Specific Gravity value cascades into wrong fill design, wrong settlement predictions, and ultimately expensive site corrections.
Skipping the Specific Gravity test — or using an unaccredited result — therefore risks rejection of your entire soil test report by the approving authority.
Why Choose Jancy Labs for Specific Gravity Tetsing?
We run Specific Gravity testing on a calibrated pycnometer setup maintained specifically for IS 2720 Part 3 compliance. Furthermore, this is not a shared, multi-purpose instrument — it is dedicated entirely to this test.
- Calibrated pycnometer and constant-temperature water bath — dedicated specifically to Specific Gravity testing
- Specific Gravity test conducted strictly as per IS 2720 Part 3 Section 1 — consequently, no procedural shortcuts
- Every Specific Gravity report is therefore signed and reviewed by a Materials Engineer
- Additionally, Jancy Labs holds NABL accreditation — Certificate TC-12176 under ISO 17025:2017
- Furthermore, reports are accepted by NHAI, PWD, and PMGSY for road and infrastructure projects
- Moreover, contractors and consultants across Tamil Nadu trust Jancy Labs for Specific Gravity testing
Our NABL accreditation under ISO 17025:2017 means every result carries independent third-party verification. Additionally, this accreditation is what makes our reports accepted by government departments.
How To Get Your Test Done
1st step : Send Sample with covering letter (Contact our team to confirm exact quantity for your soil type before dispatch)
- 2nd step : We Test It
- 3rd step : You Receive Your Certified Report (courier or collect directly)
Our Specific Gravity Test Process
- First, the sample is received, logged, and assigned a unique ID on arrival.
- Subsequently, the soil sample is air-dried and prepared as per IS 2720 Part 3 requirements.
- Next, the pycnometer is cleaned, dried, and its mass recorded accurately.
- Then, the soil sample is introduced into the pycnometer and de-aired thoroughly.
- Furthermore, the pycnometer is filled to the mark with de-aired water at constant temperature.
- Subsequently, mass readings are taken at each stage — soil, pycnometer, and water.
- Consequently, Specific Gravity is computed using the standard IS 2720 Part 3 formula.
- Finally, the result is reviewed for repeatability and signed off by a Materials Engineer before dispatch.

1. How long does a Specific Gravity test take at Jancy Labs?
Jancy Labs completes Specific Gravity testing within the standard turnaround period specified under IS 2720 Part 3 Section 1. Actual time depends on sample receipt and current queue. Therefore, we recommend calling us at +91-8680049004 before dispatch to get a confirmed timeline for your project.
2. Can I send my soil sample by courier to Jancy Labs?
Yes — Jancy Labs accepts soil samples via courier, transport service, or direct drop-in at our Madurai lab. Seal your sample securely in a double-sealed polythene bag inside a rigid container. Additionally, WhatsApp us at +91-8680049004 after dispatch so we can track your sample arrival.
3. Is your Specific Gravity report accepted by NHAI and PWD?
Yes. Jancy Labs holds NABL accreditation under ISO 17025:2017 (Certificate TC-12176), and consequently our Specific Gravity reports carry the NABL stamp. These reports are accepted by NHAI, PWD, PMGSY, and Panchayat Raj Engineering departments for project submissions.
4. Do you test Specific Gravity for different soil types?
Jancy Labs tests Specific Gravity for fine-grained soils — including clayey, silty, and mixed soils — as per IS 2720 Part 3 Section 1. If your site has coarser material or specific borrow area soil, contact our team first. We will confirm the appropriate test method for your sample before you dispatch.
5. How much soil sample do I need to send for a Specific Gravity test?
The sample quantity follows IS 2720 Part 3 Section 1 requirements. For most fine-grained soils, a representative disturbed sample of adequate mass is sufficient. However, exact quantity depends on your soil type. Call Jancy Labs at +91-8680049004 before collecting your sample — we will guide you correctly.
