What is design mix testing?
Design mix testing determines the correct proportions of materials — cement, aggregates, water, and binders — to achieve the required strength and performance for your specific project. Engineers and contractors use these tests to produce an approved mix design report before construction begins.
Skipping this process, puts your project at risk of rejection during quality audits by departments like NHAI, PWD, Railways & PMGSY. Moreover, a failed pavement or structural element because of an untested mix can cost several times more to rectify than the test itself.

Who We Serve
Jancy Labs provides design mix testing services to contractors and consultants working on projects for:
Roads & Highways: NHAI, PWD, TNRDC, MoRT&H, PMGSY, Southern Railway, RVNL

Rural Development: NABARD, PMGSY, DRDA, Panchayat Raj Engineering
Energy & Industrial: TANGEDCO, SIPCOT, NTPC
Submitting a mix design report without proper testing support is, consequently, a common reason for quality audit failures on government projects. Departments increasingly require test reports that reference the applicable IS standard or MoRT&H table — and verify that the laboratory follows documented procedures.
