Civil Testing

In any civil construction, mainly buildings, fly overs, highways etc. there is a greater need for ensuring safety and longevity; There is also a growing awareness among builders, consultants, architects to test the quality of construction related materials.

In recognition to this fact, it is highly imperative that raw materials used in the construction should be tested in conformance with appropriate standards.
