When it comes to analyzing strength and safety of a building, it’s important to do a thorough test of every aspect. And with modern science, there’s no point of doing just an assumption with experience-based human checkup — there might be errors, says the senior roof waterproofing Kolkata engineer Mr.Koushik Sarkar of Procon Tech Services.
Ultrasonic Pulse Velocity (UPV)
Measuring concrete strength is one of the prime factors when you start checking the health of a building. UPV is the most efficient and accurate tools that measures the uniformity and detect cracks, voids, or areas with deteriorated concrete using ultrasonic sound. UPV is vital for non-destructive testing, ensuring structures are stable without causing damage.
Rebound Hammer
Is the surface of your building’s concrete hard enough? Here’s rebound hammer test comes handy! The rebound hammer measures the force of a spring-loaded plunger rebounding off the surface, providing insights into concrete strength. It is commonly used for quick on-site evaluations.
Ground Penetrating Radar (GPR)
It may sound similar to UPV; however, it’s actually used to find out objects below the surface, like rebar, voids, and cracks by sending electromagnetic waves. It’s highly accurate and gives you a clear vision under a concrete slab without the need to break it. This tool is crucial for assessing hidden structural components, ensuring thorough inspections of concrete slabs and walls.

Laser Scanning/LiDAR
Have an old structure without a proper structural drawing? Want to create fresh diagram and find out any deformity or misalignment through 3D model? Then you have our latest LiDAR (Light Detection and Ranging) and laser scanning technology that can do it in the most effective way, says a roof waterproofing Kolkata engineer. These models help identify potential structural weaknesses with high accuracy, enabling proactive maintenance.
Digital Crack Monitors
Cracks in any concrete building is a symptom of structural error. And if it grows over time, it’s a symptom of serious issue. This device monitors such progression of cracks over time and gives you a better understanding of the seriousness of the fault. By tracking crack width changes, engineers can determine whether a structure is stable or deteriorating or if it’s not safe to stay anymore. This is especially useful for long-term monitoring in critical buildings.
Load Testing Equipment
When you create a heavy structure like multi-storied building, bridge etc., you need to be sure that it’s strong enough to bear the load properly. Load tests apply pressure to structural components to evaluate their load-bearing capacity. At Procon Tech Services, we have modern load testing equipment for testing any structure, says the roof waterproofing Kolkata engineer.
Magnetic Particle Testing
Used primarily on steel structures, this tool helps detect surface and near-surface flaws in metals. By applying magnetic particles to the surface, engineers can locate cracks that might not be visible to the naked eye, ensuring the strength of steel components.
Concrete Resistivity Meter
This measures the electrical resistance of concrete, which is closely linked to its durability. High resistivity indicates low moisture and reduced corrosion risk in reinforcing steel, making this tool essential for assessing the lifespan of concrete structures.
Concrete Core Test
When assessing the strength and quality of hardened concrete, a core test is essential. Cylindrical concrete samples are extracted and tested to determine compressive strength, density, and other properties. This destructive test provides accurate data for detailed structural analysis.
Concrete Carbonation Test
This test evaluates the depth of carbonation in concrete, which can affect reinforcement steel by increasing its susceptibility to corrosion. Using a phenolphthalein solution, engineers can visually measure carbonation depth and assess the durability of the structure.
Concrete Sulphate and Chloride Content Test
Concrete Sulphate and Chloride Content Test Sulphate and chloride content in concrete are critical factors influencing durability and reinforcement steel corrosion. This chemical test determines the presence of harmful ions, enabling engineers to evaluate long-term risks and recommend protective measures.
Well, there are several other tests that we need to perform based on various situations. If you have any query on those tests, get in touch with our senior civil engineers.
