Our Non-Destructive Infrastructure Testing Services
We help in identifying defects, cracks, and weaknesses in structures while keeping them intact and safe for continued use. Our Non-Destructive Infrastructure Testing Services process is cost effective, time saving, and highly efficient for both new and existing structures. Our expertise covers:
Coarse and fine aggregate
Aggregate sand, gravel, crushed stone make up about 60–75% of concrete’s volume and heavily influence its strength, durability, and workability. We conduct gradation analysis to determine particle size distribution, ensuring proper mix quality and reducing cement needs.
Bitumen
Bitumen is the asphalt binder used in road surfaces. Testing ensures correct viscosity,penetration, and temperature sensitivity key for durable pavements.
Paver Block
Paver blocks are tested for compressive strength, density, and flexural and tensile strength to ensure they can withstand loads and wear. The BIS standard dictates these test procedures.
Burnt Clay Building Bricks
Testing involves checking dimensions, uniformity, compressive strength, water absorption, and load-bearing capacity to ensure bricks meet IS norms before use in structures.
Cement (OPC and PPC)
Ordinary Portland Cement and Portland Pozzolana Cement are tested for fineness, setting time, soundness and compressive strength of mortar cubes typically per IS 4031 and IS 269/1489 standards.
Concrete Cube & Concrete Core Tests
These involve casting concrete into cubes or drilling cores from existing structures and testing for compressive strength after curing, commonly at 28 days, to verify structural integrity and compliance.
Design mix of CTB and CTSB layer
Cement Treated Base and Cement Treated Surface Base are pavement layers combining aggregate and cement in precise proportions. Mix design optimizes strength and durability for road bases, though NKMPV’s page doesn’t detail them, they’re standard in pavement engineering.
Design mix of full depth Reclamation (FDR)
FDR reuses existing pavement and sub-base by pulverizing, mixing with cement and water onsite to form a strong base. Design mix tests determine optimal cement content for strength and stability.
Design Mix of Bituminous Layers
● BM: Bituminous Macadam
● DBM: Dense Bituminous Macadam
● BC: Bituminous Concrete
● SMA: Stone Matrix Asphalt
Each requires mix design to ensure correct binder content, gradation, air voids, and compaction for long-lasting pavements.
Steel Bar and Structural Steel
Testing includes checking tensile strength, yield strength, elongation, and bending properties for reinforcement bars (rebar) and other steel ensuring theymeet IS 1786 or IS 2062 standards for structural reliability.
Core cutting of Asphalt Pavements & Concrete
This non destructive method involves extracting cores from existing pavements and evaluating properties like thickness, compaction, and strength. It aids in condition assessment and maintenance planning.
Design Mix of GSB and WMM
● GSB: Granular Sub-base
● WMM: Wet Mix Macadam
These layers form the foundation for paved roads. Mix designs determine proportionsof aggregates and water to achieve strength and compaction for load-bearing capacity
