Rebound Hammer Test & Concrete Quality Check Services in Chennai.‍

Know Your Building’s True Strength.

Is the concrete weak? Are there hidden cracks? Our Non-Destructive Testing (NDT) reveals the hidden reality of the structure without breaking a single brick. Protect your investment today.

Scientific NDT Testing (Non-Destructive Testing) to Assess Building Strength & Check Concrete Quality Without Breaking Concrete.

Is your building actually strong, or just looking strong? You don't need to break your pillars or damage your flooring to check your building's safety. At Structural Sense India Pvt Ltd, we use advanced NDT Testing Services to scientifically measure the strength of your concrete.Whether you are buying a 20-year-old property and need an Old Building Stability Check, or you are a contractor needing a Concrete Compressive Strength Test for a new site, our engineering team provides precise, data-backed reports.

When Do You Need a Building Strength Assessment?

1. Buying an Old Property : Before you invest crores in a resale flat, get an Old Building Stability Check. A simple Rebound Hammer Test can reveal if the concrete has weakened over 20+ years.

2. Visible Structural Distress: If you see spalling (concrete falling off) or deep cracks, an UPV Test helps determine if the damage is structural or superficial.

3. Industrial Load Testing: For factories in Oragadam or Sriperumbudur, we conduct Slab Load Testing to certify if your floor can support heavy new machinery.

Rebound Hammer Test (Surface Hardness Check)

Best For: Homeowners, Concrete Quality Checks, & Quick Audits.
What it is: The Rebound Hammer Test is the most widely used method to estimate the compressive strength of concrete. We use a calibrated Schmidt Hammer to impact the concrete surface. The rebound value gives us an immediate indication of the surface hardness and concrete grade (e.g., M20, M25).
Why use it? It is a fast, affordable, and non-invasive way to check building stability without leaving marks.

Ultrasonic Pulse Velocity (UPV Test)

Best For: Detecting Hidden Cracks, Honeycombs, & Voids.
What it is: The Ultrasonic Pulse Velocity Test sends ultrasonic sound waves through your concrete columns or beams. If the wave speed slows down, it detects internal defects, concrete voids, or cracks that are invisible to the naked eye.
Why use it? Essential for verifying concrete homogeneity and ensuring your structure is solid from the inside out.

Half-Cell Potential Test (Corrosion Analyzer)

Best For: Coastal Areas (Chennai), Old Buildings, & Industrial Structures.
What it is: Rusting steel expands and cracks concrete from the inside. The Half-Cell Potential Test measures the electrical potential of the rebar to detect the probability of corrosion before any cracks appear on the surface.
Why use it? It is the only way to predict if your building will have severe spalling or corrosion issues in the next 2-5 years.

Rebar Scanning & Cover Meter Survey

Best For: Renovation Projects, Architects, & Safety Audits.
What it is: Planning to drill a wall or extend a balcony? Our Rebar Scanning service locates the exact position, depth, and diameter of hidden reinforcement bars (rebars).
Why use it? Prevents accidental damage to structural steel during renovation and helps in structural auditing of old buildings.

Concrete Core Cutting Test (Semi-Destructive)

Best For: Legal Verification, Third-Party Quality Assurance.
What it is: When 100% accuracy is required, we perform a Concrete Core Test. We extract a cylindrical sample from the structure and test its crushing strength in a lab.
Why use it? It is the "Gold Standard" for proving concrete strength in disputes or final safety certifications.

Frequently Asked Questions

What is the cost of a Rebound Hammer Test in Chennai?
‍A: Pricing depends on the number of points tested. It is generally the most affordable NDT testing service available for residential buildings compared to destructive methods.
Can you check concrete strength without breaking it?
A: Yes. Using Non-Destructive Testing (NDT) methods like the Rebound Hammer and UPV Test, we can estimate concrete compressive strength with 85-90% accuracy without damaging your structure.
Is the Rebound Hammer Test accurate for old buildings?
‍A: For buildings older than 15 years, the surface is often carbonated (harder). We recommend combining it with a Carbonation Depth Test and Half-Cell Potential Test for a reliable structural audit.

Structural Design & Engineering

We create safe, economical structural plans tailored to your specific needs. Whether it is a luxury villa in Anna Nagar or an industrial shed in Ambattur, our designs optimize material usage to save costs while strictly adhering to IS Codes and safety standards.

Structural Damage Inspection & Assessment

Evaluation of cracks, deflection, distress patterns and member response to understand structural behaviour and identify risk. Provides clarity on structural adequacy and engineering direction for safe decision-making.

Structural Strengthening & Repair

Engineering strategy for restoring or increasing structural capacity, stiffness and durability based on behaviour, condition and load demand. Supports safe strengthening, retrofitting and lifespan extension without unnecessary intervention.

Stability Certification

Independent verification of structural stability, load performance and compliance for approvals, occupancy and documentation. Confirms building safety and fulfils regulatory requirements with engineering-backed certification.

NDT Testing Services

Don't guess your building's safety—measure it. OurNDT Testing Services reveal hidden voids, corrosion risks, and actual concrete grade using advanced sensors. Ideal for pre-purchase inspections and quality control.
