Semi-Destructive Testing

At Booshnam Associates Pvt. Ltd., we employ Semi-Destructive Testing (SDT) to bridge the gap between non-invasive evaluation and comprehensive material analysis.

These methods involve localized, minimal intrusion—such as small core extractions—providing highly reliable, direct physical data without compromising the overall structural integrity.

Our precise SDT approach is essential for accurate compressive strength determination, carbonation depth checks, and chemical composition profiling in aging or damaged structures.

Our SDT Process

Site Preparation
Phase 01

Site Preparation

Identifying optimal testing locations using rebar locators to avoid structural damage.

Controlled Sampling
Phase 02

Controlled Sampling

Extracting concrete cores using specialized, vibration-free diamond drilling equipment.

Lab Assessment
Phase 03

Lab Assessment & Repair

Testing samples in our NABL lab and immediately repairing the core holes on-site.

Semi-Destructive Testing

Semi-Destructive Testing (SDT) bridges the gap between NDT and fully destructive testing. These methods provide direct, highly reliable measurements of concrete properties with only minimal, easily repairable surface damage.

Our SDT services are essential for accurate structural assessment, allowing engineers to reliably calculate the exact strength and chemical composition of the existing concrete.

SDT Core Sampling Laboratory Analysis

Advantages of SDT

01
Direct Data: Provides actual in-situ compressive strength rather than estimated surface hardness.
02
Minimal Intrusion: Small core sizes ensure structural safety is never compromised.
03
Chemical Profiling: Enables laboratory analysis for carbonation, chloride, and sulfate attacks.
04
Calibration: Used to calibrate and cross-verify results obtained from Non-Destructive Testing (NDT).
05
Dispute Resolution: Offers definitive proof of material quality in cases of construction disputes.
