Concrete Slab Tester TDR2-S

Concrete Slab Tester TDR2-S

The Concrete Slab Tester TDR2-S is a rugged, handheld testing system designed to evaluate the condition, stiffness, and support quality of concrete floor slabs. Using advanced frequency response analysis, it quickly identifies subsurface voids, delamination, and changes in stiffness, making it an essential tool for structural engineers and testing professionals. Housed in a durable ABS casing with waterproof connectors, the system is optimized for use in tough site environments like factories, warehouses, and highway pavements.

Key Features of Concrete Slab Tester TDR2-S

Non-Destructive Testing: Evaluates slab support and load transfer efficiency without damaging the concrete structure.

Dynamic Load Application: Applies controlled impact loads to simulate wheel or equipment loads for realistic performance analysis.

High-Precision Sensors: Equipped with sensitive displacement and load sensors to capture accurate response data.

User-Friendly Interface: Simple controls and digital display for real-time measurements and easy operation in the field.

Data Logging & Analysis: Built-in data acquisition system for storing test results and generating reports.

Durable Construction: Rugged materials and weather-resistant housing ensure long life in outdoor conditions.

Quick Setup Time: Minimal assembly required, allowing tests to begin within minutes of arrival on site.

Fast Voiding Detection: Rapid mapping of slab delamination and sub-base voids.

Real-Time Analysis: On-site measurement of dynamic stiffness and mean mobility.

Comprehensive Software: TPAP-slab software for analysis, contour plotting, and ASCII data export.

Large Storage Capacity: Stores over 700 test results with full metadata.

Lightweight & Portable: Compact form with long-lasting battery (8+ hours).

Complete Solution: Includes impact hammer, velocity transducer, carry case, and optional training.

Applications of Concrete Slab Tester TDR2-S

Subsurface integrity mapping: Quickly locates voids, delamination, or poor bedding beneath concrete slabs.
Dynamic stiffness & mobility analysis: Generates velocity, force, and mobility vs. frequency/time spectra. When coupled with TPAP software, it computes slab dynamic stiffness and mean mobility.
Structural diagnostics: Widely used across infrastructure, industrial facilities, research labs, mining, oil & gas, power plants, and utilities.

Grouting Verification: Monitor effectiveness of slab re-leveling or stabilizing work.

Industrial Floor Evaluation: Assess slab integrity in warehouses and factories.

Highway Pavement Testing: Detect hidden weaknesses under roadways and joints.

Quality Control: Assess slab stiffness before and after remediation work.
