Reveal the true condition
Strength & Surface Integrity
From compressive strength to surface integrity, the CTS-02v4 surfaces the truth hidden near the surface. One device for rapid structural screening.
True Strength
Know the real load-bearing capacity up to 150 N/mm² without drilling a single hole.
Surface Health
Reveal the exact state of aging and degradation before surface delamination or spalling ever appears.
Subsurface Delamination
Find delamination and incipient spalling near the surface.
Early Peeling
Detect aggregate separation at the earliest stage, preventing critical surface failure.
85% Certainty
Comparison on Estimation of Compressive Strength
The shape of strength
The CTS-02v4 captures the exact impact force waveform using a hammer-mounted accelerometer. Every strike produces a wave divided into two distinct phases.
- Phase 1: Surface Compression
The first half of the waveform shows the hammer pushing into the concrete, capturing plastic deformation first, followed by elastic deformation of the surface.
- Phase 2: Elastic Rebound
The second half captures pure elastic rebound. This reveals the true compressive strength, completely unaffected by surface degradation.
By analyzing the ratio between these two phases,
the CTS-02v4 isolates surface aging from delamination near the surface.
