  • Drain Raft Concrete NDT Assessment at JK Tyre
By: Prabhat Bhargava

2 January, 2026

BBAPL conducted Non-Destructive Testing (NDT) on the drain raft structure of JK Tyre & Industries Ltd. This testing was done to check the in-situ compressive strength, surface hardness, and uniformity of concrete installation.

This critical assessment ensures the foundational drainage system meets design specifications and delivers long-term structural performance.

Drain Raft NDT Assessment

Why Drain Raft Testing Matters

The drain raft is an essential element of foundation systems. It is charged with the responsibility of controlling the water flow and eliminating the development of hydrostatic pressure. Any weakness in the structure may result in:

  • Differential settlement and instability of the foundation.
  • Moisture corrosion and seepage.
  • Problems with long-term durability.
  • Remedial interventions are expensive.

Our NDT practice ensures these risks are identified early on, which enables quality management proactively.

Our Testing Methodology

Testing Parameter Method Used Purpose
Compressive Strength Rebound Hammer Test Assess in-situ concrete strength
Surface Hardness Schmidt Hammer Verify concrete quality consistency
Uniformity Analysis Multi-point Testing Detect weak zones across the raft

Testing Process:

  • Strategic Location Selection: Multiple test points identified across the drain raft surface
  • Calibrated Equipment Deployment: Schmidt Rebound Hammer calibrated to IS standards
  • Systematic Data Collection: Methodical readings recorded at each location
  • Strength Correlation Analysis: Rebound values converted to compressive strength
  • Comprehensive Reporting: Digital documentation with QR validation
