Slab Load Testing

Proof loading of RCC floors & slabs

To verify the load-bearing capacity of newly constructed or aged floor slabs — especially when concrete strength is doubtful, design grade is unverified or change of usage requires higher loads.

What We Do

  • Proof load test (1.25 × design load)
  • Deflection measurement at mid-span
  • Recovery percentage after unloading
  • Crack monitoring during & after load
  • Distributed load using water bags / sandbags
  • Compliance with IS 456 Clause 17
  • Load test of cantilevers
  • Industrial floor uprating test

Methodology

Slab inspection & instrumentation → load increment in 4 stages (25%, 50%, 75%, 100%, 125%) → 24-hour sustained load → deflection recording → controlled unloading → 24-hour recovery observation → analysis per IS 456 Clause 17 → pass/fail certification.

Deliverables & Outcomes

We deliver comprehensive reports and data that guide your project planning and decision-making.

  • Slab Load Test Report
  • Load vs deflection graph
  • Recovery analysis chart
  • Crack monitoring records
  • Pass/Fail certification
  • Strengthening recommendations (if needed)
