KEY DELIVERABLES6 Formal Outputs
CODE COMPLIANCEIS:1892 & IRC ALIGNED

Investigation Mandate

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 Deliver On Site

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

Field & Laboratory 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.
