Every high-performance concrete floor is only as reliable as the empirical engineering data behind it. Gangadhar Concrete Solution conducts comprehensive, non-destructive and destructive testing in compliance with UK TR34 (4th Edition), ASTM E1155, and DIN 18202 standards — giving facility owners, structural consultants, and warehouse operators independently verified proof of floor quality.
From pre-pour subgrade Plate Bearing Tests (PBT) that establish foundation modulus to post-pour continuous digital floor profilometer surveys for FM1/FM2 free-movement and DM1/DM2 defined-movement aisles, our chartered engineering audits provide complete compliance documentation, warranty validation, and official handover certification.
Applicable Operations & Equipment
Newly constructed warehouse slabs, VNA warehouse racking installations, ASRS high-bay logistics hubs, and pre-handover due diligence for institutional developers.
Digital Floor Profiler Surveying (TR34 FM & DM Standards)
Using state-of-the-art continuous digital floor profilers and robotic survey instruments, our certified technicians measure floor elevation profiles continuously along the exact wheel paths of Material Handling Equipment (MHE). The survey calculates Property E (Levelness), Property F (Flatness), Property Z, and d2Z with millimetric precision.
Engineering Advantages
- Generates full digital topological reports and heat maps of floor levelness
- Calculates exact compliance percentage for FM1, FM2, FM3, DM1, and DM2 classes
- Identifies localized high/low spots for precision micro-grinding corrections
- Third-party chartered engineer certificate accepted by global logistics tenants
Ideal Applications
- Very Narrow Aisle (VNA) racking corridors
- Reach-truck free-movement storage zones
- ASRS automated warehouse shuttle tracks
Geotechnical Plate Bearing & Sub-Base Load Testing
Before a single cubic metre of concrete is placed, our engineering team conducts in-situ Plate Bearing Tests (IS 1888 / DIN 18134 / BS 1377) across the compacted sub-base. This verifies the modulus of subgrade reaction (k-value) and deformation modulus (Ev2/Ev1) to ensure the foundation can support heavy static point loads without settlement.
Engineering Advantages
- Confirms sub-base compaction meets design load bearing requirements (CBR / k-value)
- Prevents differential settlement, slab rocking, and subgrade-induced cracking
- Provides certified soil bearing data for structural slab thickness calculations
- Validates contractor earthwork compaction before expensive concrete pours
Ideal Applications
- Pre-pour warehouse sub-base and WMM / GSB layer testing
- Heavy manufacturing machine foundation pads
- External concrete apron and truck loading dock yards
Hardened Concrete Core & Non-Destructive Quality Audits
Post-curing quality assurance includes non-destructive Rebound Hammer tests (IS 13311), core extraction and compressive strength testing (IS 516 / BS EN 12504), surface abrasion resistance testing (BS EN 13892-4), and moisture vapor emission rate (MVER) testing per ASTM F1869.
Engineering Advantages
- Verifies characteristic compressive strength against design grade (M30/M35/M40)
- Quantifies surface abrasion resistance classification (Special, AR1, AR2, AR3)
- Tests moisture vapor emission rates before applying epoxy coatings or sealers
- Provides immutable forensic quality audit records for insurance and structural warranties
Ideal Applications
- Final building completion certificates and client handovers
- Dispute resolution and structural performance validation
- • TR34 4th Edition Code
- • ASTM E 1155 Levelness
- • DIN 18202 Precision
- • EN 10025-2 Duraplate
Key Benefits
- Independent, third-party verification and chartered engineer sign-off
- Documented FM1/FM2 and DM1/DM2 compliance certification per TR34 (4th Edition)
- Continuous digital floor profiling eliminating manual optical leveling discrepancies
- Pre-pour geotechnical plate bearing tests (PBT) verifying subgrade reaction (k-value)
- Guarantees reach truck stability, prevents mast sway, and protects MHE warranties
Target Facilities
- New warehouse, logistics park, and industrial floor handovers
- Very Narrow Aisle (VNA) facilities requiring DM1/DM2 certification up to 13m height
- High-bay racking installations requiring MHE vendor warranty compliance
- Pre-installation structural audits for automated guided vehicles (AGVs) and AMRs

The 5-Phase Execution & Quality Lifecycle
Every GCS concrete floor undergoes a strict 5-stage engineering workflow from pre-pour sub-base testing to final TR34 chartered certification.
Phase 1: Pre-Survey & Sub-Base Benchmark
Our chartered engineering team conducts a thorough site level survey and plate bearing test (1 test per 2000m² plus 2 additional benchmarks). We verify sub-base compaction and slope tolerances before any concrete arrives.
