Client Challenge:
In a high-security commercial unit, a client faced a major challenge: the controlled demolition of a 12x12 ft reinforced bank vault. The structure was heavily fortified with a 7 mm internal steel lining, steel stiffeners, metal angles, and fiber-reinforced concrete. To make things even more complex, the vault included a 2-ton steel door with a 16 mm reinforced base floor.
This was not just a demolition—it was a surgical removal requiring precision tools, engineering expertise, and zero collateral impact on surrounding units.
Solution: SANG Diamond Tools' Advanced Concrete Cutting Technology
To meet this challenge, SANG Diamond Tools deployed a suite of their high-performance products:
1. Concrete Wire Saw (30 kW Electric System)
Ideal for cutting thick, heavily reinforced concrete and embedded steel
Powered by an external generator to ensure stable operation on-site
Enabled low-vibration, dust-free, and noise-controlled cutting
2. Reinforced Concrete Saw Blade
Used in wall sawing and walk-behind saws
Delivered clean, segmented cuts for precise dismantling
Designed specifically for fiber and steel-reinforced structures
Execution Strategy: Step-by-Step Controlled Demolition
Phase 1: Technical Assessment
Before any cutting, our specialists performed a comprehensive structural analysis, evaluating:
Wall thickness
Reinforcement density
Vault door composition
This ensured a safe, efficient demolition plan with minimal risk.
Phase 2: Multi-Tool Deployment
Wire Sawing: Applied to vault walls and the massive steel door. Segmented the door into manageable parts for safe extraction.
Wall Sawing: Used for vertical and thick concrete segments.
Walk-Behind Saw: Provided high-precision cutting on the vault floor.
Phase 3: Clean Dismantling
Over 15 working days, the vault was cut and removed piece by piece, without the use of jackhammers or impact tools. This method:
Prevented shock loads to adjacent structures
Eliminated dust and noise pollution
Preserved surrounding commercial integrity
Results & Impact
Zero structural damage to neighboring units
No disruption to commercial activities nearby
Safe removal of one of the most fortified vaults using only diamond cutting methods
Reinforced SANG Diamond Tools' position as a leader in advanced concrete cutting solutions
