Structural Earthing System – Engineered for Indian Buildings & Infrastructure (ARK Make by DFMHUB)
Electrical safety failures in buildings are not caused by equipment alone — over 65% of electrical faults in India are directly linked to inadequate earthing and grounding systems (CEA safety audit observations, 2023).
In a country with high soil resistivity variation, dense urban construction, monsoon-driven moisture cycles, and rapidly increasing electrical loads, conventional pit earthing methods are no longer sufficient.
The ARK Make Structural Earthing System by DFMHUB is engineered as a permanent, foundation-integrated earthing solution, designed specifically for Indian soil conditions, RCC structures, and statutory compliance requirements.
What Is a Structural Lightning Protection System?
A Structural Earthing System is a foundation-based earthing method where earthing conductors are permanently bonded to RCC reinforcement steel, creating a large-area, low-impedance earthing electrode embedded within the building structure itself.
Key Engineering Characteristics:
- Uses RCC rebars as natural electrodes
- Fully concealed & maintenance-free
- Extremely stable resistance values
- Long service life (50+ years)
The ARK Make system by DFMHUB enhances this concept using engineered copper-bonded conductors, tested clamps, and documented bonding methodology.
Why Structural Lightning Protection Is Critical?
High-rise buildings, industrial plants, substations, and solar installations are vulnerable to direct lightning strikes. Structural LPS ensures:
- Concealed protection within RCC
- Reduced corrosion risk
- Enhanced safety and structural integrity
- Compliance with international standards
