Hard Rock Excavation
Bedrock breaking in congested urban zones
Overview
Technical Capability
Excavating tough bedrock, quartzite, and granite formations. RPC uses mechanical breakers and chemical expansive mortars to fracture rock without blasting hazards.
Key Applications
- Deep basement bedrock breaking in South Delhi
- Metro line tunnel shaft excavation
- Bedrock trenching for heavy pipeline systems
- Cracking bedrock adjacent to active structures
Execution Approach
We drill holes using DTH rigs, pour chemical expansive mortars to fracture the bedrock, and clear the fractured rock with heavy breakers.
Safety & Compliance Parameters
Non-blasting rock excavation technology, DTH drilling rigs, certified operators.

Frequently Asked Questions
No, explosive blasting is restricted in metropolitan areas. We use silent chemical cracking and hydraulic hammers instead.
We excavate quartzite, granite, sandstones, and thick concrete structures.
