Protecting Your Underground Teams Is Our Expertise
From the initial audit through to full integration, our engineering and design office supports project owners and contractors across three essential areas: compliant emergency refuge chambers, self-contained sanitation facilities, and optimized ventilation systems.
Sub’Roca, Your Technical Partner
At Sub’Roca, technical expertise comes before the product. Before recommending any equipment, we assess your site, risks, and regulatory constraints. This approach has enabled us to contribute to some of the largest underground projects worldwide.
Our engineering and design office supports project owners, engineering firms, and underground construction companies at every stage of their projects: from preliminary airflow studies and integration with tunnel boring machines to the preparation of specific safety plans and the training of field teams.
Refuge Integration Studies for Underground Environments
For every new underground project, emergency refuges must be adapted to specific site constraints. Our expertise ensures optimal integration and full compliance with safety standards.
Our studies cover:
Refuge Sizing — Capacity calculations based on workforce size and exposure duration
TBM Integration — Installation on tunnel boring machines (TBMs) for tunnel projects
Mining Installation — Adaptation of the MINE SHELT’AIR to underground constraints
Accessibility & Exits — Compliance with evacuation and accessibility standards
Regulatory Compliance — Safety plans and regulatory compliance
Auxiliary Systems Integration — Integration with ventilation, sanitation, and power supply systems
From Audit to Delivery
A structured four-step approach to ensure that every Sub’Roca solution is perfectly adapted to your site and constraints.
01
Needs Assessment
Every underground project is unique. Our engineers analyze your environment, operational constraints, and the specific risks of your site to determine your actual requirements for operator protection.
02
Feasibility Study
Our engineering and design office assesses the technical constraints, project schedule, and risk scenarios to design a solution that is perfectly integrated into your environment. This approach ensures effective protection tailored to your operations.
03
Solution Recommendation
Following the study, we recommend the most suitable solution. Each recommendation is designed to meet your operational requirements while optimizing the safety of your teams.
04
Manufacturing & Delivery
Our equipment is designed and manufactured in France by our teams, then thoroughly inspected before shipment. We ensure delivery within your required timeframe so that your installation can be operational quickly on your site.
