What We Do
Underground bunker installation, CBRN filtration, off-grid power, and blast-rated construction for Montana properties.
Our Services
You've ordered a bunker but don't know how to excavate safely or place it securely. We manage excavation, placement, anchoring, backfilling, and final system testing so your shelter is ready when you need it. All work follows OSHA excavation protocols with proper shoring and drainage. Site preparation includes grading and perimeter drains to prevent water issues. We verify all life-support systems before handoff.
Nuclear EMP or solar storms could destroy unprotected electronics when you need them most. We build continuous Faraday cage enclosures around your bunker's critical systems, seal all cable penetrations, and verify shielding continuity with testing equipment. Conductive mesh layers block electromagnetic pulses while surge protectors handle power spikes. Every penetration point is sealed to prevent EMP entry. Continuity testing confirms no gaps in shielding before final handoff.
You're buying land or planning a bunker but don't know nearby hazards or if your soil supports underground construction. We analyze site-specific risks including wildfires, earthquakes, flooding, and proximity to military bases or urban centers. Geological surveys assess soil stability, water tables, and seismic loads. Proximity threat mapping identifies hazards within 50 miles. Risk mitigation planning recommends bunker depth, shielding levels, and structural requirements. You get a detailed report for permitting and design decisions.
You need a bunker sized for your family with specific room layouts and threat protection levels. We design and build custom underground bunkers using ICF concrete or welded steel construction. Foundation work includes perimeter drains and waterproofing membranes. Reinforced walls meet Montana seismic loads with structural engineering stamps. Interior finishing includes electrical rough-in, plumbing, HVAC ducts, and wall surfaces ready for your equipment. All work follows building codes with inspections at each phase.
You have a basement or safe room but it won't withstand serious threats like overpressure, radiation, or airborne contaminants. We reinforce existing walls with steel or concrete layers, install blast-rated doors with manual overrides, and integrate CBRN air filtration with overpressure blowers. Structural engineering verifies load-bearing capacity before reinforcement. Waterproofing membranes and perimeter drains prevent moisture intrusion. Off-grid power systems run filtration and lighting for extended stays. All work minimizes disruption to your home's living spaces.
You need blueprints that account for your site's soil conditions, water table, and seismic loads while fitting your family size and threat concerns. We develop custom floor plans with room layouts optimized for long-term stays. Structural engineering plans specify concrete thickness, rebar spacing, and blast ratings stamped for Montana building codes. 3D renderings show ventilation paths, power routing, and equipment placement. Site-specific adaptations address drainage, access points, and concealment. All drawings are permit-ready with material specifications and construction sequences.
You're worried about nearby explosions from accidents, attacks, or military activity that could level ordinary buildings. We construct blast-resistant shelters with reinforced concrete walls rated for specific overpressure levels. Blast doors are tested to withstand shockwave forces without failing or blowing inward. Structural pressure testing verifies the entire shelter can handle explosive events. Overpressure protection includes venting systems that equalize pressure spikes. All work meets depth and shielding requirements for your threat level.
After a nuclear event, fallout radiation can persist for weeks and penetrate ordinary structures. We construct shelters with concrete walls thick enough to attenuate gamma radiation to safe levels. Lead lining adds extra shielding at critical points like doors and ventilation penetrations. Dosimeter integration lets you monitor radiation exposure inside the shelter. Attenuation testing verifies shielding effectiveness before handoff. Proper depth and earth coverage provide additional protection. All construction follows radiation shielding calculations for your threat scenario.
Airborne contaminants like nerve agents, pathogens, or radioactive particles will enter your bunker through cracks and ventilation unless you have positive pressure and multi-stage filtration. We install NBC filtration systems with HEPA H13 filter banks that capture 99.97% of particles and activated carbon filters that remove chemical vapors. Overpressure blowers maintain positive pressure so contaminated air can't seep in. Filter change protocols let you swap filters safely during events. All systems are tested for airflow and pressure before handoff.
When the grid goes down, your bunker's air filtration, lighting, and communication systems stop working unless you have independent power. We design off-grid systems with solar arrays sized for Montana winters, 48V battery banks that store days of power, and generator backup for cloudy periods. Load balancing distributes power to critical systems first. Charge controllers prevent battery damage. All wiring and panels are EMP-shielded. System testing verifies runtime under full load before handoff.
High water tables and heavy rains cause groundwater to penetrate underground structures through cracks, joints, and porous concrete. We apply rubberized exterior membranes to all walls and floors before backfilling. Perimeter drains with gravel beds channel water away from the bunker. Joint sealing with polyurethane or epoxy prevents leaks at wall-floor connections. Interior moisture barriers add a second layer of protection. All work is tested for leaks before final backfill.
Your bunker sits unused for years but needs to work perfectly when a crisis hits. Filters clog, batteries lose charge, seals dry out, and cracks develop. We perform annual system checks that test air filtration flow rates, verify power system output and battery health, and scan walls for structural cracks. Filter replacements are scheduled based on usage and age. Power diagnostics catch failing components before they leave you in the dark. Structural integrity scans use thermal imaging to find hidden moisture or damage.
Your existing bunker has developed cracks that let water in, air systems that no longer work, or structural settling that compromises protection levels. We inject epoxy into cracks to restore waterproofing and structural integrity. Water damage mitigation includes new drainage, membrane repairs, and interior drying. Panel replacement addresses rusted or damaged steel components. System component repair fixes air filtration, power, and door mechanisms. All repairs are tested to verify they restore original protection levels.
