YOUR HOUSE IS A COFFIN. HERE'S THE FIX. · AM-COR FERROCEMENT KITS
Build YourBug-In Fortress.
You've been watching the news for 3 years. You've done nothing. The grid is tight. The heat is coming. Backyard bunkers, SHTF-ready homes, and exostructure armor — from $89/sq. ft. Stop waiting. Start building.
THE WINDOW IS CLOSING
Stop Pretending It Won't Happen
NOAA. FEMA. NERC. They don't agree on much. They agree on this: 2026 is different. The people who build now sleep at night. Everyone else is hoping for the best. Hope is not a survival strategy.
PICK YOUR THREAT
Every SHTF Scenario Has a Right Answer.
Grid-down is not nuclear. Wildfire is not hurricane. Each threat has a specific, buildable answer. Find yours — then use the Planner to price it in 60 seconds.
Grid Goes Down
The grid fails. 105°F outside. Your wood-frame house becomes an oven in 4 hours. People die. A ferrocement shell stays 20–30°F cooler with zero power. Stop depending on a system that NERC says has no buffer left.
Run the Planner. Pick your size. Get your number in 60 seconds.
Super Heatwave
Sustained 110°F+ turns standard homes into kill zones. Ferrocement thermal mass buys 24–48 hours with zero power. Add a subterranean room: 55°F refuge while everyone else is cooking alive.
This is solvable. Use the Planner below. Takes 2 minutes.
Nuclear Fallout
10–12" ferrocement walls. Sealed ventilation. Underground bunker. That's your 14-day window. The 7-10 rule: fallout drops to 1/1000th of peak after two weeks. Two weeks. You just need to survive two weeks.
A Baby Bunker kit ships in 6–8 weeks. Order now — that math matters.
Bug-In Fortress
Roads gridlock in 6 hours. Your bug-out plan fails. The smart move: make your home the place everyone else wants to run TO. Non-combustible. 200+ MPH rated. Ballistic. Thermally independent.
Price the exostructure armor for your home right now. It's faster than you think.
Hurricanes & Floods
Category 5 hits. Your neighbors' roofs are airborne. Your ferrocement shell is still standing. Zero combustible surfaces. 200+ MPH rated. You're not evacuating. You're watching from inside with the lights on.
Armor retrofit ships in 4–6 weeks. Storm season starts in June.
Wildfire
An ember hits your roof. A wood house is gone in 12 minutes. It happened in Paradise. In Maui. It's happening every year in new places. Ferrocement exterior: embers die on contact. Retrofit without demolition.

What are you building?
Your Walls Are
Made of Sticks.
Most American homes are wood-frame boxes. Kindling. In a grid-down heatwave, they kill people. In a wildfire, they're gone in 12 minutes. FerroKits replaces that with monolithic ferrocement — the same material used in disaster-proof construction worldwide.
Not a bunker disguised as a home. A home that's finally built for the real world. Pre-engineered kits deploy rapidly — high-strength shells against fire, kinetic impact, extreme heat, and grid instability — at a fraction of traditional construction cost.
Three Products. One Decision. Make It.
2026 summer production slots are filling. If you're serious about being ready before hurricane season, the window to order is now.
Standard Custom Home Kits
Not a bunker with a roof. A real home — monolithic ferrocement shell, pre-engineered framework — that happens to survive what kills everyone else's house. Grid-down. Wildfire. Category 5. Built in.
⏱ Kit ships 8–12 weeks · Installation 4–6 weeks
Configure Your Shell →Baby Bunker / Mini Shelter
Subterranean or semi-submerged vault for 2–8 people. Non-combustible. Radiation-attenuating. Discreet. Add one to an existing property in weeks. The difference between a 14-day survival window and hoping for the best.
⏱ Kit ships 6–8 weeks · Install in ~2 weeks
Secure Your Bunker →Exostructure Wall & Roof Armor
Already own a home? Don't demolish it. Armor it. Ferrocement panels applied to your existing structure — no foundation changes, no rebuild. Ballistic. Fire-rated. Storm-hardened. Fastest path from vulnerable to protected.
⏱ Kit ships 4–6 weeks · Retrofit 1–2 weeks

We Have Answers. Build First, Regret Nothing.
How much does a backyard bunker cost to build?
A ferrocement backyard bunker starts at $180/sq ft with Am-Cor kits. A standard 400 sq ft baby bunker runs approximately $72,000 — fraction of what custom poured concrete or steel runs. Underground installation and ventilation are additional. Use the Planner above to get your specific number in under 2 minutes.
What's the best bunker material for nuclear fallout?
Ferrocement at 10–12" wall thickness provides meaningful gamma shielding. Combined with sealed ventilation and 14-day supplies, this follows the 7-10 rule: after two weeks, fallout drops to 1/1000th of peak. Ferrocement outperforms standard concrete at the same weight. The Baby Bunker kit is purpose-built for this. It ships in 6–8 weeks. Order before you need it.
Is it better to bug in or bug out during a SHTF event?
For most preppers, bugging in wins. Roads gridlock in 6 hours. Your home has your water, your stockpile, your weapons. The one variable: can your home take the hit? A ferrocement shell or exostructure armor turns it into a hard target — genuinely safer than anywhere you could drive to. This is solvable. Run your threat through the Planner.
How much does it cost to wildfire-proof or hurricane-proof an existing house?
Exostructure armor starts at $68/sq ft — no demolition. For a 2,000 sq ft home, roughly $136,000 to get 200+ MPH wind resistance, 2-hour fire rating, ballistic hardening. Compare that to a total rebuild after a loss. Kits ship in 4–6 weeks. Hurricane season starts June 1. The math writes itself.
