FERROKITS PRODUCT LINE · RETROFIT
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.
YOUR HOME TODAY VS. ARMORED
The same house. A fundamentally different outcome in every threat scenario.
Unarmored
Standard wood siding fails at 80–100 MPH. Roof peels first. Windows blow. Structure compromised.
Armored
Ferrocement exterior handles 200+ MPH. No combustible surfaces to strip. Structure stays intact.
Unarmored
An ember lands on wood siding. It's gone in 12 minutes. It happened in Paradise. In Maui. Every year somewhere new.
Armored
Embers land on ferrocement and die. No ignition point. Non-combustible exterior, period.
Unarmored
Drywall and vinyl siding stop nothing. A standard exterior wall provides zero meaningful resistance.
Armored
Dense ferrocement stops most small-arms fire. Your walls become a hard point in civil unrest scenarios.
Unarmored
Wood-frame home without A/C in summer grid-down: 115–120°F inside. Life-threatening in hours.
Armored
Ferrocement armor adds meaningful thermal mass. Interior temperatures stabilize. 20–30°F cooler without power.
THE PROCESS
01
Structural Assessment
Confirm your existing framing can carry the added load (~8–12 lbs/sq.ft.). Most single-story wood-frame homes qualify without modification.
02
Mesh Anchoring
Galvanized armature anchored to existing framing at 16" centers. No interior work required. Exterior only.
03
Base Coat
Fiber-reinforced mortar, 3/8" thickness. Applied over mesh, worked into all surface irregularities.
04
Intermediate Coat
Polymer-modified mortar, 1/4" thickness. Compressive strength and crack resistance.
05
Finish Coat
Waterproofing and color finish. Can be textured or smooth. Standard stucco appearance or custom finish.
EVERY KIT INCLUDES
Galvanized mesh armature system
Pre-cut to your exterior dimensions. Includes all anchor hardware for wood, masonry, or steel framing.
Three-coat mortar kit
Base coat, intermediate coat, and finish coat — all pre-measured to your square footage. Polymer-modified, fiber-reinforced.
Engineering assessment guide
Load calculation guide and anchor spacing specs. Includes red-flag checklist for structures that need engineering review before installation.
Am-Cor installation manual
Full step-by-step installation sequence with crew sizing recommendations. Remote installation support included.
Material data sheets
For insurance carriers and local building departments. Several carriers offer premium reductions for documented fire-resistant cladding.
Not included: scaffolding, primer coat, paint/stain, window and door trim, any structural reinforcement if required by assessment.
THE MATH
Exostructure Armor
~$95,000
2,000 sq.ft. home · 1,400 sq.ft. exterior
Full Ferrocement Rebuild
~$340,000
2,000 sq.ft. at $170/sq.ft. average
Total Loss + Rebuild
$450,000+
After insurance gap, contents loss, displacement
The armor delivers ~80% of the protection benefit at ~20% of the rebuild cost. This is the most cost-effective path to a hardened home for existing homeowners.
HOW LONG DOES IT TAKE?
Order & Structural Assessment
Week 1–2
Am-Cor reviews your home's exterior dimensions and framing type. Load assessment confirms feasibility. Engineering review arranged if needed.
Kit Fabrication & Shipping
Week 2–6
Mesh armature cut to your exterior spec. Mortar, anchor hardware, and material data sheets crated and shipped.
Mesh Installation
Week 6–7
Armature anchored to existing framing at 16" centers. Exterior only — no interior work required.
Three-Coat Mortar
Week 7–11
Base coat, intermediate coat, finish coat. Each coat requires 5–7 days cure time. Total application: ~3 weeks.
Armored & Complete
Week 11–14
Final waterproofing and finish. Trim details around windows and doors. Full visual inspection. Home is armored.
FREQUENTLY ASKED
Does ferrocement armor work on any type of home?
Most single-story wood-frame homes can accept exostructure armor without structural modification. Two-story homes and older masonry structures require an engineering assessment to confirm the existing framing or foundation can carry the additional 8–12 lbs/sq.ft. of dead load. Am-Cor provides a load assessment checklist with every kit. When in doubt, a structural engineer review costs $500–$1,500 — well worth it before starting.
How much does it cost to armor an existing home?
Exostructure armor starts at $68/sq.ft. of exterior wall surface. For a 2,000 sq.ft. single-story home with approximately 1,400 sq.ft. of exterior wall, that's roughly $95,000–$105,000 installed. Compare that to a full rebuild at $300,000–$440,000, or to losing the home entirely to wildfire or hurricane. The armor delivers ~80% of the structural protection benefit at 20–25% of the cost.
Will exostructure armor save me on home insurance?
Increasingly yes. Several carriers in high-risk states (Florida, California, Louisiana) have begun offering premium reductions for documented fire-resistant exterior cladding systems. Am-Cor provides material data sheets for submission to your carrier. In Florida and California, where insurance costs have risen 40–70% since 2022 — or policies have been cancelled entirely — the savings over 10 years can offset a significant portion of the armor cost.
How long does installation take?
Most single-story homes complete in 3–5 weeks with a trained crew of 4–6. Two-story homes: 5–8 weeks. The three-coat mortar system requires curing time between coats (5–7 days each), which drives the timeline. Kit ships in 4–6 weeks. Total time from order to armored home: 7–12 weeks.
Does exostructure armor require a building permit?
In most jurisdictions, adding cladding to an existing structure requires a permit. This is typically classified as an "exterior wall covering" or "structural cladding" permit — straightforward in most counties. Am-Cor's material data sheets and engineering guide support permit submission. Some jurisdictions expedite permits for fire-resistant or storm-resistant retrofits.
When should I start?
Kit lead time is 4–6 weeks. Installation is 3–8 weeks. Hurricane season starts June 1. Wildfire seasons are extending into year-round events in many regions. Your window to be armored before the next major event is right now. Material costs have risen consistently since 2022 — every month you wait, the price goes up and your readiness date slips.
READY TO ARMOR
A 7–12 week total timeline from order to armored home. If you're ordering today in early 2026, you can be protected before peak season. Every week of delay shortens your window.
