The Difference Matters

Not All "Saferooms" Are Created Equal

When a tornado hits, lab certifications mean nothing. What matters is real-world performance. Only one saferoom has been tested by nature's most powerful force — and passed.

Other Storm Shelters

Lab Tested Only

  • Thin walls with joints and seams
  • Swinging doors that can fail under pressure
  • Pre-fabricated off-site
  • Never tested by an actual tornado
OZ Saferooms

Field Proven

  • 18" thick monolithic concrete — no joints
  • Steel-trapped sliding door (survived F5)
  • Hand-built on your property
  • Survived direct F5 hit — zero damage
Engineered for the Worst

Why OZ Stands Alone

FEMA commissioned OZ to develop the aboveground monolithic concrete saferoom because traditional storm shelters weren't enough.

18"

Reinforced Ceiling

One and a half feet of solid reinforced concrete overhead — not the thin shells others call "protection."

5K

PSI Concrete

High-strength concrete with a continuous rebar cage through floor, walls, and ceiling.

0

Joints or Seams

Monolithic construction means no weak points. The entire structure is poured as one solid piece.

100%

On-Site Built

Formed and poured on your property by hand. No heavy equipment damaging your yard.

∞

Fully Ventilated

Exceeds all ventilation standards. Breathe easy even during extended shelter time.

Sliding Door

Our steel-trapped sliding door design survived the direct F5 hit. Swinging doors fail under pressure.

Real-World Proof

The Only Saferoom to Take a Direct Hit from an F5 Tornado

On May 20, 2013, one of the most powerful tornadoes in recorded history struck Moore, Oklahoma. Inside an OZ Saferoom, a family survived with zero structural damage to their shelter.

This wasn't a lab simulation. This was nature's ultimate test — 200+ MPH winds, massive debris impacts, complete home destruction. The OZ Saferoom stood. The family walked out unharmed.
