Ballistic sliding bomb shelter door

Underground bomb shelter kit
with detailed installation manual
and an engineered pressure rating

Building an underground shelter? We have everything you need right here.

Bomb shelter kit being builtThis bunker kit provides all of the critical components of a true steel reinforced concrete underground bunker. You purchase the heavy (expensive to ship) concrete and blocks locally. Then you follow the comprehensive installation manual and build your bunker.

We fabricate all of the critical components and ship them to your shelter site by flatbed truck. We can include the pre-cut and formed rebar, or you can procure it locally.

You decide the options you want with this kit: blast hatch, blast door, an airlock, and more! For a quotation on the exact shelter kit you need, contact our sales manager at 541-459-1806 or sales@americansaferoom.com.

Rivets on a bomb shelter door

Shelter kit layout
What sets this system apart is the integrated design and manufacture process that decreases the cost and build time while increasing the strength and features. The wide flange steel beam trusses allow you to pour the concrete ceiling without erecting temporary cribbing. The steel trusses stay embedded in the ceiling giving additional strength over and above what rebar normally provides.

The trusses and the rebar are what give this shelter kit its certified blast load rating of 20.7 PSI. See page 58 of the manual for the professional engineers certificate showing this rating. This is a true blast load rating. The weight of the ceiling, the backfill, and even a vehicle parked on top were added in before the blast load was calculated.

We also manufacture the blast doors and hatches, blast valves, ventilation pipes, and a NBC filter - every critical component you need for your shelter. If you are planning a shelter, be sure and see our page on principles of shelter design.

Series 400 shelter kit
This series of pictures shows a series 400 shelter kit with an optional blast door and an extra ventilation pipe to provide ventilation for a toilet. We also supplied the pre-cut and formed rebar with this shelter kit.

Shelter kit layout - trussesThese are the trusses laid out with the hatch ladder on top. Note the last two trusses are connected. These are the riser trusses.

 

Shelter kit layout - trusses and hatchThis is the riser hatch on the riser trusses with the rebar in the background.

 

Shelter kit layout - riser trussesThis is the riser truss pair. This pair of trusses are welded together and form a pallet for the rest of the trusses to be shipped on. Note the "tunnel" that the riser sits on is a form. The concrete is poured all around it and the riser hatch is mounted on top.

 

Shelter kit layout - truss closeupHere is a detail of a truss showing the holes we punch for the rebar as well as the two small holes for the form board bracket.

 

Shelter kit layout - rebarThis is the pre-cut and formed rebar. It is cut, formed, counted, labeled, bundled, and tagged.

 

Shelter kit layout - blast doorThis is the single leaf blast door that was shipped with this kit.

 

Shelter kit layout - hatchThis is the riser hatch. It is an older style without the internal cam latch. All hatches we build now have a cam latch to suck the blast lid down onto the seal on the riser lip.

The emergency escape jack has not been installed. The two ears on the right side of the blast lid accept the top end of this three ton jack.

Note the deadbolt lock mounted on the blast lid right above the pull handle, the EPDM seal around the top lip and the wide angle viewer ports on each side, just below the top lip.

For more information on our hatches, see the flat blast hatch and the riser blast hatch pages.

 

Shelter kit layout - ventilation pipesThese are the ventilation pipes. One air intake, one air outflow, and one septic drain ventilation pipe. All ventilation pipes need a blast valve to protect the occupants from a nearby detonation.

Also shown are the angle brackets, the form board brackets, the deadbolt cap for the riser blast hatch, the electrical, water, and septic penetrations as well as the bottom struts for the ladder.

 

Shelter kit layout - ventilation pipes ready to shipThese are the ventilation pipes strapped to the blast door for shipping.

 

Shelter kit layout - trusses ready to shipThese are the trusses and ladder banded on top of the riser truss pair for shipping. The rebar is banded to the top of this and everything is loaded onto a flatbed truck. The bands can be sequentially cut and the items off loaded individually.

 

Shelter kit layout - loaded on the truckHere is the riser blast hatch and the trusses on the flatbed truck.
