Secure Your Safety With ExSpar

Unlike most other builders who use parts made for other applications and retro fit them to a bunker, we design and make specialty parts specifically for bunkers.  You can't just go to your local hardware store and shop the emergency bunker section, so you are left with two choices; either find what's available and make it fit, but not function as it should, or design it to fit and function, then build it!  Thats exactly what we do.  From our hatches to our air pipes, we deigned them to work specifically with bunkers for functionality and safety. 

Our steel hatches are created will fail safe in mind.  We do not use gas shocks that tend to fail over time and exposure to heat.  We designed out hatches with internal hinge box and spring that won't fail you when you need it.  Our locks are both keyed and combination, non-electrical, all mechanical function.  If you forget to bring your key during an emergency, no worries, just punch in your code and you're in.  We have no lock loops where someone can lock you in your own bunker like other builders' hatches.  

Your bunker door is a vital part of your safety and security.  This is why we don't use marine style ship doors.  These doors are designed for ships, not bunkers.  They also open outward, not inward, which is a safety issue on its own.  Our doors are airtight.  Are they watertight? yes, but that's not the point or it's not our selling point like others.  These bunkers are not submarines and do not require watertight doors.  If your bunker floods to the point you need watertight doors, well, you have bigger problems to worry about because your air pipes are not watertight...

the escape tunnel is a great item to have in any bunker in the event your main entrance is compromised.  Why is ours better? Well, ours is safe, hidden, and reusable.  Don't fall for the gimmicky sand trap door, which are dangerous and cannot be closed once used.  Do you really want hundreds of pounds of contaminated sand filling into your bunker, only to have to punch through hundreds of pounds of dirt falling onto of you as you try to escape?  no, you don't.  These are dangerous sales gimmicks that look and sound cool, but by no means are they practical or safe.

These other builders only half finish their interiors to save time and money.  They just slap paint over the steel walls, which will sweat during use, and they are cold to the touch.  With the amount of money you are spending on a bunker, you shouldn't have painted steel walls.

All of our square steel bunkers have actual finished interiors to include the walls all around.  They are insulated between the steel and the interior wall to help control temperatures and feel like a home.  This is not an upgrade, these interiors are standard in our bunkers.
