Why Not Pipe or Culvert:

Using round pipe or culvert as a bunker has many downfalls. Space utilization is greatly diminished due to the fact that the floor has to be raised off of the bottom to accommodate enough flooring to walk on. The only place you actually get the full height of the bunker is dead center of the walkway. The walls are rounded so you are losing almost half of the space you would have using a squared design. Another downfall is that everything built to go inside the bunker must be rounded since noting can fit flush against the rounded walls. The galvanization is removed when the metal is welded on, which in return causes rusting to be accelerated and degradation of the overall integrity of the structure.

Why Concrete Shelters Are a Terrible Idea

Concrete gained popularity as a widely accepted material for storm shelters in the World War II era. However, as time went on, it was apparent that there was not much longevity for them. They leak, mold, crack, settle, and loose integrity over time. Concrete is even more vulnerable with the humidity and soil conditions. Soil expands and contracts greatly as its heated and cooled, leading to cracks in the structure. Cracks must be maintained on a regular basis which is expensive and time consuming. If left untreated, they will compromise the integrity of the shelter. After cracks develop, they begin to hold moisture and mold and are prone to collapse. Think about it, this is why you will not find a concrete shelter with a warranty longer than 10 years. Look around and you will see that the leading concrete storm shelter company that offers the “best warranty in the business” with its “lifetime limited warranty” only last 10 years. It does not cover cracks caused by the expansion and contraction, water leakage, seepage, or much else. It only covers manufacture defects. Concrete shelters are outdated, dangerous and very expensive over time.

If not maintained regularly, concrete storm shelters quickly deteriorate and become more of a safety issue. A storm shelter should not be a safety hazard and maintenance issue, it should be in place to protect your family! The only reason they still build them is because they are cheap to make, and they can make a lot in very little time (maximizing profits).

Why Fiberglass Is Not All That It's Cracked Up To Be

Fiberglass storm shelters have a great weakness. Fiberglass is prone to deterioration by UV rays and moisture. It has the same problems with mold and mildew if left untreated. The mold and mildew itself will also deteriorate fiberglass. Fiberglass has a significantly greater maintenance cost. Most fiberglass shelters are not all the way underground, and the UV rays cast from the sun do damage to the part that sits above the ground causing microscopic cracks. Those cracks could cause it to shatter!

Fiberglass shelters are cheaper to produce; they form the shelter by using a mold and are able to mass produce them. Yet they are MORE expensive! They are generally tiny and you will pay way more per square foot yet not get the same protection or durability.

Think about it, cars and toys from the 50’s where constructed of steel, now most cars have a fiberglass body and most toys are made of plastic. Which ones last longer? Fiberglass shelters are good for one thing, MAXIMIZING profits for the builders.
