We’ve been sharing our videos with the world for years and years, above is a very detailed overview 1hr+ video of every process to build a Quonset Hut Underground, we do not advise ever attempting without our guidance.

The videos below are for entertainment purposes only.

Then and Now - 12 years later! Zero water issues - zero moisture and same as it was when finished, which is quite rare for Undergrounds in the Pacific Northwest that rains constantly from November till May/June. This Quonset Hut Underground was built around 2011. In this video, we revisit the site for the first time since 2011 and share an in-depth tour of how it was built, reasoning for certain building techniques and address a few questions people have asked over the past few months. If you have any additional questions, leave a comment or send us an email! Thank you for viewing and click the Thumbs UP button if you enjoyed this video and found it informative! Email us @ VikingUndergrounds@gmail.com If you have any questions, desire blueprints to build your own, contact us directly over the email to talk on the phone.

***As a disclaimer, we do not advise, endorse, suggest, nor desire anyone to ever attempt this type of construction without proper engineering, supervision, certifications, and qualifications. All that we share is for entertainment purposes only. No individual should ever attempt this on their own without consultation. ***

Fifteen years ago David had friends building underground shelters, but he didn’t understand the attraction, until an ice storm took out his power and left him without electricity for a couple weeks. After building his own “concrete box” underground which doubled as both disaster bunker and guest house, he realized there was a faster and cheaper way to go underground. Instead of spending a year and $100,000 to place rebar and concrete forms, he began to bury Quonset huts for clients as a quick and more affordable solution to erect subterranean shelters. — Check David's Stealth Dome Home in the Pacific Northwest:    • Builds Quonset bunkers for a living. Lives...   After digging into a hillside or into the ground, the Quonset hut itself goes up in a couple days on top of a cement foundation (the corrugated metal structure was originally developed by the US Navy during WWII as a quick, lightweight housing that could be assembled with unskilled labor). Then a layer of spray foam is applied, followed by a layer of shotcrete (sprayed concrete). Instead of rebar, David uses Helix Steel or “micro rebar” to reinforce the concrete. Time can vary by the size and location of a project, but David estimates the entire process takes about a month. We visited the underground Quonset shelter (somewhere near Portland) that he built for a client in 2010. It has 3 bedrooms, a full bathroom, a kitchen with dishwasher and cast iron stove, plus a well with access from inside and a loft filled with several years worth of dry food.

Brief Photograph Overall View of The Construction Process For Our Quonset Hut Structures

  • Construction worker standing in a gravel lot, installing a light blue pipe inside a rectangular wooden frame, with various tools and construction materials scattered around.

    Gravel and Wooden Forms for Quonset Hut Slab

    An 8" layer of 1 inch gravel was dumped and then additional 6" of 1/2" gravel spread (along with drainage pipe)
    Preparing a level gravel base for black plastic and 4x4 forms for the 1ft Helix Steel Slab (No Rebar)

  • Construction site with black plastic sheeting covering the ground, wooden framework around the perimeter, and scattered construction tools and materials.

    Wooden Forms & Slab to Wall Concrete Cold Joint Seal

    2x4’s hold up Rubber Seal around the edge for Waterproof concrete cold joint to prevent any leaks
    (Half goes into slab, other half into walls)

  • Construction site with a partially built metal tunnel structure, workers present, and construction tools on the ground.

    Raising of the Quonset Hut Arches

    This is typically a 3 man job with scaffolding, a couple ropes.

  • View of the interior of a barn or similar wooden structure, showing unfinished wood framing, curved corrugated metal roofing, and sunlight filtering through gaps.

    4x4 Wood beams inside UG to reinforce structure for Shotcrete

    These are reused for building out the interior of the UG

  • Two workers wearing protective suits and masks spray foam insulation on a wall.

    Spray Foam Application

    This gives a proper surface for the concrete to stick to vertical surfaces & assists with waterproofing/moisture build up

  • A dam with water flowing over it, accompanied by a blue and white striped cloth or tarp on the left side, and some greenery at the bottom right corner.

    Continued Spray Foam

    Foam is sprayed to a thickness of 4 inches in the valley and 2” on the ridges.

  • Multiple orange buckets filled with steel wool and several cardboard boxes labeled HELIX stacked on a construction site with dirt ground and black drainage pipes in the background.

    Buckets of Helix Steel being prepared to pour into Concrete mixing trucks

    This will go into a shotcrete pump that pushes it into a 4” hose that is connected to a large air compressor that sprays small pieces of steel that has been mixed evenly onto the structure

  • Construction site with concrete wall reinforced with steel rebar and a flexible pipe at the bottom.

    The First Quonset Hut, we used two layers of rebar.

    Two 1ft x 1ft grid of #6 rebar with 6” on first layer, then another grid of rebar with additional 6” of shotcrete.

  • A man standing inside a building under construction with metal framing walls and an arched doorway.

    Inside view after 4x4 removed and interior door to the tunnel built

    Custom hand made wooden door that opens into the interior of Quonset Hut

  • Interior of a large metal safe door with multiple locking mechanisms and handles, open and showing the inside of the safe.

    Waterproof inside opening Marine Door

    You never want a door that opens to the outside incase debris is pushed against the front of it, if it does open, you need to have a hydraulic ram setup to push it open.

  • Construction site with two workers in orange safety jackets and helmets, large metallic structure, and equipment, with dust and dirt surrounding the area.

    Applying the Shotcrete with Helix Steel

    We decided to hire an outside shotcrete pumping company that traveled 100 miles to spray Helix Steel (no rebar) on this building.

  • A small, dome-shaped, earth-bermed structure with a metal door, surrounded by wildflowers and trees in a forested area.

    Front View of First Quonset Hut Built

    This is our First Quonset Hut Shelter built with rebar that is featured on our Youtube Channel currently.

  • Large concrete structure resembling a submarine partially buried in the ground at a construction site, with trees in the background.

    Side Outside view of first Quonset Hut

    A lot was learned on this project but even 13 years later, zero leaks or issues have been reported.

  • Close-up of a concrete utility box or cover on a construction site with dirt and gravel around it.

    Aerial view of completed Quonset Hut with No Rebar (only Helix Steel)

    As you can see, this Quonset Hut Shelter has skylights and a escape hatch (not visible here) on the backend. The air vent pipe is low in the front and high at the end of the building which creates a nature pull to circulate the air. (Options for complete shut down of air vents available)

  • Concrete tunnel opening under construction with dirt ground and construction tools inside.

    Entrance with sidewall view

    As you can see there is an air vent hole in the front, most customers don’t mind if that is visible but there are options to extend and make it go underground to a covert location.

  • Finished 40ftx32ft Quonset Hut with 20x8ft Tunnel

    This is the biggest one to date but it can be much larger.

  • Front Entrance with covered wooden patio area

    Customer wanted a covered patio area outside the entrance to the Quonset Hut Shelter (slab was poured after photo taken)

The image is blank with no visible objects or details.

    On Site Contracting

    Within the greater Pacific Northwest we are plenty capable of arranging a visit to your building site. However our preferred method is to work closely with a skilled contractor in your area.
    Once all materials are on-site, it takes approximately ONE month for the digging/grading, slab pour, Quonset hut erection, shotcrete entire building with Helix Steel, and final backfill.
    Depending on your caliber finished product you desire. The inside build out usually takes another month. The sourcing an costing out of big ticket items such as solar panels, generators, wells etc. come separately.

Building Quonset Hut Shelters since 2009~!!

We are a small operation based out of the Pacific Northwest that has built 10 or so Undergrounds in the past 20 years. None of the UG’s that have been built has ever leaked water even with receiving more rain then anywhere else in the USA. We took a break over the years but with how the world is, we figured, why not share this with people who might be interested. These are some of the nicest & strongest Undergrounds we’ve found over the years and nobody else can build them like us due to our experience which has given us more wisdom then money can buy!

We sincerely look forward to assisting you with your project! Free feel to ask us any questions!

Thank you & stay safe, we’ll leave the light on for you!!
