Building EcoShells Without Steel?

Why are we building EcoShells without steel? 

Steel reinforced concrete is an incredible invention that has allowed for the construction of all the major cities that exist today.  However, if water is allowed to reach the steel embedded in the concrete it corrodes the steel, causing it to expand and crack the concrete.  Most of the bridges in the US and around the world are suffering from this flaw that in some cases causes failure of the structure. 

We have started working with Basalt rebar on our EcoShell projects and have developed specific basalt products to help with the construction of EcoShells.

We are the first company to build viable EcoShells with absolutely no structural steel elements.  Using basalt to provide the tensile strength component in our concrete, we can build EcoShells that are structurally sound and will be unaffected by the possibility of steel corrosion. This allows less concrete to be used and the lifespan of the buildings to be greatly increased.

Why Domes?

Why Domes? 

We are all becoming more and more aware of how vulnerable we are to extreme weather events - fires, hurricanes, tornadoes, floods as well as earthquakes and drought.  There was more sad news this week as lives were lost and awful damage was caused by tornadoes in the southern United States. ( 

We need to be prepared and protect ourselves from future events.  Monolithic Domes and their developing world counterpart - EcoShells are the answer in many cases. We have to realize that the old way of construction is not serving us any more and look to the future.

A Monolithic Dome was the only building left standing after a devastating tornado in Moore, Oklahoma in 2013.

"Near-Absolute Protection" - FEMA

One of the most unique and desirable features of a Monolithic Dome is its durability in the face of manmade and natural disasters. Monolithic Domes been labeled by FEMA (Federal Emergency Management Agency) as providing "Near-Absolute Protection." 


This stunning home in Pensacola Beach, Florida (one of the first google-image results you'll find for "Monolithic Dome" because of it's beautiful design) has survived hurricanes Ivan, Dennis and Katrina.


In 2013 an EF-5 Tornado devastated a large area of Moore, Oklahoma. This Dome was the only structure left standing. 


A concrete dome in Omak, Washington survived a wildfire in 2015, undamaged. Its owner remained safely inside the home during the fire. 


At the end of the day, our company's mission is to make the world a safer place to live in. 

Roman Roman Concrete Endures in Spain!

The Romans used 'opus caementicium' or conrete as we know it to build the core of their buildings like this amphitheater. They used lime pebbles and river sand as well as medium sized amphibolites (a kind of rock) as the aggregate.

The well preserved amphitheater and theater exists today in Merida, Spain - an ancient Roman town built for retired soldiers.

Hurricane Matthew

Haiti has once again suffered yet another natural disaster. Obviously our thoughts are with all the people affected by the Hurricane Matthew. News of the hurricane brings back memories of the time I spent in Maniche, just inland from Les Cays on the Southwest part of Haiti. I was there three years ago to construct a forty foot diameter EcoShell for the Haiti H.E.R.O. organization. I don't have any news yet about the area although I know the EcoShell will still be standing. 

Our changing global climate has increased the number and severity of natural disasters like these. Our passion at is to provide as many people and communities as possible with safe and disaster-resistant shelter.  If we can be of service please contact us. 

As news becomes available I will post some updates.

Concrete Through The Ages

Dan Hildebrand, founder of HDomes Consultation & Construction recently visited the town of Mérida in Spain.  The town was founded in 25 BC, with the name of Emerita Augusta (meaning the veterans – discharged soldiers – of the army of Augustus, who founded the city; the name Mérida is an evolution of this) by order of Emperor Augustus, to protect a pass and a bridge over the Guadiana river  Mérida is probably the best preserved of all the Roman towns in Spain and use of concrete as one of the main building components is still visible everywhere.  An amphitheater - where gladiators fought, a theater - where plays were performed and the Circus Maximus - where chariot races were held, and a huge viaduct that supplied the town with water are all still visible.
