How can a dome be constructed to last? The temperature inside the insulated form stays within a comfortable range, and due to conditions of high relative humidity, the shotcrete regularly surpasses the required design strength of 4,000 psi. Call +1.208.522.5520 today or click here to request a free budgetary quote. The expected cost of the project was over budget. Occasionally clients want to purchase a dome strictly on price and think that because the domes proposed are the same geometry, have a similar outer membrane and are built with concrete, they must be the same. Domtec is a concrete dome construction company that doesn’t live on the edge of engineering theory. We have seen homes made from a variety of materials, some interesting and some so abstract as to question sanity of the builder. Commercial Applications. America's leader in earth sheltered construction for over 40 years! There is a 29-foot (8.8 m) salt-water swimming pool and a three-person hot tub in the living room of this incredible monolithic dome home. The dome's ability to withstand heavy products piled high against the walls minimizes the dome's diameter and the plant space it must occupy. Although we would not pass on a builder who we know to be a problem, this list does not constitute a recommendation or endorsement. Pricing. It’s difficult to design and build a dome that will last for 30 years, but not 31 years. It’s all about relationships. Rather than have employees on the payroll that would not be busy all the time, Domtec works with expert local engineers, consultants and contractors who know the project area and are adept in designing and constructing some portions of the project such as footings, tunnels and entryways. Product Links. (76 degrees when home and 79 degrees when not). At Domtec there is a saying, “In theory there is no difference between theory and practice, but in practice there is.” In other words, an engineer’s spreadsheet or computer model cannot take into account the tiny variations an inflatable air form will have once inflated, the slight differences in foam or shotcrete thickness, the minor variations in rebar distance or bar overlap or inconsistent shotcrete placement. Another engineer who had helped in the design of the Golden Gate Bridge in San Francisco proposed another ingenious design that cut the width of the truss by 67%, to only 8’. We are the original monolithic dome builders. SiloDomes™ are characturized by a dome on a cylinder, Stores large amount of product on compact footprint, More gravity reclaim than a hemispherical dome, Reclaim equipment typically less expensive than hemispherical dome holding same tonnage.

Case in point from another industry: In the 1930s an engineering study was commissioned for a 1.4-mile (2.25km) suspension bridge across the Tacoma (Washington, USA) Narrows. … Our monolithic dome building technology makes our structures energy efficient, strong, cost efficient, low maintenance and simply beautiful. Can double as a tornado or hurricane shelter, Large areas can be cut out to allow more daylighting and views, Can be built into conventional structures. Other companies spec 4,000 psi.
