New Foundation System Appears to Levitate Above Harmful Expansive Soils
(Colorado Springs, CO—(ReleaseWire)— January 7, 2016) A groundbreaking new building foundation system is being introduced to Colorado. This innovative system provides solutions for expansive soil problems that are prevalent throughout our State.
RMG – Rocky Mountain Group, a Colorado Springs based architectural and engineering company, is the pioneer of the technique that is gaining fast recognition throughout the Front Range as a viable solution to a century’s old problem. RMG is excited to announce that the Tella Firma™ Foundations system is becoming the answer to most expansive soils problems. “Builders are constantly asking us for better ways to address our expansive soils problems,” says John Clarke, President and Owner of RMG-Rocky Mountain Group.
A new home is now being constructed by Vanguard Homes on this advanced new technique. The home will utilize the Tella Firma™ system in the basement and garage. This unconventional system, designed by RMG-Rocky Mountain Group, lifts the foundation supporting the house off the ground from a grid of deep foundation piers, creating a more stable structure.
Expansive soil is defined as soil containing clay that swells when it is wet and often shrinks when it dries, creating havoc for many buildings foundations. When RMG conducts a soils test on a future home site, they may determine that the soil has certain expansive characteristics that could affect a traditional foundation system. The most common solution in the El Paso County area, is to recommend an over-excavation scheme which involves the removal of three feet or more of the expansive soil and replacement with non-expansive soil. “The conventional approach of overdigging these sites is getting more expensive every year,” says Clarke. However, to avoid this costly over excavation option and promote a more stable foundation for the new home, Vanguard Homes has chosen to incorporate this innovative foundation design known as Tella Firma™. This patented system greatly reduces the potential for foundation and slab movement caused by expansive soil by literally suspending the foundation platform above the troublesome soils.
The patented process works by installing a grid of deep piers designed for the anticipated expansion in the soil. A structural concrete slab floor is poured on top of the ground and then raised six or more inches above the soils with the use of specially engineered lifting mechanisms supported on the piers; this creates the desired gap from the harmful effects of the expansive soil.
Constructing a structural floor above expansive clay soil has typically been considered the best approach to maintain a stable floor. Most structural floors require crawlspaces that are difficult to ventilate and involve deeper excavations and taller foundation walls. Using a concrete structural floor eliminates these requirements. But in the past, it had been costly to construct concrete structural floors which require elaborate form systems that were necessary to support the floor above the ground. This process was limited to more expensive homes and commercial buildings. Tella Firma™ Foundations system offers a unique and patented approach by lifting the concrete foundation without the use of the form system (as described above) at a more affordable cost, significantly reducing the required material, labor and construction time.
Tella Firma™ Foundations system also utilizes a post-tensioning structural concrete floor that is based upon existing engineering principals that have been in use for many years in commercial buildings and parking garages. Adapting a similar fundamental approach, RMG – Rocky Mountain Group, has designed a stronger structural concrete floor that requires fewer support piers, further lowering the cost.
This current project is a residential home that will utilize the Tella Firma™ Foundations system for the basement and also the garage. While Tella Firma™ is not the only foundation system for a new home; it is the most cost effective in terms of protection from our volatile soils. “This system has already been used on the highly expansive soils in Texas in over 1000 homes,” adds Clarke.
Colorado Foundation Solutions (CFS) is the only supplier of the Tella Firma™ lifting mechanisms in Colorado. CFS also provides cost estimates to compare Tella Firma™ to traditional systems and training of, or references for, installation contractors. RMG, or your engineer, designs these foundations through our elaborate finite element analysis software systems.
CFS and RMG will be demonstrating the revolutionary process at the Vanguard Homes building site in a local Colorado Springs subdivision. RMG will be providing tours of the home site to all interested parties. Engineers, Architects, residential and commercial Builders, General Contractors, Land Developers and future home buyers are encouraged to tour the site and observe engineering innovation take place.
