Commercial builders now have a cost-effective solution for larger size projects based on technology proven successful in light commercial applications
(DALLAS—October 10, 2017) Tella Firma Foundations today announced a new heavy-duty commercial version lifting mechanism that is the cornerstone of its successful and patented elevated slab-on-grade foundation technology that has been used in more than 1,000 building sites in Texas and surrounding states.
The heavy-duty commercial lifting mechanism is designed for heavier commercial structures that are either large in size or have heavy load requirements such as concrete block interior or exterior walls. The heavy-duty lifting mechanism will allow the structural engineer to increase the spacing between piers because each lifting mechanism can carry a heavier load. The increased spacing will reduce the number of piers required for a typical commercial foundation design and make it more cost effective.
The Tella Firma foundation system is based on commercial engineering principles in practice for more than 50 years. The new mechanism can handle approximately double the load of the standard lifting mechanism. Tella Firma has conducted significant testing and analysis to ensure the new heavy-duty commercial lifting mechanism performs well in terms of both axial and lateral load capacity, wind load capacity, and life expectancy.
According to Jim Fontaine, CEO of Tella Firma, the company continues to innovate and collaborate with the commercial construction industry to develop new sustainable solutions for commercial projects based on their expressed needs. “Now commercial builders have a more cost effective means to take advantage of a solution that has been proven successful in the many foundation installations where our company has provided the technology,” he said.
The new product is currently being considered for several new commercial structures under design, including a school and a city municipal building. Many Independent School District (ISD) and other government buildings require either a crawl space or elevated slab solution, making this a primary market for the Tella Firma product.
Innovation through Technology
A Tella Firma lifting mechanism is an enabling component for the process of elevating a slab-on-grade foundation above the ground to create a protective void between the slab and the soil. This innovation isolates the foundation, helping to protect it from damaging soil swells, contractions and movements that may occur in many areas of Texas and the Southwest region, where active soils can cause foundation problems due to movement and settlement.
The Tella Firma lifting mechanism consists of a load-bearing imbed plate that sits atop a pile, a lifting bolt, which bears against the imbed plate, a threaded puck, cast in the bottom of the slab, which accepts the lifting bolt, and a sleeve and cap which prevent concrete slurry from fouling the puck threads during slab concrete placement. The new heavy duty mechanism works with either post-tension or rebar reinforced slabs, and includes a larger lifting puck and larger, heavier bolt to withstand the additional load.
The new heavy-grade commercial lifting mechanism increases the lateral load capacity of the foundation by two to three times. Analysis indicates the solution has a life expectancy of over 100 years under normal conditions.
