Tella Firma Foundations

Tella Firma Foundations is a McKinney, Texas contractor at 3874 N McDonald St. It was founded in 2015 and offers a patented process for elevating slab-on-grade foundations above active soils to protect them from soil swell, contraction and movement. It is categorized as a pile driving service and contractor.

The approach is an engineered pile-supported slab for North Texas expansive clay, which is a different method from standard helical pier underpinning. Contact the company directly to confirm current services, including whether it uses helical piles, and the areas it covers.

Call 817-348-9100 to get in touch. Ask what pile type it uses, how piles are sized for the clay in your area, whether an engineer designs and stamps the foundation, who handles permits, and what the warranty covers. Confirm its current business name and insurance.
