Steel Foundation is all about Strength
We use the best in the industry helical piers:
In average soil, driving a helical pier takes about 10-20 minutes, after which it is ready to build on. Readings from the installation are given to the inspector to show load rating. The pier and soil calculations are verified throughout the installation to carry the load, so no settling or movement will happen in the future. Helical piers will give you the peace of mind that you won’t have to return to a job site due to footings heaving or moving later.
A helical pier is a manufactured steel foundation pin that is driven into the soil to a depth below frostline using hydraulic machinery. Helical piers have been primarily used in heavy commercial work, but they are also well-suited for backyard decks, additions. Typical piers have a 7-foot shaft with a helical bearing plate welded to the end and a cap on top that attaches to the framing. All piers are load tested as installed so you as a contractor know exactly what it will support. The load-bearing capacity of a helical pier relates to the amount of torque required to install it, a function of both the size of the helix and the soil’s bearing capacity. A pressure gauge on the installation machine reads the torque as the pier is rotated into the ground.
In weaker soil, the pier will be driven deeper to reach stronger soil. When the helix is below frostline and the pressure gauge hits a high enough number relative to the loading requirements of the structure, the installation is complete. To calculate the actual bearing capacity of the pier, the pressure reading is plugged into a formula called a torque correlation. When poor soil conditions mandate going deeper than the standard-length shaft, an extension is added. Sometimes all it takes is a foot more depth to go from terrible soil to firm material. This is particularly relevant if building a freestanding deck where the piers close to the house might start out in backfill. If we were excavating to install a conventional concrete footing, we would have to dig down to virgin ground at the house foundation level — as much as 7 feet or 8 feet if the house had a basement. It is far easier to drive a helical pier to this depth.
Time is Money
When using piers, there is no waiting for the inspector, concrete dry time, etc. Pier installation causes minimal disruption to the customers yard/job site. There is no need to worry about the inspector arriving on schedule to look at footing holes — or about watching them fill up with water if he does not show. Once a pier is installed, you know exactly how much weight it can support and can start the building process. The load calculations are sent to the inspector while you move forward with the job.
SPtech Helical Piers utilize piers with Patented Cross Lock Connection, which can reduce installation time by up to 50%. The connection instantly aligns and locks in place, eliminating the need to line up bolt holes or wasting time threading a bolt through a deformed hole.
Cross Lock Advantages:
• Instant alignment
• Complete steel on steel connection
• Torque is fully contained in the coupling
• Zero bolt hole elongation during installation
• ICC-ER (ESR-3969) Certified

Steel Foundation is all about Strength
We use the best in the industry helical piers:
- 7 foot, 2-3/8" diameter leads made from the highest quality • galvanized steel
- Patented cross-bolt connection
- Higher torque capacity than the competition
- Patented 12" plate at the bottom of the pier provides superior lateral strength and stability
- Circular tapered plates (helices) are welded to the center of the shaft
- Helix pitch will range from 3"-6"
- Greater load capacity
- Installs in any season
- Not affected by high water table
- Minimal soil disturbance
