Frequently Asked Questions

What are some the advantages of using piers for carports?

Piers are superior to other methods in many ways. Hand-dug and drilled concrete piers can do an adequate job. However, they are extremely time-consuming, messy, expensive, and labor-intensive. Concrete piers are also susceptible to weather-related problems such as frost heave and water damage. Driven Piles can be effective, but limited access and sensitivity of existing buildings make their use difficult for an installer. Helical piering is cost-effective, requires little to no concrete, can be performed in limited access situations, and is virtually vibration free.

What is the life expectancy of piers when used for carport applications?

Many factors determine the life expectancy. Though Helical Piers can be galvanized to prevent rusting, the varying soil conditions can affect life expectancy. It is the general estimation that piers last over 150 years in normal soil conditions.

What kind of warranty or guarantee do you offer with your helical piles?

We offer a 75-year limited warranty.

What kind of equipment is used for installing piers for carports?

PierTech™ offers installation equipment that attaches to skid steers, mini and full-size excavators, and backhoes. PierTech™ even offers handheld installation equipment for limited access areas. The stages of helical pier installation include soil analysis, precise torque application, and professional oversight to ensure stability and compliance with local building codes.

How many helical piers are needed?

The number of helical piers needed depends on the size and weight of the structure, the building components being supported, and the condition of the soil. Factors such as the length, size, and additional needs like concrete, brackets, or beam caps can also affect the cost.
