5 Things to Know about Helical Piers

If you are struggling with foundation problems, here are 5 things to know about helical piers to determine if the will help you. Not all foundation problems require foundation underpinning. Sometimes it can be a simple fix like a jack post install or sistering floor joists. Many times flooding and high humidity can be the cause of foundation problems no matter what the solution.

What is a Helical Pier & Underpinning

A helical pier and underpinning foundation repair system is a manufactured steel pin used in the building and correction of the foundation. The foundation underpinning can be used in commercial or residential projects. Helical piles can support everything from skyscrapers to bridges to homes to decks and walkways.

Many times helical piles are used to correct foundation problems in homes and other structures. Helical piers are considered a permanent foundation repair solution. Keep in mind there may need to be other solutions. Basement waterproofing, mold remediation, controlling humidity and even crawl space encapsulation may be needed along with helical piers, floor supports, carbon fiber bowed wall repair and sistering joists.

How Does a Helical Pier or Pile Work

When installing helical piers, the machine operator uses special equipment to twist the helical pile into the ground like a corkscrew. This is different than an auger removing the earth. The pier is permanently installed in ordered to support the structure. The pile is also specially designed to meet the load requirements of the project.

How Long do Helical Piers Last

Many factors determine the life of a helical pier. Some companies that use cheap materials in their helical piles will have a shorter life span. Crawl Space Ninja always uses the best products to ensure your home is protected and worry free. This is why we exclusively install Chance Helical Pile Foundation System. Based on the soil conditions, some manufacturers claim they can last up to 150 years. Chance helical piers offers a 30-year fully transferrable warranty. Many companies say they have a “lifetime” warranty but what is accepted legally as “lifetime” varies by state and sometimes can be as little as 7 years.

Are Helical Piers Expensive

Again this depends on many factors. Let's just say fixing your home's foundation is usually more than $1,000. Many home improvement referral companies say the average foundation repair using helical piers can be between $5,000 and $15,000. Remember, the size of the home, neglect of the repair and scope of the repair all plays a major factor in the cost of helical piles or any foundation repair project.

When Should I Use Helical Piers

Helical piers are used for compressive loads in relation to the foundation. This is typically when your footer, the part of the home that everything sits on, is damaged or shifted. Foundation underpinning will raise the footer and may theoretically raise the home but this may cause extreme damage to the interior and framing. The footer is typically compromised due to poor soil conditions and a pile is designed to add support where the soil has failed. The helical pile is installed to transfer the load through the poor surface soil, down deeper into good competent bearing soil in order to securely support your home's foundation.
