What is the purpose of a helical pile?

What is the purpose of a helical pile?

What are helical piles used for? Helical piles are hollow steel tubes that are used to stabilize structures by anchoring the load to the surrounding ground, much like a driven pile. However, helical piles are screwed deeply into the earth, section by section if necessary.

What size helical pile do I need?

A residential repair for a foundation that has settled or is sinking would typically require a standard 2-7/8″ round shaft helical pile. A new deck installation, this type of project would also require a standard 2-7/8″ round shaft helical pile.

Are helical piles expensive?

When getting pricing from us you will notice that Helicals can cost around $30 dollars per foot. Meaning a Helical around 20-ft can be estimated around $600 dollars.

What are helical screw piles?

Helical piles, also known as helical piers or screw piles, are constructed using steel shafts with helical flights of various sizes to suit the site-specific ground conditions.

How are helical piles made?

Helical piles are created by welding a couple of steel thread threads on the shaft to present adequate downward pressure to the soil as it’s screwed to the ground. The helical piles plane is reasonable, although the form and dimensions may vary based on the program and type of project.

What is a helical in construction?

So, what exactly is a helical pier system and how is it used in both residential and commercial foundation construction and repair? A helical pier is a foundation pin made of steel that contains helices just like screws. It is driven into the soil, to depths below the frost line by use of a hydraulic system.

How much weight can a helical pile hold?

500 tons
Helical piles are capable of holding more than 500 tons of weight.

How deep do helical piles go?

between 10 to 25 feet
How deep can helical piers be installed? Most are installed between 10 to 25 feet below the soil but may be required to extend deeper if the required torque is not met. We have had some piles installed as deep as 100 feet.

How much weight can a Helical Pile hold?

How long do helical piles last?

As per the condition and load helical piers can last up to 120 years and even more.

What are helical piers?

Helical piers are shafts with helical plates that make them look like giant screws. This shape allows them to be screwed into the ground instead of pushed. They’re hydraulically rotated into the ground without applying any force to your foundation, and a pressure gauge system determines when the required depth is met.

What are helical supports?

The purpose of a helical pile is to provide foundational support for structures of all types and sizes. Just like old-fashioned pile-foundations, helical piles (also referred to as screw piles, helical piers, helical anchors, etc.)

What is a helix pile?

Helical Piles. Helical piles are a factory-manufactured steel foundation system consisting of a central shaft with one or more helix-shaped bearing plates and a bracket that allows attachment to a structure. The helix plates are commonly referred to as blades or flights and are welded to the lead section.

How to calculate the Helical steel in piles?

– Vertical Reinforcement = 20mm – 12nos – Outer Helical Ring = 8mm @ 200mm c/c – Inner spiral ties = 16mm @ 2000mm c/c

When and how to install helical anchors?

Helix Mooring Anchor self install. An eco friendly Helix conservation mooring used for a boat mooring or to hold your dock that you can install yourself. Simple self installation just turn it in with a pipe. – Impressive Holding Power. A Helix mooring anchor can get this holding power in a firm bottom. We can help you set this up using may different Helix mooring systems or change what you may already have in place.

What Are Helical Piers? Helical Piers are the anchoring systems used for building deep foundations and strengthening the foundation of the structure and made from tubular hollow sections. It is necessary to install helical piers if you want to protect the foundation of your structure.
