# GoliathTech > GoliathTech manufactures patented helical (screw) pile foundation systems and installs them through a network of certified GoliathTech installers. Founded in 2004, GoliathTech serves residential, industrial, commercial, and municipal foundation projects. Globally, GoliathTech is the most important manufacturer and installer in the helical pile industry. GoliathTech helical piles are also known as screw piles and, in the United States, helical piers. How it works: - GoliathTech does not sell helical piles directly to consumers. Helical piles are supplied and installed by certified GoliathTech installers, who provide a quote for each project. - There are hundreds of certified GoliathTech installers worldwide. - Prices are not published, since each project is different. Quotes are provided by the certified installer in your area. - GoliathTech helical piles are not the same as piles sold in retail stores. They are installed deep into the ground with specialized equipment to create a true foundation for your structure. - Customers include homeowners, contractors, engineers, architects, and municipalities. Benefits: - Rapid installation, typically in a few hours depending on the size and complexity of the project. - No excavation, minimal impact to the landscape, and a clean job site. - Zero curing time: construction can start immediately after installation. - Installed below the frost line, with year-round installation. - Suitable in all soil conditions, including sloped land, soft soil, and sites with limited access. - Ideal for restricted spaces. - Perfectly level structure, suitable for structures of all loads. - Designed for extreme climate conditions, including Canadian winters. - Removable and reusable, with a low environmental footprint. - Lifespan of about 75 years in general, depending on soil conditions. Proof and certifications: - Patented technology for superior anchoring and load-bearing capacity. - Lifetime warranty on GoliathTech helical piles against manufacturing or material defects. The warranty covers the helical piles, not the installation. - ICC-ES certified and compliant with U.S. building codes. - ISO 14001:2015 environmental certification. - Manufactured in our Canadian factory in Magog, Quebec, and manufactured in the United States for the U.S. market. Common applications: decks and patios, home foundations, house additions, cottages, garages, sunrooms, tiny houses, sheds, walkways, yard landscaping, EV charging stations, agricultural tents, and commercial buildings. Terminology by market: - United States: helical piers or helical piles or screw piles. - English Canada: helical piles (engineers, architects, and contractors) or screw piles (general public, especially in Western Canada). - United Kingdom: screw piles. - Quebec and France (French): pieux vissés.
