FAQ

Q: How much weight can a screw pile support?

Q: What is the recommended distance between screw piles?

Q: What happens if we encounter a rock in the soil?

If a rock is encountered, GoliathTech Manchester will determine the most suitable approach, which may include:

  • Slightly shifting or relocating the pile, if feasible and permitted
  • Using heavier, specially adapted equipment to minimise disruption
  • Exploring alternative solutions in consultation with a structural engineer

Our goal is always to maintain safety, efficiency, and compliance with project requirements.

Q: Can helical piles be installed under an existing structure?

Yes. As long as there is access near the structure—such as by temporarily removing a few blocks or boards—GoliathTech Manchester can install piles even in hard-to-reach areas using handheld devices or compact equipment.

Q: Can I install helical piles myself?

No. Installation requires certified professionals and specialised equipment to ensure safety and performance. GoliathTech Manchester is an approved installer of GoliathTech and provides expert installation solutions.

Q: Can helical piles be installed through asphalt for a carport?

Yes absolutely it can be done without any issue.
GoliathTech Manchester uses compact equipment to drill through asphalt, and the surface can be repaired afterwards.

Q: How do helical screw piles compare to concrete post foundations?

Helical screw piles offer rapid installation, require no curing time, and provide long-term cost efficiency. They reach the optimal soil depth, deliver superior anchoring, and comply with stringent industry standards. Additionally, their minimal excavation supports sustainable construction by reducing CO₂ emissions.

For example, a 60R helical screw pile was installed in just 5 minutes and 1 second. By the sixth minute, the pile head was fitted, and by the seventh minute, it was ready for loading. On a project requiring 12 piles, the entire installation was completed in just half a day.

Q: Are any checks required before installation?

Yes. Utility locations such as water, gas, electrical, and sewer lines must be verified before installation.

Q: Do your helical piles come with a warranty?

Yes. GoliathTech Manchester provides a warranty against manufacturing defects, backed by GoliathTech Corporate Canada. For full details, please visit:

Q: Can piles be installed on sloped terrain?

Yes, easily. GoliathTech Manchester assesses site conditions in advance and, if needed, uses specialised equipment to ensure efficient and safe installation.

Q: What is the life expectancy of a screw pile?

Typically over 75 years under normal conditions (minimum 50 years by code), depending on soil pH and moisture levels.

Q: How many piles will my project need?

This depends on several factors, including the size of the structure, construction type, load requirements, and soil conditions. GoliathTech Manchester’s engineering team will carry out a detailed assessment and, in most cases, provide a full design to ensure optimal performance and compliance.

Q: Can helical piles be reused?

Yes. They can be removed and reused (conditions apply), supporting sustainable construction practices.

Q: How deep can helical piles go?

Up to 20 metres or more or less, depending on soil conditions.

Q: How are helical piles installed?

Helical piles are installed using a mini excavator that rotates the pile into the ground like a screw. Installation torque is measured to verify load capacity, while the minimal excavation process helps reduce environmental impact.

Q: What if the site is restricted or hard to access?

GoliathTech Manchester can use compact, specialised equipment designed for tight spaces.

Q: What if there is a high water table?

GoliathTech Manchester carefully evaluates soil conditions, and our engineering team designs each system accordingly to ensure long-term stability and performance.

Q: How is torque measured during installation?

Using a hydraulic gauge or electronic torque-measuring tools connected to the hydraulic motor for precise readings.

Q: When can I start building on helical piles?

Immediately after installation—no curing time needed.

Q: Do you offer engineering services?

Yes. Share your plans with GoliathTech Manchester, and our engineering team will handle the rest.

Q: What are the advantages of helical piles over concrete foundations?

Faster installation, no curing time, cost efficiency, optimal soil depth, superior anchoring, and compliance with top industry standards. Helical piles also support sustainable construction with minimal excavation and reduced carbon footprint.
