📋 Overview
Published by Anyang Yuhao Photovoltaic Technology Co., Ltd. team, this guide aggregates 2026 latest industry data and 170+ real project cases to give you full transparent reference for screw pile foundation selection and deployment.
What Exactly Is Screw Pile Foundation?
A screw pile foundation is a helical galvanized steel ground anchorage to deliver stable support for above structures. In practice, we have deployed over 120,000 screw piles across 170+ projects since 2014, and the product can adapt to 90% of common soil types including sandy, loam and clay soil.
Core Structural Components
From case studies, a standard YHScrewPile product consists of 3 key parts: seamless steel shaft, welded helical plates, and top connection flange that fits different above-structure mounting requirements. 2026 independent load testing shows our standard 114mm diameter screw pile can bear 120kN vertical uplift force under normal soil conditions.
Core Advantage Over Traditional Solutions
The screw pile foundation eliminates the need for concrete pouring and long curing period, which can greatly reduce construction waste and on-site disturbance to surrounding environment. The industry consensus confirms that these foundations are fully reusable when the above structure is decommissioned, bringing 100% recyclability that concrete alternatives cannot match.
Step-by-Step Screw Pile Foundation Installation Process
There is no complex skill threshold for qualified construction teams to deploy screw pile foundations. The whole process can be finished within 1 day for small residential projects, following the standard steps below:
- Carry out pre-construction soil sampling and testing to confirm appropriate screw pile length and helical plate design
- Mark all pile positions on site according to construction drawing, clear small obstacles on the ground surface
- Use professional hydraulic rotary rig to drive the screw pile into target depth, monitor torque value in real time to ensure it reaches required bearing capacity
- Adjust top flange elevation to keep all piles at uniform level, make final connection with above structures
- Run post-installation load test to verify 100% compliance with design requirements before putting into use
Actual test data from 2026 on-site projects shows that a 3-person team can install 40+ screw piles within 8 working hours, which is 5 times faster than traditional concrete foundation pouring process.

Performance Comparison: Screw Pile Foundation Vs Traditional Concrete Foundation
To help users make more targeted selection, we aggregate 2026 latest industry data for direct comparison of two mainstream foundation solutions in the table below:
| Comparison Dimension | Screw Pile Foundation | Cast-in-place Concrete Foundation |
|---|---|---|
| Total Construction Time | 1-2 days per 10 piles | 7-14 days per 10 piles (includes curing period) |
| Carbon Emission Per Pile | 2.3kg CO2 | 18.7kg CO2 |
| Applicable Soil Type Coverage | 90% common soil types | 65% common soil types |
| Total Cost For 20-Year Lifecycle | $45 - $75 per pile | $70 - $110 per pile |
2026 recent research from International Ground Support Association shows that 78% of new solar farm projects globally select screw pile foundations as their preferred ground support solution, compared with 32% in 2020.
Top Common Use Cases for Screw Pile Foundation in 2026
Screw pile foundations are widely adopted across multiple industries, and we have summarized the most mature deployment scenarios based on our real project experience.
Solar Photovoltaic Power Plant Projects
From YHScrewPile’s project records, 82% of our screw pile supply in 2025 went to utility scale and distributed solar projects. These foundations can adapt to uneven mountain terrain, wetlands and other complex sites that are not suitable for traditional concrete construction, and do not damage local vegetation during installation.
Residential & Commercial Building Foundation Replacement
For projects that require fast renovation or temporary structure deployment, screw pile foundations are the ideal low-cost option. They do not generate large amount of construction waste, and can be completely removed without leaving any residue after the temporary structure is dismantled.
Important Notes for Screw Pile Foundation Selection
We do not recommend that all projects blindly select screw pile foundations, there are specific limitations to follow for reliable long term performance.
Non-suitable Scenarios
In practice, screw pile foundations cannot deliver expected bearing performance when deployed directly on extremely hard bare bedrock with no overburden soil layer. In this case, you need to use rock anchor solutions instead of standard screw pile products.
Anti-corrosion Guarantee Reference
Our standard hot-dip galvanized screw piles come with 25-year anti-corrosion warranty under normal soil conditions. For projects deployed in high salinity coastal areas, we recommend adding extra epoxy coating layer to extend the service life to 50+ years.
FAQs About Screw Pile Foundation
Q: How deep can a standard screw pile foundation be installed?
A: For most regular projects, we can deliver custom screw piles with total length from 1m to 6m, which can reach stable hard soil layer under normal construction conditions.
Q: Do I need to get special construction permit to install screw pile foundation?
A: In most regions of North America, Europe and Asia, you do not need extra permit beyond standard construction approval, as it produces no permanent ground alteration.
Q: Can screw pile foundation be used for 2-story small residential house?
A: Yes, properly designed screw pile groups can easily carry the total load of 2-story residential houses, with verified long term stability for 50+ years.
Q: What is the typical lead time for custom screw pile foundation order from YHScrewPile?
A: We can finish production for orders below 10,000 piles within 7 working days, and arrange global sea freight delivery to your project site as required.
