Type of Project
Techno Metal Post installs helical piers to support reinforced concrete beams for a 334 foot brick and block extension in Seasalter, UK.
Location
Seasalter, Kent, CT5 (United Kingdom)
Challenges
- 3 feet deep by 6 feet wide excavation requiring long-reach installation equipment
- Proximity to the sea (approximately 100 feet)
- Tidal water ingress within the excavation during works
- No load-bearing strata encountered up to 50 feet due to silt deposits
- Highly corrosive ground conditions due to tidal seawater exposure
Solutions
- Installation of 12 Techno Metal Post helical piers (model P3), installed to an average depth of 55 feet, achieving working loads between 85 kN and 130 kN
- Installation of Techno Metal Post's proprietary cathodic protection system, featuring two impressed current spin anodes, effectively preventing corrosion and ensuring continuous long-term protection
- Designed life-span exceeding 90 years, ensuring durable and reliable performance in a highly aggressive environment
Results / Conclusion
Despite challenging ground conditions, tidal water ingress, and adverse weather, all 12 helical piers were successfully installed within 5 days.
Techno Metal Post's helical pier foundation delivered a solid and high-performance solution, providing a stable and durable base ideally suited for the proposed single-story extension.
