Strong foundations.
Minimal ground disturbance.
Traditional foundations aren’t suitable for every project. Restricted access, difficult ground conditions, nearby trees and sensitive environments can make excavation and concrete foundations challenging.
Helical piling, also known as screw piling, offers an alternative. Steel screw piles are installed into the ground using specialist equipment, often requiring less excavation, spoil removal and concrete than conventional foundations.
360 GSS designs, supplies and installs bespoke helical pile foundations for residential, commercial and architectural projects across London and the Home Counties. From house extensions and garden rooms to balconies and waterside structures, our piling solutions are developed around site conditions, structural loads and project requirements, with structural engineering support available where required.

Restricted Access
Compact installation equipment allows screw piles to be installed on sites where conventional foundation methods may be difficult.
Less Disruption
Reduced excavation, spoil removal and concrete requirements can minimise disturbance to the surrounding site.
Verified Support
Helical piles can be load-tested where specified, helping confirm performance against project requirements.
Helical Piling Applications & Foundation Solutions
360 GSS provides helical pile foundations for projects where conventional excavation is difficult, disruptive or unsuitable.
Our screw piling solutions are suitable for a range of applications, subject to ground conditions and structural assessment:
We can also coordinate freestanding steel subframes and structural steel fabrication where piling forms part of a larger structural project.
Our screw piling solutions are suitable for a range of applications, subject to ground conditions and structural assessment:
- House extensions and renovations requiring engineered foundation support.
- Garden rooms and outbuildings on suitable ground.
- Balconies and terraces requiring stable structural foundations.
- Modular buildings and prefabricated structures.
- Waterside developments near rivers, lakes and canals.
- Restricted-access sites where larger equipment cannot operate.
- Projects near mature trees where excavation must be carefully managed.
- Elevated platforms and steel frames requiring dedicated foundations.
- Remedial foundation projects where specialist engineering identifies piling as suitable.
We can also coordinate freestanding steel subframes and structural steel fabrication where piling forms part of a larger structural project.
Our Helical Piling Installation Process
STEP 1
Request a Quote
Share your plans, drawings or project details so we can assess your foundation requirements.
STEP 2
Site Assessment
We review access, ground conditions, nearby structures and other site constraints, arranging further investigations where required.
STEP 3
DEPOSIT, Design & Engineering
Once the project is approved, a 50% deposit secures the work while the foundation design, calculations and installation details are finalised.
STEP 4
Pile Installation
Helical piles are installed using specialist equipment to the agreed design, with installation monitoring and testing where specified.
STEP 5
Testing & Handover
Required checks and testing are completed before the foundation system is handed over for the next stage of construction.
Helical Pile Foundations for Challenging Sites
Helical piling offers a practical foundation solution where traditional excavation and concrete foundations may be difficult to install.
Depending on the project, screw pile foundations can:
For projects involving balconies, terraces or elevated structures, we can integrate piling with bespoke steel support frames and balcony installations.
Depending on the project, screw pile foundations can:
- Reduce excavation and spoil removal.
- Minimise disruption to surrounding areas.
- Provide access to confined or difficult locations.
- Reduce concrete requirements.
- Support construction near sensitive landscapes.
- Allow installation in suitable waterside environments.
- Reduce waiting time associated with concrete curing.
- Provide engineered load-bearing support for bespoke structures.
For projects involving balconies, terraces or elevated structures, we can integrate piling with bespoke steel support frames and balcony installations.

What are helical pile foundations?
Helical piles, also known as screw piles, are steel foundation elements with helical plates that are rotated into the ground to provide structural support. They can offer an alternative to traditional concrete foundations for suitable projects.
What types of projects are suitable for helical piling?
Helical piling can be suitable for house extensions, garden rooms, balconies, terraces, modular buildings, waterside developments and restricted-access sites. Suitability depends on ground conditions, structural loads and project requirements.
Are helical piles better than concrete foundations?
Neither system is universally better. Helical piles can reduce excavation, spoil removal and concrete use, making them useful on constrained sites. Traditional concrete foundations may be more appropriate for other ground conditions and structures.
Can helical piles be installed near trees?
Potentially, yes. Their relatively low-disturbance installation can make them suitable near mature trees. However, work within a Root Protection Area requires appropriate assessment and may need arboricultural advice and local authority approval.
Can helical piles be used for waterside developments?
Yes, where site investigations and engineering confirm suitability. Helical piles may be considered for riverside structures, terraces and other waterside projects, with corrosion protection and environmental requirements assessed individually.
How is the load capacity of helical piles verified?
Pile capacity is established through engineering design and ground information. Installation monitoring and load testing may also be specified to confirm that the foundation system meets project requirements.
How long does helical piling installation take?
Installation times vary according to the number of piles, access, ground conditions and testing requirements. Some projects can be completed more quickly than conventional foundations because less excavation and concrete work may be required.
How much does helical piling cost?
Costs depend on pile dimensions, quantity, ground conditions, structural loads, access and engineering requirements. Contact 360 GSS with your plans or project details for a tailored quotation.
