Urban and restricted-access sites
Ground screws (also known as screw pile foundations) are steel foundations that are mechanically screwed into the ground to support structures without the need for concrete. They provide a fast, strong, and environmentally friendly alternative to traditional concrete foundations in the UK.
Yes. Ground screws are ideal for domestic projects across the UK, including garden rooms, decking, sheds, extensions, pergolas, and annexes. They offer a clean and quick foundation solution with minimal disruption to your garden or property.
Ground screws themselves do not require planning permission. However, the structure being installed may require planning permission depending on size, height, and location. Always check with your local planning authority.
Yes. When designed and installed correctly, ground screws can comply with UK Building Regulations Structural calculations may be required for habitable or load-bearing residential buildings and may need approval from Building Control.
Yes. Ground screws perform particularly well in clay soil, which is common in the UK. Unlike concrete, they reduce issues related to ground heave and shrinkage caused by seasonal moisture changes.
Domestic ground screws are typically manufactured from hot-dip galvanised steel and are designed to last 50–100 years, depending on soil conditions and corrosion protection.
In many domestic projects, ground screws are cost-effective due to reduced labour, no excavation, no concrete, and faster installation. Overall project costs are often lower than traditional concrete foundations.
Ground Screws for Commercial Projects
Yes. Ground screws are widely used in commercial construction across the UK for modular buildings, offices, schools, retail units, solar farms, walkways, and infrastructure projects.
Ground screws are increasingly accepted by UK Building Control authorities when supported by engineering calculations, load testing, and manufacturer certification (UKCA or CE marking).
Yes. Commercial ground screw systems are engineered to support significant vertical and lateral loads. Load capacity is confirmed through torque-controlled installation and, where required, on-site testing.
Absolutely. Ground screws are ideal for temporary and modular structures as they can be installed quickly, removed easily, and reused with minimal environmental impact.
For most commercial installations, a ground investigation or torque testing is recommended to confirm soil conditions and load-bearing capacity in accordance with structural design requirements.
Ground screws are suitable for most UK soil conditions, including clay, sand, chalk, and loam. Specialist screws and coatings are available for challenging ground, made-up land, or coastal environments.
Ground screw depth typically ranges from 700mm to 2,500mm, depending on soil conditions, frost protection, and load requirements.
Most ground screw installations in the UK are completed within one day, often in just a few hours. Structures can be built immediately after installation as no curing time is required.
Yes. Ground screws can be installed year-round in UK weather conditions, including rain and frost, as long as the site is accessible and safe.
Yes. Ground screws are a sustainable foundation solution. They eliminate the need for concrete, reduce carbon emissions, minimise ground disturbance, and can be fully removed and recycled.
Yes. Ground screws are ideal for sloping sites as they can be installed at varying heights without excavation or ground levelling.
Yes. One of the major advantages of ground screw foundations is that they are fully removable and reusable, making them suitable for both permanent and temporary structures.
The cost of ground screw foundations depends on project size, soil conditions, access, and load requirements. While unit costs may be higher than concrete, overall installation costs are often lower due to speed and reduced labour.
Ground screws should always be installed by trained and certified ground screw installers using specialist machinery to ensure correct alignment, depth, and load performance.
Ground screws can be used for:
Ground screw foundations offer a fast, reliable, and eco-friendly alternative to concrete for both domestic and commercial projects.
Helical piles, also known as screw piles, are a modern, efficient, and environmentally friendly foundation solution used across the UK for domestic and commercial construction projects. Below are the most frequently asked questions about helical pile foundations in the UK.
Helical piles are steel foundation systems fitted with one or more helical plates that are rotated into the ground to form a stable load-bearing foundation. In the UK, helical piles are commonly used as an alternative to traditional concrete foundations for residential, commercial, and modular buildings.
Screw piles are another name for helical piles. In the UK construction industry, the terms helical piles and screw piles are used interchangeably to describe the same foundation system.
Yes. Helical piles perform well in most UK soil types, including clay, sand, chalk, silt, and mixed ground. They are particularly effective in clay soils, which are prone to shrinkage and heave that can affect concrete foundations.
Yes. Helical pile foundations can comply with UK Building Regulations when designed and installed correctly. Structural calculations, load testing, and manufacturer certification are often required for Building Control approval.
Yes. Screw pile foundations are increasingly accepted by Building Control authorities throughout the UK, especially when supported by engineering design calculations, installation records, and torque or load test data.
Helical piles themselves do not require planning permission. However, the structure they support may require planning approval depending on size, location, and intended use. Always consult your local planning authority.
Helical piles are typically installed between 1 metre and 3+ metres deep, depending on soil conditions, frost depth, and load requirements. Installation depth is confirmed through design calculations or torque controlled installation.
Yes. Helical pile foundations are engineered to support significant vertical and lateral loads. They are widely used in the UK for house extensions, commercial buildings, modular units, bridges, and solar panel installations.
High-quality helical piles are manufactured from galvanised or coated steel and are designed for a service life of 50 to 100 years, depending on soil conditions and corrosion protection.
Yes. Helical piles are a sustainable foundation solution. They eliminate the need for concrete, reduce carbon emissions, create minimal ground disturbance, and can be fully removed and reused.
Most screw pile installations in the UK are completed within one day, often in just a few hours. There is no curing time, allowing construction to begin immediately after installation.
Yes. Helical piles are commonly used in challenging ground conditions, including made-up ground, soft soils, and areas with a high water table. A ground investigation or load testing may be required to confirm suitability.
Yes. Screw piles are ideal for sloping sites and locations with limited access. They require minimal excavation and can be installed using compact machinery.
Yes. One of the main advantages of helical pile foundations is that they are fully removable and reusable, making them ideal for temporary structures or future redevelopment.
Helical piles are faster to install, cleaner, and more environmentally friendly than concrete foundations.
They allow immediate loading and often reduce overall construction time and costs in the UK.
Helical pile and screw pile foundations are used for:
For small domestic projects, a basic site assessment may be sufficient. For larger or commercial projects, a ground investigation, torque testing, or load testing is usually recommended.
Helical piles should always be installed by experienced and trained screw pile contractors using specialist equipment to ensure correct depth, alignment, and load capacity.
Helical piles offer a fast, reliable, and sustainable alternative to concrete foundations for domestic and commercial construction projects across the UK.
