Frequently Asked Questions
Find answers to common questions about ground screws and our services
Ground Screws
What are ground screws?
Ground screws are heavy-duty galvanised steel foundations that are drilled directly into the ground using specialist machinery. They provide immediate load-bearing capability and are a modern, eco-friendly alternative to traditional concrete foundations. Once installed, they create a stable base for structures to be built upon.
How long do ground screws last?
Ground screws are designed to last for decades. Made from galvanised steel, they are highly resistant to corrosion and can last 50 years or more in most soil conditions. The galvanisation process provides excellent protection against rust and environmental degradation.
What types of soil are ground screws suitable for?
Ground screws can be installed in almost all soil types, including clay, sand, chalk, and rocky ground. Our team assesses your specific site conditions before installation to ensure the correct screw type and installation method is used for optimal performance.
Do ground screws require planning permission?
In most cases, ground screw foundations for garden buildings fall under permitted development and do not require planning permission. However, this depends on the size and purpose of the structure. We recommend checking with your local planning authority for specific guidance on your project.
Can ground screws be removed?
Yes, one of the advantages of ground screws is that they are fully reversible. If needed, they can be unscrewed and removed, leaving minimal disturbance to the ground. This makes them an excellent choice for temporary structures or sites where future changes may be required.
Installation
How long does installation take?
Most ground screw installations are completed within a single day. The exact time depends on the number of screws required and site conditions. A typical garden room foundation with 6 to 12 ground screws can be installed in 2 to 4 hours.
What equipment is used for installation?
We use specialist handheld and tracked installation machinery designed specifically for ground screw installation. This equipment is compact and causes minimal disturbance to your property, making it suitable for sites with restricted access.
Can you install in difficult access areas?
Yes, our equipment is designed to access tight spaces and challenging areas. We regularly install ground screws in back gardens, narrow side passages, and other restricted access sites where traditional foundation methods would be impractical.
What happens if you hit rock or an obstruction?
If we encounter rock or an obstruction during installation, we have several options depending on the situation. This may include repositioning the screw, using a pilot hole, or adapting the foundation layout. Our experienced team will find the best solution for your site.
Cost & Quotes
How much do ground screws cost?
Costs vary depending on the project size, number of screws required, and site conditions. As a guide, a typical garden room foundation starts from around £800 to £1,500. We provide free, no-obligation quotes for all projects. Use our online calculator for an instant estimate.
How do I get a quote?
You can request a quote by contacting us via phone, email, or the contact form on our website. Provide details about your project including the structure type, approximate dimensions, and site conditions. We typically respond within 24 hours with an indicative price, followed by a detailed quote after site assessment if required.
Do you offer site assessments?
Yes, we offer free site assessments for projects within our service area. This allows us to accurately assess ground conditions, access, and any challenges, ensuring we provide an accurate quote and the right solution for your project.
Timber Bases
Do I need a timber base as well as ground screws?
While ground screws provide the foundation, a timber base creates the flat platform on which your building sits. Many garden buildings require a timber base. We offer a complete package including both ground screws and timber base installation for a seamless solution.
What timber do you use?
We use pressure-treated softwood timber that is resistant to rot, decay, and insect damage. The timber is graded for structural use and provides excellent durability for outdoor applications. All timber meets relevant British Standards for construction.
Can you match existing decking or structures?
Yes, we can work with you to ensure the timber base complements existing structures or decking. We offer flexibility in design and can adapt our approach to suit your specific requirements.
