The questions people actually ask.
97 direct answers across buying, installation, loads, ground conditions, durability, regulations, applications and UK coverage — with deeper owner pages where the answer depends on the project.
Choose the question closest to what you are trying to decide. Short answers come first; technical or commercial questions then link to the page that owns that subject.
Ground screw basics
What ground screws are, how they work and the terminology buyers come across.
Cost, prices & buying
What affects price, how to compare quotes and where supply-only or trade buying fits.
Size, quantity, loads & design
How screw quantity, depth, diameter, spacing and structural capacity are decided.
Ground & site conditions
Clay, rock, fill, slopes, wet ground, obstructions and other site conditions that can change the answer.
Installation & site process
How installation works, what access is needed, timing and what happens when a site is difficult.
Durability, corrosion & maintenance
Rust, galvanising, service life, removal and what to check about the actual product.
Building Regulations, engineering & approval
Building Control, calculations, planning and the evidence that may be needed on structural projects.
Applications
Where ground screws can fit and what changes between garden buildings, decks, extensions and larger structures.
Comparisons & alternatives
Concrete, pads, screw piles, anchors and when a different foundation makes more sense.
Quotes, installers & UK coverage
What to send, whether a site visit is needed and how local supply or installation enquiries work.
A direct answer first. Evidence and detail second.
Start with the exact question
Each answer opens with the practical response rather than making you read a long introduction first.
Follow the owner page
Cost questions lead to Cost, installation questions to Installation, load questions to Load Calculations and so on.
Do not copy a generic answer onto a structural job
Where the result depends on the building, ground or product, the answer says so and points to the information needed next.

Send the structure, dimensions, postcode, drawings and access information you have. We will answer from the project rather than inventing a generic number.
