FAQs
Ground screws are a revolutionary foundation for structures that can be used for many different types of projects, both commercial and residential. As one of the leading companies in the UK with the facilities to install ground screws, we are your first choice to get your project completed. You can read our FAQs below, but should you have any other questions, please do not hesitate to get in touch.
Ground screws substitute traditional foundations and eradicate the need to lay concrete.
Uninterrupted threads on a tapering body allow the Ground Screw to thread itself into the ground, compressing the surrounding area, offering incredible loadbearing.
We are able to carry out load testing on-site to validate capabilities and strength for engineers and building inspectors.
Ground screws enable you to start your building project quickly, with minimal mess and damage, no matter what the season.
Yes, all of our ground screws can be supplied and fitted in any weather, even snow! This is because of 2 things:
- The strength of the screws; our screws are able to withstand significant forces without compromising on their integrity, this is especially important when screwing into frozen ground.
- Equipment used: our specialist electric hand turning machines mean we’re able to install and extract screws from 76mm to 114mm in diameter using up to 4700Nm of torque.
Screw piles are unique among most other types of piling in that they can be loaded immediately after installation. There is no need to wait for concrete or grout to harden. In most soil conditions, the ultimate capacity of screw will increase slightly with time, this is particularly true with cohesive soils. We can also come to site a complete a ground test to determine what size screw you require for your needs.

Ground Screws are much quicker to install and feature a wide range of advantages over concrete. When comparing the Ground Screws’ raw material cost against concrete, it is more expensive, but offers long term quality benefits like no frost heave, no post rot and the potential to be removed with ease and re-used. Compared to Helical Piles, the biggest advantage is staying within budget. It is a fact that Ground Screw foundations do not have to be installed as deep as Helical Piles because there is much more soil displacement and compaction occurring during installation. Therefore in many cases, a Ground Screw can reach its required ground resistance significantly faster than a Helical Pile.
Ground screws can generally work around smaller tree roots with little issue. However, larger roots may be refused.
We have overcome challenging situations where there has been restricted access or where the ground was uneven and thought to be completely unusable. Thankfully, our ground screw foundations system means there is no need for heavy machinery, skip hire or extensive ground clearance. Ground screws can be installed on uneven or sloping ground to provide a solid flat base for your holiday lodge or glamping pod. You can reduce the cost of foundations by up to five times that of a traditional concrete pad.
