What is a Screw pile?
In this Screw piles 101: All the basics you need to know blog, you will learn more about the advantages of screw piles. A screw pile is steel tube with a helical head that screws into the ground. it is used as a method of foundation in a wide range of constructions situations. Helix screw piles are suitable for making quick, easy and strong base for sheds, garden houses, log cabins,garages, fences, decks and many more.
A screw piles can offer a range of advantages over traditional concrete footings for example:
- Speed of install
- Install in limited access areas -Reduced man hour costs
- No waste removal
- Install in any weather condition

UK Helix specifically focus on smaller piles which are ideal for the DIY user and Commercial use on structures like garden houses, sheds, decking, fencing, noise reduction barriers, ground solar installs noise, reduction barriers and more. see our gallery here
What if you hit a hard rock with a screw pile?
This is one of the most common questions we are asked at UKHelix and we love answering it. There are a range of options in this case.
The first thing to consider is what type of ground are you going to use the screw pile in? Clay, Chalk or Peat for example?
Doing a soil survey is what we would recommend and is the first step to determining whether you are likely to hit rocks when using the screw pile and lets you know “what’s under the ground”
If you do hit a rock when using a screw pile there are still a good range of tactics you can employ.
For example, if you encounter a rock within the first 12 inches of drilling you can simply dig out the rock.
If you hit an obstruction whilst having already achieved sufficient depth to ensure the required load capacity of your structure. You can simply cut the pile using and angle grinder and re-drill the bracket whole.
How about when you hit an obstruction while having not achieved a sufficient depth? You can extract the pile and and re screw it further down the foundation line. Because of the strength of the pile and the flexibility of the bracket, you have rooms for adjustment.
Please remember that the first step to determining whether screw piles are a good solution for you is do a soil survey, even then if you do hit something hard there are a range of options at your disposal to ensure the screw pile installation is successful.

How do you build on a screw pile?
There are many ways to build on screw piles, from fixing wooden frames to brackets mounted to the screw pile to fixing a steel cage to the top of the pile and filling the cage with concrete. See 3 easy steps to install Helix screw piles
At UKhelix we specialise on smaller screw piles and provide a large range of brackets that allow you to fix any number of structures to the pile heads, from fence posts to decking from sheds to garden offices.
Typically though, once the screw piles are installed a wooden frame will be screwed to the piles using brackets for example “L” or “U” shaped brackets
Once the frame is in place you can start work on the structure immediately. This means that “potentially” you could have the screw piles installed in a morning and be building on the foundations within one day for a structure like a garden house, shed or log cabin.
