For certain small outdoor structures, large piling solutions aren’t necessary. A popular choice for some garden structures is to use screw piles; they are a cheaper alternative which provides more than enough support.
But what are screw piles?
Instead of driving a huge metal pile, screw piles work on the same principle of any household screw. Each screw pile is around 890mm long and winds into the ground using a simple portable hand drill. You may have seen similar technology being used on a much larger scale across construction sites – instead this time the hand drill would have been replaced with a crane that operates the screw pile.
The screws are placed at regular intervals in a similar fashion to other piles. The construction team then wind the screws into the ground. As they do this, the screws gain tension, creating a strong and sturdy foundation from which to build on. Each screw can hold around 7kN (kiloNewtons) of construction.
The Benefits
- Screw piles can be used on uneven ground without the need to dig. Digging requires much more machinery, which in turn will drastically increase the costs of the project as well as cause a huge disruption to your garden and your neighbours.
- Regular piling requires the pouring of large amounts of concrete, which is time consuming, as you will need to factor the drying time into your project timelines.
- Screw piles are much less intrusive and less damaging than most other methods of piling. So, if your project needs to pass through tree roots, the slimmer surface area of the screw pile will cause the least amount of damage.
- Screw piles are much more lightweight and accessible because they are implemented using nothing more than a hand drill. They can be installed where there is limited available space and access as they can be carried safely through a house or through a narrow side access with ease.
