Common questions about screw pile foundations, installation and costs across Essex.
Everything You Need to Know
Screw piles, also known as helical piles or anchor piles, are steel foundation piles with helical flights that are screwed into the ground. They offer a faster, cleaner and vibration-free alternative to conventional driven or augered piles.
It really depends on your project — the structure, pile size, and soil type all affect the cost. Please share your drawings with us and we'll provide an estimate.
Yes, since there's no requirement for concrete, screw piles can be installed in any weather conditions, unlike some conventional foundation methods.
Screw piles are quick to install compared to conventional piling methods, with load able to be applied immediately after installation. Exact timescales depend on the number of piles and site conditions.
Yes, screw piles are commonly used to underpin and stabilise properties affected by subsidence, installed in line with UK Building Regulations, with piling logs handed over for Building Control.
Yes, screw piles are engineered to anchor into a range of soil conditions, including challenging clay soils, providing stable load support where the ground would otherwise complicate conventional foundations.
Yes, screw piles can be removed when no longer needed, making them well suited to temporary structures or projects where future relocation is a possibility.
Screw piles suit projects of almost any size, from a garden room or decking through to extensions, new builds and larger commercial developments.
A foundation drawing with the point loads is ideal. If you're not sure what's needed, send over whatever drawings you have and we'll check them for you.
