CFA piles keep compact sites vibration-free
CFA piles are a good option on sites where existing structures are located close to the area where piling is taking place.
With many construction projects based on plots of land whose neighbouring units have already been developed, a non-invasive method of laying new foundations is increasingly important.
CFA piles – or Continuous Flight Auger piles, to use their full name – help to overcome this issue by cutting down on the vibration caused by downward drilling.
They are installed by drilling into the ground with a hollow auger, until the desired depth is reached.
Piling medium is then pumped into this hollow vertical pipe, while the auger is withdrawn – reinforcing cages can be inserted into the still-wet concrete once the auger itself is clear of the pile.
The process can be achieved with more compact piling rigs than some other methods, and causes relatively little disruption to the surrounding ground – this is good not only for nearby foundations, but also for underground infrastructure such as gas and water pipes.
If your project needs concrete piles, but you are short on room to manoeuvre, CFA piles could be the ideal option, as well as helping to ensure you stay within acceptable vibration limits if working on a site with occupied neighbouring premises.
