Versatile micropiling system for use in homes suffering with subsidence, retaining walls, new build concrete-free foundations and infrastructure
Heli Pile was originally developed as a lightweight piling system for remedial works to housing affected by subsidence, but its versatility has opened it to be used in much more varied applications.
Used in combination with the Bar Flex masonry reinforcement system the Heli Pile can be designed and used as a standard “pile and beam” repair method. With handheld installation equipment, it can be installed in areas which are inaccessible to machinery.
For new build applications, foundations may also be cast onto the driven Heli Piles. Alternatively, custom end plates can create a completely concrete-free and recyclable foundation, ideal for a modern, environmentally friendly build.
Subsidence and heave are natural movements in the ground, typically exacerbated by the type of soil and varying moisture content.
Foundations are usually designed to withstand these movements, but can occasionally fail, leading to differential movement across the property.
Heli Pile can be used to prevent this differential movement by installing it outside of the property and pinning it back into the existing foundations using Bar Flex.
With a typical dig depth of less than half a metre, it is a far safer, cleaner and quicker solution than traditional underpinning.
For new build applications, such as a home extension or new conservatory, Heli Pile provides can be used as part of a block and beam or slab foundation, or as a completely custom concrete-free foundation.
By using Heli Pile, the amount of soil removed can be limited to less than half a metre – far less than traditional concrete foundations.
Heli Pile can be proof tested on site, in-situ, taking the guesswork out of piled foundations, and making over-engineering a thing of the past.
Heli Pile is manufactured from a part-recycled aluminium alloy, and can be fully recycled – making it the ideal solution for a temporary structure.
Heli Pile has been used in projects in conservation areas where extremely limited digging is permitted – and has been installed, removed and reinstalled to reduce costs when a semi-permanent structure is moved.
Heli Pile has been used to create concrete-free foundations in protected woodlands beacause it causes limited disruption during installation, limited damage to trees and limited effects to forests after removal.
Installed using handheld equipment, Heli Pile is perfect for areas with limited access. This is particularly an issue in cities and other built-up areas, where back gardens are completely inaccessible.
Heli Pile, and its installation equipment, can be walked through the middle of a home with very limited disruption, often providing the only realistic solution to extending a terraced home.
For structures in need of remedial work on the foundations that back closely onto other structures, Heli Pile can be installed in a very narrow gap – if you can fit a person in the gap, you can install a Heli Pile in it.
With the increasing need for masts in a communication world, Heli Pile can be the ideal partner for foundations.
Where 5G equipment is added to existing 4G masts, this may require additional load bearing on the existing foundations.
Heli Pile has been used in a wide range of new mast bases depending on requirements. Further, Target can create custom bases and works closely with large mast infrastructure manufacturers.
Heli Pile is a common solution for failed retaining walls, providing a hidden solution that saves having to remove and rebuild the affected wall.
By removing a few bricks, Heli Pile can be installed through the back of the wall to pin the soil behind and connect into the wall. The same bricks can then simply be replaced.
