Micro Pile Underpinning is a cost effect method to rectify subsidence movement in the soils under your footings. We permanent fix the structural integrity of your building. We service Sydney and regional NSW.
Helitec Structural Services are approved installers of Helifix systems including Dixie Micro Piles. Dixie Micro Piles is an efficient, economical and non-disruptive method of foundation stabilisation. Installing Micro Piles is the latest technology to permanently fix foundation movement and subsidence.
- Helifix DIXIE pipe piles provide structural support to a building’s foundations following subsidence, with minimum disruption to the occupants.
- Ideal for situations with restricted access.
- Screws into virtually any soil type.
Dixie micro piles are piles with a narrow diameter. They’re small, light and inexpensive, but can still carry a heavy load.
Sectional auger Micro Piles are bored with multiple flight sections added down to the desired depth. The concrete can be poured in either with the flights still in place or after extracting them, depending on the stability of the soil.
A chart of torque loads at different depths is completed during boring of dixie piles.
Your walls may be failing, and in a worst-case scenario, they may collapse.
- Minimal excavations are dug to the foot of the foundations at predetermined spacings.
- A notch is cut in the footings to enable the pile’s underpinning bracket to be located adjacent to the building wall to minimise the eccentric loading.
- The helical pile is ‘screwed’ deep into the stable subsoil using lightweight, hand-held equipment until the specified torque is achieved.
- This determines the pile’s load bearing capacity.
- Adjustable ‘L’ shaped brackets are fitted to the piles and placed under the foundations.
- The brackets are jacked up to mobilise the building load. Further subsidence is avoided with the building weight being supported by the piles.
