TTT Under House Piling

With TTT Under House Piling you easily can repair your foundations without the hassle of moving your home off-site.
How it’s done

TTT Under House Piling uses TTT MultiPole UniLog piles that are 1–2.4m long. These are small enough to easily manoeuvre under your house, and can be joined together to reach required depths.

We’ll raise your house to achieve a minimum of 2.4m ground clearance. We’ll then vibrate UniLog piles into the ground using specialised, compact piling equipment. This installation process leaves pile tops undamaged, and has minimal effect on neighbouring properties.

Benefits of this system

•  Typical installation time of 5 days.

•  Installation uses non-damaging high frequency vibration.

•  No need to move your home off-site.

•  Our small, specialised piling equipment works efficiently in small spaces.

•  Uses award-winning TTT MultiPoles.

•  PS1, PS3 and PS4 provided.

Additional design options

Because TTT MultiPoles have hollow cores, reinforcing rods can be grouted through them for added strength following installation.

Installing Deep Pile Foundations under your existing home is no problem. Our TTT MultiPole Connectors allow us to join piles during installation until a competent bearing layer is reached. Find out more about our Deep Pile Foundations or view the case study below.

Geotechnical report

Site-specific design

Site visit and installation

First of all, we’ll need a geotechnical report for your site. If you don’t have one of these, we’ll help you get one.

This will be based on your geotechnical report, and could involve the customisation of one or more of our existing foundation systems.

Our installation processes are fast and efficient. They’ll have minimal impact on neighbouring properties and will leave your site undamaged.
