Subsidence becoming an issue?
Our helical screw pile underpinning system provides a reliable, cost-effective solution for treating subsidence in residential and commercial buildings across the South of England. Designed to stabilise foundations and prevent further structural movement, this advanced piling method offers minimal disruption and long-lasting results.

If you're experiencing signs of subsidence such as cracks in walls or uneven floors, our expert team at Alternative Piling Solutions, based in Wiltshire is here to help. We specialise in underpinning and foundation repair, delivering tailored solutions to suit your property.
Underpinning & Subsidence.
The advantages are many; this is a fast system to install, is minimally invasive and prevents any further subsidence from occurring.
Our handheld installation option allows for installation in small spaces or sites with limited access. There is little noise or ground disturbance and it can be installed into most ground types.
Screw piles are extremely shrub and tree friendly as the slender shaft causes virtually no damage to the root systems and are therefore highly recommended by arboriculturists. We offer different sized piles to suit your required loadings.
Advantages.
The Process.
Where required we will work to the structural engineer’s design and calculations to remedy your subsidence. This, if necessary, will determine the pile size, quantity and the loading per pile which ensures that the structure is correctly supported. The pile positions are marked out and trenches are dug accordingly to expose the bottom of the existing foundations.
Peace Of Mind.
Each helical screw pile is then installed with a digger mounted or hand-held torque head. During installation a gauge constantly measures and monitors the resistance; our installation team will use these readings to reach the required load for each individual pile.
Quality Assurance.
Each pile is then topped with an underpinning bracket which sits under the existing foundation and a jacking system is then used to support the building in its existing position or in some instances with smaller buildings and conservatories this system can be used to slowly lift the building up to its original position. If design and calculations are required, the readings during installation will be logged and this will form the pile log which we will provide you with to confirm that the piles have been installed to the structural engineers plans and calculations.
