Underpinning is a solid foundation laid below ground level to support and strengthen a building or home. The need for underpinning can arise from various issues including tree roots, stormwater drainage issues, mains water or sewer leaks, climate and droughts, earthquakes, inadequate building design and more.


Adelaide is known to have some of the toughest combinations of highly reactive clay soils and climate in Australia which can cause major problems to building and infrastructure. While there are many causes, the need for Underpinning can be dramatically different for each building and home so make sure to consult with a professional when deciding if your house, building or structure is in need of a underpinning solution.


We are dedicated to helping you fix the integral structure and stability of your foundation. Fully insured and licensed, our team of professionals are ready to handle any residential, commercial damaged or subsiding foundation in a timely and professional manner.
