What is Underpinning?
Underpinning is a structural process used to strengthen and stabilise the foundation of a home or building by extending it deeper below ground level. The need for underpinning can arise from a range of issues, including tree root intrusion, stormwater drainage problems, leaking mains or sewer lines, climate changes and drought, earthquakes, or inadequate building design.
​
Adelaide is known for its highly reactive clay soils and challenging climate conditions. These factors can cause significant movement in the ground, leading to serious issues for buildings and infrastructure. Because every property is different, the cause and extent of foundation movement can vary greatly. That’s why it’s important to consult a professional to determine whether your home or structure requires underpinning.
​
At Complete Underpinning, we are dedicated to restoring the strength, stability, and integrity of your foundation. Fully licensed and insured, Grant and his team are equipped to handle residential and commercial projects, delivering timely, professional solutions for damaged or subsiding foundations.
