Magryn is currently involved in a relevelling project for a residential property in Adelaide’s northern suburbs.
The home is an L-shaped, 20-year-old brick veneer dwelling on a concrete raft slab had experienced significant differential settlement, with a fall of approximately 200mm across the floor.
The Engineering Challenge
Investigation revealed that plumbing failure around the home had led to ground saturation and subsidence, particularly in one corner.
As the house was built on a raft slab foundation, the entire structure tilted rather than cracking apart, resulting in minor wall and roof damage, but a very noticeable lean.
Engineering Assessment & Solution
Magryn undertook a detailed site inspection, assessed the extent of structural movement, and identified the underlying cause.
Our engineers recommended a relevelling approach using expanding urethane foam injection, a modern alternative to traditional concrete underpinning.
Execution
Specialists from Urathane Solutions were engaged to carry out the works. Using one of their larger mobile units, they established over 300 injection points across the property.
Their advanced equipment allows injection at depths ranging from 1.2m to 3.6m, reaching down to more stable ground and delivering a controlled, uniform lift.
What’s Next?
The jacking and relevelling works are now underway. We’ll share more insights, photos, and results in the coming weeks.
