If you have an unlevel house or building, it is more than likely you need (what is traditionally referred to as) house underpinning. 

Raise and Relevel specialises in a modern form of traditional concrete underpinning called polyurethane resin injection ground improvement and can provide the quickest, safest, cleanest and most effective underpinning.

If your house is sinking and/or have cracks in walls, contact Raise and Relevel to have one of our ground surgeons provide you with polyurethane resin injection underpinning cost advice.  

If your house is sinking, it is important to fix it right away to avoid the risk of further damage and potential safety hazards. 

What is the cause if your house is sinking or unlevel?

There are a multitude of possible causes for weak or unstable ground if your house is sinking or if you have cracking of walls. These include;

• Variation in moisture content making the ground unstable from either;
  • Excessive water, e.g. flooding or;
  • Sustained dry periods, e.g. drought or;
  • Damage to inground services such as a sewer or stormwater leaking 
• Weak ground from poorly compacted fill 
• Inadequate footings during the original building process
• Erosion from natural (e.g. flood) or unnatural events (e.g. burst water pipe)
• Tree roots which reduce moisture levels and cause the ground to shrink
• Vibration and/or nearby excavation causing the ground to weaken
• Overloading of the structural capacity of the house foundations 
• Deterioration of retaining wall or slopes causing the ground to collapse     

Raise and Relevel has house underpinning solutions for all the above that will minimise underpinning cost.
