Stable Foundations for Sewer Lines

Sewer and drainage infrastructure becomes vulnerable when the ground around it shifts.

Stable Foundations for Sewer Lines

Restumping, sometimes called reblocking or re-levelling, is the process of replacing old or failing stumps that support a house. Over time, traditional timber or concrete stumps can rot, crack, or sink into the ground. When this happens, the house above begins to show signs of movement such as uneven floors, cracked walls, or doors and windows that no longer close properly.

We restump homes across Perth using our engineered Hexplate foundation system. Instead of pouring new concrete pads or setting more stumps, we install galvanised steel plates that spread load efficiently into the soil. This creates a stable, concrete-free footing designed to last the lifetime of your home.

FAQ

They are different terms for the same process: replacing failed stumps and re-levelling the house above them.

 
 
 

Hexplates are engineered steel footings that spread load more effectively, avoid excavation and curing delays, and are eco-friendly compared to concrete.

 
 
 

We plan for dewatering or sealed installation methods and select technologies that perform in damp or saturated soils.

 

Hexplate systems are engineered for long-term performance and are designed to last.

 
Often no. Many foundation / footing and stabilisation works can be staged around live services with short, planned isolations.
Yes. Our systems perform well in restricted sites and utility corridors where heavy plant access is limited.
We plan for dewatering or sealed installation methods and select technologies that perform in damp or saturated soils.
Where practical we stabilise soils, transfer load to new foundations and keep existing assets in service.
