This is what the underside of the cabin looked like before the smartjacks
As you can see here, the cabin is being held up by a concrete slab
Concrete slabs for the smart jacks
These concrete slabs will allow for optimum support from the smartjacks
The smartjacks were then installed into the concrete slabs. They are made of strong, corrosion-resistant, galvanized steel.
Another angle of the smartjacks
The smartjacks wont develop rust, so they will remain adjustable for years!
