How building with jJack works

Top Floor Built At Ground Level - J-Jack Systems

1. The upper floor is constructed at ground level

  • Building the upper floor at ground level eliminates the need for working at heights.
  • Without scaffolding, cranes or hoists, the upper floor can be built faster and cheaper, together with greater safety and enables a better build quality.
  • We can even fit out many of the services and complete guttering and external finishes before lifting

2. The upper floor is lifted into place & supported

  • Using the J-Jacks, in just one day, the (externally completed) Upper Floor is lifted into place and supported.
  • The structural integrity which is engineered into the Upper Floor to enable lifting means for a highly resilient build quality with excellent rigidity.
  • Again, this produces time, cost and quality benefits compared with traditional methods.

3. The ground floor is built

  • Once the upper floor has been supported, your builder can build your ground floor. 
  • Our temporary braces are rated to more than 140 kph winds and many tens of tonnes which means your builder can work safely in shade and out of the rain under the top floor. 
  • Just like a normal single storey build, trades are able to work on both the bottom and top floor at the same time, further saving you money & time.

How we've revolutionised double storey building

The jJack building system was developed in co-operation with a number of highly respected and experienced companies. As a collective, when we looked at the biggest issues that affect the speed and cost of double storey builds, we found the following;

  1. Scaffolding, cranes and equipment lifts increase build time & cost by $20-30K.
  2. For builders, the scaffolding limits site space so materials have to be delivered on specific dates rather than being stockpiled. This creates project 'chokepoints'.
  3. Working at heights on the roof and top-floor is more expensive and dangerous.

Thinking outside the box, we have turned the construction process upside down by building the top-floor first at ground level and then using our precision, patented lifting system to raise it up and build underneath. This results in a higher quality, more affordable build as we can work on your roof and top-floor when it is easily accessible rather than working at heights. Additionally we have more space to work with and shelter from the elements so your house gets built faster and cheaper.
