If the height differences to be compensated exceed the capabilities of our SPAX Lift decking beams, they can be extended quite simply. Our product for this is called SPAX Lift Extension. This is a simple plastic ring with a height of 20 mm, 35 mm or 100 mm that allows the adjustment of the substructure to larger height differences. It is also possible to put several SPAX Lift Extensions on top of each other. This means for you: Almost limitless possibilities for terrace construction, especially on slopes no elaborate foundation for the terrace is necessary.
