All types of JACK SUPPORT are guaranteed to bear concentrated loads of 400 kg each. A 400 kg concentrated load means an evenly distributed load of 1600 kg/sq m for 50×50 cm tiles and 2,500 kg/sq m for floors made up of 40×40 cm tiles. The maximum load recommended on each single piece is 400 kg, from which the safety coefficient, equal to 50% of yielding or breakage resistance, has already been deducted.
The jack support has been designed for the installation of any type of flooring on any surface, allowing inspection of the various systems beneath, without needing to demolish anything. We recommend to use slope correctors to grant loads at right angles to the laying surface. Just in this way a height load resistance will be assured.
