FSN Rubber concrete jack-up system uses the Mason jack-up system to raise a concrete layer using adjustable jacks. This system offers high levels of flexibility and guarantees an air gap. The bridge-bearing natural rubber isolators are unique to Mason. They are maintenance free, will last the life of the building and offer the best possible isolation performance of any known elastomer. This system can be used for recording, radio & TV studios, cinema auditoria, music rooms, gymnasiums and plant rooms. Air gaps of up to 200mm can be achieved with the jacking process or higher with the use of void former and plinths. Natural frequencies can be specifically achieved in the range of 8-12 Hz by the careful selection of isolator types and spacing. The elastomer used in the Mason system is now LDS (Low Dynamic Stiffness) rubber which is a recent advanced formulation and combines the advantages of the low dynamic characteristic of rubber with the longevity of bridge bearing neoprene.
