Concrete Floating Floor Installation for Gym Free Weights Vibration Control – Mason UK Ltd

This video from our team at Mason UK includes a detailed explanation of the vibration control characteristics of our concrete floating floor systems and how they perform, whilst highlighting the excellent design and also going through the entire installation process. The Matt Roberts Personal Training in Grosvenor Square, London, was a functioning facility when Mason UK were contacted. It was apparent that the existing acoustic treatment was not sufficient to take out all vibration from the occupants, especially the low frequency “deep bass” vibrations. The structural floor itself was too flexible and transmitting these vibrations into the structure, disturbing the other residents. It was necessary to treat the room with further noise control and vibration isolation. The one-to-one personal training facility included an area for heavy weights training. This area was the main culprit in vibration transmission. Mason UK proposed the FS Sprung Jack-Up Concrete Floating Floor for this area. This system enables a floating floor to be supported on coil springs to effectively absorb the low frequency impact vibrations. The area was a difficult “horse-shoe” shape, but Mason UK were able to shutter the area to be able to construct the floating floor. In the above video, our floating floor expert, Tom, goes through all the aspects of constructed a floating floor. The steps are outlined below: • Once the floor area is clear, the jack-up mount locations are marked out on the structural floor. • Polythene bond breaking material is laid down. • Temporary and permanent shuttering is installed to act as the form for the concrete floating floor. • Perimeter isolation material, Mineral Wool is placed up against the bounding edge to give a soft joint to retain the isolation break. • The jack-up mounts are placed down on the marked locations, typically at 1200mm to 1400mm centres. • Reinforcing bars are situation on the external lugs or the jack-up mounts and tied in place. • First layer of mesh reinforcing is laid down with a 400mm overlap. • Spacers are used to space up the next layer of mesh. • Second layer of mesh is placed down, and all reinforcing is tied together. Two layers are required as the floating slab will be loaded from both the top and bottom. • The concrete is then poured onto the reinforcing to the desired level. • After the concrete has cured enough, typically 2 to 3 days, the tops of the jack-up mounts can be revealed, and the lids and inner threaded inserts can be removed. • The coil springs are then placed into each jack-up housing. The springs are selected for each mount location to take the expected loading and meet the required acoustic specification. • The threaded inserts are then screwed back into the housings, and the floating floor is lifted by means of a T-bar. The threaded inserts are turned 2 turns at a time in sequence over the entire floor, repeated until the desired air gap has been achieved. • A final level survey is carried out and any fine tuning will take pace. • The mounting lids are reinstated, and grout is used to cover the castings and give a level slab finish. The project was a great success. The owner, Matt Roberts expressed his gratitude and happiness towards Mason UK, professing that they are the experts in their field. Please note that hard hats were not a PPE requirement on the site as there were no overhead works. All works were carried out following strict COVID-19 guidance at the time of construction.
