Raked Seating Floating Floors and Isolation Bearings, Union Square Aberdeen

Mason UK completed a project at Union Square Aberdeen, Scotland. This was a big project that made use of floating floors and rubber isolation bearings to acoustically isolate the raked cinema seating. This was one of the most complicated jobs Mason UK has ever undertaken.

We worked with BDP to help them achieve acoustically isolated auditoriums / cinemas. The complexity was in the raked seating structure.

Concrete Plinths & Void Formers

In the first photo below you can see the concrete plinths. These were used to place the jacks on. The gaps in between were filled with polystyrene void fillers (as you can see in the second photo). This was to act as a base for the poured concrete. Once the floors are jacked the concrete floors will not be in contact.

Floating Floor Construction

The first photo below shows the mesh and floating floor jacks laid out over the plinths and void formers. The second photo shows the cured concrete being jacked. Each level was poured separately but connected by reinforcing and later jacked as one.

Rubber Cinema Isolation Bearings

The steel framework of columns that support the raked seating area was isolated from vibration with Mason Industries LDS rubber Building Isolation Bearings. These are the very best products available in the industry.

About Union Square – Aberdeen, Scotland

Elastomeric Isolation Bearings

Elastomeric bearings can be made from a variety of materials and are very effective against most medium to high frequency vibration sources. The material choice depends on the environment, but natural rubber is the most common choice due to its low dynamic stiffness.

Isolation Bearings

Building isolation bearings are used to isolate entire buildings or elements such as walls, floor plates, or columns. Bearings are normally bespoke, designed to accept the specific loads and have the correct isolation characteristics.

Spring Isolation Bearings

Spring bearings are used to isolate against low frequency vibration sources and impact. They can be made using single or multiple springs and low natural frequencies of less than 2.0Hz can be achieved.

Jack-Up LDS Rubber Floating Floors

The Mason FSN Jack-Up acoustic floor system can be used as the crucial part of achieving box in box construction for studios or rooms requiring a high level of acoustic separation or simply providing acoustic or impact isolation from one area to another.

Concrete Floating Floors

Floating floors systems are used for many purposes, predominantly to prevent noise passing through the floor but also to isolate against vibration and impact.
