4 Road, rail and tunnel construction The construction of buildings next to underground railway systems requires, in most cases, a soft, resilient separation layer between the building and the tunnel. Selection of the appropriate isolation material depends on different factors, such as the speed of the trains, condition of the wheels/rails and type and thickness of the tunnel walls. Before determining which isolation material is most appropriate, it is advisable to take vibration measurements within the ground to record the amplitude and frequency to be isolated.

5 Regupol RAV200 Potsdamer Platz, Berlin Road construction For planners and engineers, Regupol and Regufoam provide a safe method of isolating roads and car-park decks. Regupol RAV200 was laid beneath the surface roads and pavements of Potsdamer Platz, to prevent the transfer of ground borne noise and vibration into a surrounding commercial development. Regupol RAV300 Underground railway Tunnel construction BSW supplies special rubber tiles for vertical isolation between underground railway tunnel walls and new buildings. Regupol and Regufoam are also ideal for isolating floor slabs in railway or tram tunnels. At the KappWeg Building in Berlin, RAV300 was installed to reduce structural noise near to an underground railway. Regupol resilient bearing Tay Road Bridge, Scotland Bridge construction An example of a simple method of vibration isolation. In this application Regupol was bonded to concrete beams. The image shows a Regupol resilient bearing beneath a concrete pedestrian walkway over a bridge length of approximately 2.5 kilometres. 5

6 Foundation isolation The vibration isolation of buildings is a complex task.there are a range of different solutions, depending on the nature, intensity and source of vibration. When a building is being planned near to a railway line, underground infrastructure or tram line, the ground borne vibration must be measured by a registered acoustic/vibration consultant prior to planning. Based on these measurements and the type of building construction, the isolation system can be designed. Controlling vibration next to railway lines 6

7 Paddington Central Regupol RAV100 was selected to isolate the concrete foundations of an eight-metre high podium deck from ground borne vibrations at a new business, retail and residential district in central London. To prevent train generated ground borne vibrations from entering into the main building structure, the acoustic/vibration consultant specified that the podium deck be isolated with a high performing anti-vibration material. This was crucial in order to eliminate structural noise and potential damage to the concrete foundations from trains soon to operate on the new track running directly beneath. Regupol RAV100 Isolating concrete foundations Motel One A range of Regupol materials were laid beneath a motel, to prevent the ground borne noise and vibrations from a neighbouring mainline damaging the building structure. The acoustic/vibration consultant specified that a natural frequency of 12Hz was required. As the building varied in its load distribution, it was necessary to use a combination of Regupol systems that would ensure uniformity of performance and other technical characteristics, such as deflection and creep. Isolated building foundations To achieve the specified performance, Regupol RAV100, Regupol RAV400 and Regupol RAV500 were installed beneath the entire area of the building, at a thickness of 34mm, 45mm and 45mm respectively. Foundations cast onto Regupol 7

8 Structural isolation DebiTel Building, Berlin Isolated floor In large buildings, there are many sources of noise and vibration, each of which must be assessed individually. Different isolation techniques are required according to where the source is located the advice will vary depending on the source of the problem, for example, whether it is a boiler on the first floor, or plant equipment located on the roof. Machine isolation Equipment generating dynamic forces must also be considered very carefully. For mixed use developments, floors should also be treated for impact noise as this will be transmitted in all directions through the entire structure of the building. As there are many factors to consider when attenuating noise and vibration, it is recommended that specialist advice be sought. 8 Structural isolation

9 Floating floors In this specialised field, Regupol or Regufoam can be installed to reduce impact and structure borne noise in areas such as residential buildings, offices, leisure complexes, cinema auditoria and bowling alleys. Floating floor Technical services and plant rooms Technical service and plant rooms are isolated against structure borne noise with Regupol or Regufoam using a simple plinth arrangement or cast foundation block. Such installations should always be designed in cooperation with structural engineers, as there are often several parameters which can contribute to the success or failure of vibration isolation. A typical example of an isolated plinth Roof mounted equipment Mechanical plant isolation 9

10 Industrial applications Early construction of an isolated inertia pit using Regupol Completed inertia pit, fully isolated Isolated inertia pit using Regufoam Isolation of a forging hammer Through its own dynamic forces, mechanical equipment generates noise and vibration.this can result in discomfort for the operative, and cause damage to the surrounding structure as well as the equipment itself. Remedial action post installation can prove costly and time consuming. As such, anti-vibration precautions should be considered early on in a project. Regupol and Regufoam anti-vibration products can be utilised to isolate noise and vibration at source and offer specialist and bespoke solutions, whether isolating pumps or lining inertia blocks. 10 High performing and with the ability to achieve very low natural frequencies, Regupol and Regufoam can be designed for a wide spectrum of applications.

11 Printing press isolation Installation of isolation materials Regupol RAV300 was used to isolate newspaper printing press foundations at one of the world s largest and newest print-works. Foundation anti- vibration treatment was required to prevent structural vibration and to prolong the life of the printing presses. 700 linear metres of Regupol RAV300 was installed around the foundation perimeter. This directly isolated five foundation blocks from the surrounding floor slab and supported a total of ten newspaper printing presses. CMS Vibration Solutions can offer a full technical service including bespoke solutions. Every project is dealt with individually, with the final material selection dependent upon many factors, including: Load Natural frequency Area Deflection Creep By reducing the passage of vibration into and out of the press foundations, the Regupol helped to protect the offices and building structure from excessive structural noise, along with isolating the press machinery from ground borne sources of vibration and shock. 11
