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 Kapp Weg Building, Berlin

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.

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 Regupol® RAV100
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.

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. 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.

Structural isolation
Debi Tel 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. Equipment generating dynamic forces must Machine isolation
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.

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.

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.
