Wave Lenzburg, Switzerland

DAMTEC® Bau

Welle Lenzburg Schweiz

 

1. Project

In Lenzburg, an apartment complex was built near a railway line. The emission forecast by the building physics experts of the engineering office Grolimund + Partner showed that the apartment complex must be a partially elastic bearing foundation in order to comply with the legal noise and vibration limits. On the basis of this investigation, a partial building foundation was planned. Parts of the building were mounted elastically on different DAMTEC® vibra types depending on the expected loads.

2. Installation

DAMTEC® vibra soft, hard and 3D are rubber granulate mats that reduce the transmission of sound and vibration for buildings and in civil engineering. Depending on the requirements, DAMTEC® vibra products can be laid in one, two or three layers.

Installation procedure:

  1. Cleaning the surface from stones
  2. Avoiding structure-borne sound bridges; screed and concrete must not get into the insulating underlay
  3. Cutting and installing edge insulation strips
  4. Rolling out DAMTEC® vibra; the covering should acclimatize for at least 24 hours
  5. Covering mat joints with adhesive tape to avoid sound bridges and displacement of the mats
  6. Laying PE foil; pull it completely up over the insulation strips to above the finished top covering height and then fix in place
  7. The screed or concrete can then be installed in accordance with the applicable standards and regulations
