Full-Surface Decoupling

In full-surface decoupling, the entire base plate is separated elastically from the building ground. The elastomer is either applied on a thicker foundation course or on a specially dimensioned supporting plate.

To achieve optimum efficacy, the foundation should be as rigid as possible. Since it is a full-surface installation, the isolation can be performed quickly and easily, and the risk of acoustic bridges is very low, too.

The building loads are distributed over a large area of the subfloor. The degree of rigidity of the elastomers is selected by taking the different compression ranges into account. As a result, fairly even deflection of the entire base plate can be achieved.

The base plate and the adjoining structural components should also be as rigid as possible so as to avoid vibration of the structural components and dynamically activating large masses of material.

Finally, the elastomer must be covered with PE foil for protection against concrete slurries.
