Hidden precision.

Quality that cannot be seen at the first glance.

The incorporation of elastic bearing layers requires special know-how. Ball bounce, resilience and evenness are just some of many factors.

How it works

The elastic bearing layer under the artificial turf ensures that the force reduction on the artificial turf is provided. Generally the force reduction measured on the artificial turf’s surface should be between 45 to 65 per cent. The lower figure applies to hockey, the higher figure to football. According to the football players questioned, figures of about 60 per cent were perceived as ideal.

Besides force reduction, there are further requirements for bound elastic bearing layers and elastic layers which are listed below:

Requirements

Sport functionality requirements

  • Force reduction
  • Evenness
  • Ball bounce

Technical Requirements

  • Dimensional stability
  • Wear resistance
  • Torsional strength
  • Slope

Installation

Elastic layers or elastic bearing layers are usually manufactured in-situ and applied on a bound or unbound bearing layer. Nowadays the layer thickness varies between 25 and 35mm. The thinner the layer, the more decisive the precise and consistent manufacturing of the layer is. Therefore the layer’s foundation has to be perfectly even as well. Work of this precision can only be achieved with laser-controlled machines.

The elastic layer consists of a mixture of rubber granulate and elastic binding agents mixed in-situ in a pugmill mixer. Mineral constituents are added to achieve greater stability.

The elastic layer can also be built by installing prefabricated turf lengths. If this is the case, it is important to select a layer thickness that ensures the required force reduction on the surface of the turf.

Why we are ahead

Technology

Our competitive lead in the area of elastifying layers stems from our automated processes, forward and at the same time flexible planning and especially from innovative special-purpose machines, some of which have been developed by us.

Evenness



The laser-controlled installation of the underlying gravel-bearing layer and uniform compaction of same provide absolute evenness of the elastic layer. 

Consistent compaction

 

We achieve uniform compaction of the elastic layer thanks to our specialised 2-screed technology. This technology involves pressing the material twice. 

Engine smoothness

 

The integrated electric motor guarantees exceptional smoothness of the engine and therefore absolutely constant working conditions.

Speed

 

We achieve the working speed we are known for through forward planning, optimised processes and cutting-edge technology.

Components

 

We only use tested material for our elastic layers to avoid problems like separation due to freezing or variation in quality.

Mixture ratio

 

The individual components are mixed using electronically controlled pugmill mixers that ensure that the material is absolutely homogeneous.
