01 System installation

System installation

1. Foundation:

Ecotec System is assembled on a foundation layer made of natural or recycled material (i.e. concrete aggregate) of a grain size of 0-32 mm that has been mechanically compacted. The depth of the foundation is at least 0,3 m with its dimensions depend on the height of the barrier, which affects the width of the base.

Steel support construction

2. Steel support construction:

Steel construction consists of frames in the form of the letter “A” with built in thick-walled pipes and welded flat bars stiffening the construction. All steel components are made of fully hot-dip galvanized high-quality steel and are compliant with the standard PN-EN ISO 2178:1998 reaching surface thickness of up to 300 µm. All elements are made manually and individually adopted to each project accordingly to the barrier height between 0,15 and 10 m. Due to complete galvanization of the construction and no bolted connections, assuming an average annual loss of zinc equal to about 1 µm System can easily last up to 80 years.


3. Filling:

Once the steel structure has been set up, its interior is filled with earth material by means of an excavator or conveyor belt. The screen can be filled with any earth material with a grain size of 0-60 mm. The filling does not require mechanical compaction - the excess material is placed, which is used in the process of gravitational compaction (natural).

The majority of competitive systems of noise protection provide 5 to 15 years guarantee on the filling. Due to the constant characteristics of the filling material (earth), acoustic effectiveness of the System is not limited by time.


4. Planting:

The side surfaces are covered with various species of climate-resistant vines, and the top of the barrier is usually covered with rolled grass or sown with a mixture of wild herbs and grasses. The aim of planting is to receive a fully vegetated construction in the shortest possible time. Usually the barrier is fully covered by plants within 3 to 5 years.

Drainage or passage for small animals

Drainage pipes or passage for small animals, can be integrated in the system and do not require leaving gaps between the barrier and the foundation.

Light structure over installations

Mobile elements are mounted over underground installations and can be disassembled using a crane within a short period of time.

Emergency exits

Exit doors of various sizes, made of different materials in various colors.

Advantages of Ecotec System

  • The possibility of building in almost every ground conditions, also on muds and with high groundwater level
  • The possibility of installing lightweight sections which can be disassembled in order to access manholes; all construction elements are installed over the ground, immediate inspection is possible, as well as exchange of any mechanically damaged parts
  • Ecotec System creates a uniform mono-block barrier without any gaps or joints that perfectly stops the sound from getting to the other side
  • The possibility of immediate reaction to changes of the designed barrier location in relation to the project, even during the construction stage. Therefore, it can be necessary to change the course of sub-construction or its height
  • Optimum growth conditions for plants thanks to high volume of soil in the system, therefore, the barrier does not heat up and remains cold also in summer. During dry periods, filling serves as a reservoir of water for rootlets. A coconut mat used on the outer surface is perfect for climbing plants
  • It is not possible to get to the top of a barrier without using any tools - safe for children
  • Garden service for 24 months consist of exchange of plants which have not grown and removing weeds
  • No deep foundations - time and technical expenses saving
  • The possibility of crossing with underground installations while the whole construction is over the ground
  • A completely galvanized construction, assembled without screw and bolt joints in order to lower the risk of surface damaging so there is no risk of corrosion
  • An average zinc layer of 160 µm, with average annual loss of zinc at the value of 1-2 µm guarantees up to 80 years of durability without loss of static characteristics
  • Depending of the barrier height, very short assembly periods from 20 - 70 m per day with 4 workers
  • Drainage pipes can be conducted through the construction with low technical expenses and in a short period of time
  • Vandalism is basically excluded as nobody will cover plants with graffiti. Dirt on coconut mats is quickly covered with plants
  • The highest approval of residents, as the Ecotec System is not perceived as a technical construction, but as a part of a natural landscape as soon as it has been fully covered with plants
  • Ecotec System is approved by Deutsche Bahn, RENFE/Spain and SNCF/France.
  • The system has the Technical Approval of the Road and Bridge Research Institute (IBDiM Nr AT/2010-02-2599).

Advantages of Ecotec System

A perfect relation of price/quality/effectiveness:


Sound insulation:
DLR = 42 dB (class B3);
Sound absorption:
DLα = 12 dB (class A4);




Durability of the construction up to
80 years;


Guarantee period up to 40 years
for statics and the steel construction;


Lifetime guarantee of acoustic
effectiveness, as the filling does not
lose its volume and does not
change its characteristics;


Almost maintenance-free - extensive
planting provides constant covering
along with no need of removing
dirt either graffiti;


An excessive ground from the construction site
does not have to be transported as long
as it can be used for filling barriers
- 1 m² of a barrier requires about 1 m³
of soil for filling;
