Field of Application

A gravel lawn is an area that is suitable for occasional use and is grassed over with grass. It means a closed lawn surface with only a small proportion of visible stones.

 

Within the scope of planning, it must be checked which construction methods are to be used in each case. 

 

The following construction methods are distinguished for areas with gravel turf:

  • construction method 1: areas exclusively for car traffic
  • construction method 2: same as construction method 1, additionally with low truck and bus traffic
  • construction method 3: as construction method 2, but with higher truck and bus traffic

The expected truck and bus share must be determined on a case-by-case basis.

 

For gravel lawns, this results in the following standard construction methods and guide values for the thickness of the vegetation base layer:

  • standard construction method SR 1:
    single-layer structure,
    15 - 25 cm high vegetation base layer
  • standard design SR 2:
    single-layer construction,
    25 - 30 cm tall vegetation base layer
  • standard design SR 3:
    two-layer construction,
    20 cm high vegetation base layer with base layer as subsoil

 

interground Schotterrasensubstrat 0-16 is suitable for the following areas of application: 

  • occasionally used parking areas for car traffic and low truck and bus traffic
  • alternative areas along roads
  • standing and movement area for the fire brigade
  • passable green strips of service and residential roads
  • little used paths for vehicles
  • agricultural and forestry roads
  • irregularly used event locations
  • campsites
  • garage entrances or parking spaces
  • pedestrian areas
  • base layer under lawn grids

Application

Gravel Lawn Substrate

If the lawn is also to be driven on, the constructional requirements must also be taken into account to achieve high track resistance and load-bearing capacity.

Gravel turf combines the positive characteristics of gravel and grass. Where pure lawn is already ruined after being driven over by a car, gravel turf shows its strengths. It makes it possible to design paths that can be driven on by vehicles and which are at the same time green and look good.

 

Gravel turf shows the following advantages:

  • cost-effective production
  • very easy-care lawn shape
  • only 2-4 cuts per year required
  • no infiltration shafts necessary
  • relief of the sewer system
  • greening with species-rich grasses possible
  • new habitat for plants and small animals
  • pollutant filtering effect by the soil organisms
  • contribution to environmental protection

Gravel lawn is the alternative to a paved area, much cheaper than paving, unsealed and green all year round. It consists of a mixture of humus and gravel of different grain size. This type of surface allows for the percolation of precipitation over a large area, in contrast to sealing the ground with asphalt or concrete. Water can seep through the gravel, and the necessary stability is achieved. The humus guarantees a good breeding ground.  

 

Gravel lawn is the ideal subsoil if you need a resilient green base.

It is essential to consider the conditions of the location so that the lawn grows well. The subsoil must be permeable to water but also be able to store water well. Furthermore, the soil must be well rooted and rich in nutrients. Moreover, the area should have as little slope as possible.

 

Depending on the soil conditions, a single-layer or two-layer structure is chosen.

In simple conditions, a single-layer structure is achieved by excavating a 10 to 15 cm layer of gravel lawn. To increase the load-bearing capacity, an additional 20 cm thick foundation of compacted gravel is often prepared. For heavier loads, a two-layer construction is recommended. 

 

Due to the water permeability, special grasses for gravel turf should be used for greening.
