Lawn grids
Lawn grids are mostly made of concrete or plastic and have honeycomb-shaped spaces that can be filled with soil and planted by sowing.
Lawn grids are used for the structural reinforcement of traffic areas that are walked on, driven on and at the same time greened. Typical applications are garden paths and sidewalks , fire service driveways, driveways and parking areas .
In concrete grids, the proportion of the plantable floor area is often less than 50% of the total area. Plastic grids get by with much finer bars so that the perforated area is well over 50%.
In addition to the visual effect, almost as much rainwater can seep away on surfaces paved with lawn grids as on grassland , which counteracts the problems associated with surface sealing .
history
The lawn paver was invented by Josef Metten in Bergisch Gladbach and registered as a utility model on November 27, 1969.
use
The surfaces paved with lawn grids are suitable for occasional use as a traffic route for motor vehicles without the development of deepened lanes. In addition, the grid provide a good friction and allow the infiltration of rainwater to.
By using lawn grids, fire brigade entrances can be created on green courtyards without having to create traffic areas with a closed ceiling.
There are many areas of application, especially for grass grids made of plastic. Special systems are offered for use in equestrian sports , in agriculture or in civil engineering . With ground anchors , lawn grids can also be attached to embankments and bank zones in order to prevent the top layer of soil from slipping off until the vegetation grows.
When parking spaces are temporarily set up on green spaces for major events, the access roads are often temporarily laid out with grass grids to prevent the meadow from being trodden on and disintegrated in wet weather.
When laying paths on flexible subsoil such as floodplain, marshy and sandy soils, new types of geotextiles can be used instead of grass grids , which are woven, sewn or welded into three-dimensional honeycomb grid structures.
