A drainage mat is used to prevent the different layers of soil from mixing. In this way, you can separate gravel and sand cleanly, which can be an advantage when building a terrace, for example. In this article you will find out what you should pay attention to when buying and laying a drainage fleece.

This drainage fleece also impresses with its positive product properties and the wide range of possible uses. The mechanically bonded nonwoven consists of 100 percent polyester (PES) and is therefore non-rotting and weatherproof. The material easily withstands temperatures between minus 40 degrees Celsius and plus 80 degrees Celsius, and it is also UV-stable and water-permeable. You can therefore also lay it as a weed fleece under beds and borders and use it as a pond fleece.
Purchase Criteria
possible uses
Drainage fleece is inserted as a separating and filter layer between different soil layers if they should not mix. This is necessary, for example, when building paths and paved areas, under the terrace, under the green or flat roof, etc. In addition, the material can also be laid as a protective fleece between the floor and the pond liner when building a pond to protect it from cracks and damage. In addition, drainage fleece is also often advertised as a weed fleece, but you should use special weed fleece for this purpose.
material
Drainage fleece is usually laid underground, which is why they have to be made of rot-proof materials. Otherwise, you could tear up your newly built paths or paved areas after just a few years because the substructure won't hold up. Rot-proof drainage fleece is made of plastic, primarily polyester (PES). Non-woven fabrics made from this material are also weather-resistant and can withstand both extreme heat and frost. For fleece that is laid close to the surface - for example when constructing a pond - you should also pay attention to the UV resistance, since UV light causes many plastics to become brittle and brittle over time.
grammage
The term grammage refers to the weight of the nonwoven in grams per square meter and thus also indicates its thickness. Drainage fleece is available in different strengths, which are particularly suitable for certain purposes:
- under planted beds and borders: 50 grams / square meter, rots quickly
- under beds and borders, under gravel gardens: 100 grams / square meter
- under paths, rock gardens and sloping surfaces, even with heavy weed growth: 150 grams / square meter
- under trafficked paths or other heavily used areas: 200 grams / square meter
If possible, do not lay drainage fleece that is thicker than 150 grams per square meter. These very strong materials will not allow moisture or air to pass through, causing the underlying floor to rot over time.
size
Drainage fleece is usually sold in rolls so you can cut it yourself as needed. The roll length is between 20 and up to 300 meters, the width is usually only one to two meters. From this you can calculate how many square meters of area you can cover with one roll. So before you buy, measure the area exactly so that the material is sufficient. Take into account that the edges must overlap by a few centimeters when laying, so that the fleece does not slip.
water permeability
In contrast to foil, which actually has to be impermeable to water (otherwise the water would run out of the pond, for example), drainage fleece must actually be water-permeable - otherwise you would quickly have a problem with water drainage on larger paved areas or on a flat roof when it rains to have. Quite apart from that, it is extremely negative for the soil if it cannot breathe and is not moistened. In this case, the earth rots and can be completely replaced if the path or area should give way to a garden - all life in it would have died.
youtubefrequently asked Questions
Where does it make sense to lay drainage fleece?
Drainage fleece is very versatile and is particularly suitable for these areas:
- under gravel paths, slab and paved surfaces
- under the terrace, when sealing the basement
- under the sandbox, the raised bed or the sports field
- when building a riding arena or paddock
- as a protective and drainage layer around the house
- for the construction of (heavy) traffic roads and areas
Does drainage fleece also help against weeds?
Depending on the grammage, drainage fleece can also be used as a weed fleece, but this is not the primary purpose. Due to the special processing of the material and its properties, you should preferably lay special weed fleece under beds and borders, as this provides good protection against weeds, but is also more permeable to water and air.
How do you lay the drainage fleece correctly?
Always lay the drainage fleece in such a way that the ends of the individual strips overlap by around ten centimetres. In addition, material for handling should always protrude laterally, this is only handled before closing with the excavation or similar. You should also pay attention to a gradient of two to three percent when setting up, so that seepage water can seep in as desired or run into the sewage system.
Which drainage fleece is the best?
There are many manufacturers who offer high-quality drainage fleece. With products from brands like
- DeRiTex
- GardenMate
- planting
- stretcher
- HaGa
- or Aquagard
you basically can't go wrong.
Where can you buy drainage fleece?
You can get drainage fleece from Amazon, but also from hardware and garden stores. Specialist stores such as Obi, Toom, Hagebau, Bauhaus or Hornbach etc. offer a large selection in both stationary and online retail.
Can I also lay coconut drainage fleece?
In the past, drainage fleece was actually made of coconut fibers, but these rot after a while and only last a short time. Plastic materials such as polyester or so-called geotextile fleece have better product properties and also a longer service life. Even from an ecological point of view, nonwovens made from coconut fibers are not necessarily better.
