In recent years, attempts have been actively made to plant plants on a large scale on the rooftops of buildings and other spaces, and to plant green spaces in urban areas.
In such a case, in many cases, a concrete layer of a presser foot is formed on a waterproof layer of a slab surface of a building or the like, and a gravel layer made of sand, gravel, etc. is used as a planting layer, Plants are planted by laminating layers one after another.

  However, in order to obtain sufficient water retention and drainage for plants, it is necessary to introduce a considerable amount of earth and sand into the waterproof layer, and the concrete layer has a considerable weight, so these weights have an adverse effect on the building. There is a problem of affecting. Therefore, the present applicant has previously disclosed a lightweight planting device excellent in water retention and drainage (see, for example, Japanese Patent No. 2531542).

Therefore, a part of the non-woven fabric must always be kept in contact with moisture held by the water storage means. For this reason, it is necessary to form the portion of the nonwoven fabric facing the water storage means with a soft nonwoven fabric to facilitate contact with moisture.
However, since the nonwoven fabric is located between the water storage means and the soil layer and is required to have a function of supporting the soil layer and partitioning the soil layer with respect to the water storage means, it is not preferable to soften the entire nonwoven fabric. It is desirable to form the portion in contact with the layer hard.

And in order to support a customer soil layer appropriately, a reinforcing material is further attached to a nonwoven fabric. This reinforcing material is composed of a net made of a metal or plastic material, and is fixed to the side in contact with the soil layer within the nonwoven fabric or on the surface of the nonwoven fabric.
