The main differences include a decrease in the number of layers of the vegetation formation placed, the reduction in the weight of the formation due to the lower layer of the substrate and a greater ability to retain water in the formation. Ultimately, AQUADESK offers its users an extremely attractive price / performance ratio.

The AQUADESK material developed by us provides several functions in the vegetation formation. In the first place, it retains (accumulates) water for plant nutrition.  The whole structure is more solid (and less substrate is needed) as the roots grow into the textile desk. It also prevents the leaching of fine substrates, drains excess water and protects the material against damage.

AQUADESK is made from recycled textile materials of various sizes and functions. Its utility is mainly due to the suitable combination of the ratio of individual components. In addition to the already developed and tested material compositions, the development of new compositions using other types of recycled textiles continues.


A vegetative or green roof is a roof which is partially or completely covered with vegetation and soil or growing substrate planted above the waterproofing membrane. This roof can also contain other layers, such as a root barrier, reinforcing mesh, drainage or irrigation.

The main reason for the construction of green roofs is their positive influence on the environment inside buildings and in their surroundings. Green roofs reduce the overheating of air during the summer months, retain water, create oxygen, enrich the surrounding fauna and flora as well as aesthetically revitalize built-up sites, etc.

A green roof can be installed on both flat and sloping roofs of various types (e.g. a shed roof, gabled roof, hipped roof, compass roof etc.). The costs of installing a green roof and the difficulty of its subsequent maintenance depend primarily on its ground plan, division and slope.

A common green roof usually consists of a vegetation formation and a roof sheath, with the vegetation formation being understood to mean plants, soil (substrate), water retention layers and water filtration layers, excess water extraction layers and waterproofing film layers.

Basically, green roofs are divided into extensive, semi-intense, intense and biodiverse according to the planted plants, substrate height and maintenance requirements.

This is a variant of an extensive or semi-intense green roof with a varying substrate height, which can be partially or fully enriched with a local or similar soil component in terms of type. A biodiverse roof is planted with a large number of plant species, ranging from stonecrops to the original species of field flowers of the site.

This indicates a green roof with dry vegetation that can endure challenging to extreme conditions from the standpoint of exposure and weather as well as a lack of nutrients and moisture. In terms of the plant species, stonecrops, dry grass and herbs, houseleeks and dry mosses prevail. The substrate height of extensive green roofs generally ranges from 4 to 12 cm. Extensive green roofs are not watered. The roof formation must accumulate sufficient water in the substrate and in other layers.

It is a sort of „transition" between an extensive and intense roof. The height of the formation is usually between 12 - 30 cm. The semi-intense roof is planted with perennials and low shrubs. It places greater demands on substrate height, moisture and maintenance works, although usually not very demanding.

This type of green roof requires constant care and maintenance, just like a garden. It requires regular artificial irrigation and is demanding in terms of the composition of the formation. The substrate thickness ranges from a height of 30 cm. An intense roof type can be planted with almost any green. Actually, the only limit is the depth of its root system as well as the static load.

Depending on the type of green roof, basic maintenance works are carried out similar to those in gardens. Usually, these works aren't demanding, however, they still need to be done.  They are based on the occasional removal of natural seeding weeds and the inspection of drain elements (which has to be done on an annual basis anyway); in case of meadow grasses and herbs, the roof area should be mowed approximately 1-2 times a year and the mown material (depending on the intensity of the growth period) shall be removed. In the event of vegetation death, the respective places should be sown or additionally sown in order to avoid significant erosion (especially by wind).

It is possible to use soil from your own land or from the surrounding area, however, a consultation with an expert is necessary. According to the type of soil, it could be also combined with other materials. Its suitability for being used is set by its penetrability together with the type of roof that is planned to be constructed. 

If a green roof is designed as a walkway, it is possible to walk on the roof, both during laying and after it. An important factor is the use of materials resistant to walking loads - AQUADESK is such a material.
