BACKGROUND OF THE INVENTION

Field of Invention

The disclosed subject matter is in the field of material for reinforcement of soil surfaces.

Background of the Invention

This invention relates to the reinforcement and development of soils, grasses, plants, and other vegetation. There are many different soils, climates, and geometric landscapes that make it very difficult to develop and grow grass or other plants and vegetation. Accordingly, landscapers try to apply seeds, fertilizers, or other technologies to promote vegetation growth. Traditionally, fertilizer is sprayed or applied to the surface of a landscape, but this approach leaves the fertilizer susceptible to be washed away and there is nothing to retain excess water. Moreover, many products used to promote vegetation growth have poor water retention or pliability. Additionally, some products are harmful to the environment and even toxic to humans.

Furthermore, in certain climates, there water is a scarce resource, so there is a need for a membrane that retains water and gives the soil the nutrients it needs for optimal growth of vegetation. Thus, this soil reinforcement membrane solves the problems of water retention and getting the correct nutrients to specific soils based on climate and geographic location.

SUMMARY OF THE INVENTION

In view of the foregoing, an object of this specification is to disclose a material designed for reinforcement of soil surface and topsoil.

It is another object of this invention to disclose a material to improve the development of grass lawns and landscaping.

It is another object of this invention to provide a material that is comprised of synthetic fibers that contain seeds and other nutrients and supplements for soil.

It is another object of this invention to provide a material that improves water conservation.

It is another object of this invention to provide a soil reinforcement material that is designed to adapt to numerous climates and conditions.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Disclosed is a soil reinforcement membrane.

FIG. 1 is a perspective view of the soil reinforcement membrane 100 with the upper layer 200 peeled back. In one embodiment, the upper layer 200 and lower layer 300 are made of synthetic fibers. In a preferred embodiment, the upper and lower layers 200,300 may be composed of 100% polyether or polyester fiber and they may have surface densities that range from 680 to 870 grams per square meter (“gsm”). Referring to FIG. 1, there is a layer of cultivating compounds 400 dispersed onto the lower layer 300. The cultivating compounds 400 dispersed onto the lower layer 300 may be seeds of perennial grasses, mineral fertilizers, biological fertilizers, slow release growth stimulators, moisture retaining components, and any other compound that may be used for vegetation. FIG. 2 is a perspective view of the soil reinforcement membrane 100 unrolled before application to a soil. The cultivating compounds 400 are specifically and selectively designed for different climates and soil conditions.

Referring to FIG. 1, the cultivating compounds 400 allow the soil reinforcement membrane 100 to be designed for biological recultivation of disturbed lands, sloped hills by roads and rail ways, embankments, ground surfaces of quarries and mines, and oil and gas pipeline routes. The soil reinforcement membrane 100 also protects slopes from erosion and gullying. The soil reinforcement membrane 100 may even be applied in boreal climates and promote cultivation of vegetation.

FIG. 3 is a cross sectional contextual view of the soil reinforcement membrane 100 applied between two layers of soil. FIG. 4 is a cross sectional contextual view of the soil reinforcement membrane applied between two layers of soil and promoting the growth of vegetation. In use, the soil reinforcement membrane 100 and cultivating compounds 400 will form uniform grass with a heavy root system, wherein the root system penetrates deep into the soil, binds subsoil, and creates sod, which produces high mechanical stability.

In one embodiment, the soil reinforcement membrane 100 is applied in dry weather conditions and when there is a positive air temperature on the pre-planned and smoothed out soil surface (i.e., sand, clay, loam, sand clay, silts). Soil chunks should be no more than 50 millimeters in size.

The soil reinforcement membrane 100 reduces the amount of water necessary to water the soil because the soil reinforcement membrane 100 traps water within it and conserves the water for use over time.

In one embodiment, the soil reinforcement membrane 100 may be manufactured on needle-punching machines. Referring to the manufacturing process, two rolls of geotextile material (i.e., polypropylene, polyvinyl chloride, polyester, or polyether) of different densities comprise the upper and lower layers/textiles 200,300. In a preferred embodiment, the geotextile material is either polypropylene or polyvinyl chloride, but the upper and lower textile 200,300 will be of the same material. In one embodiment, the lower textile 300, which may be used as the base, has a greater density than the upper textile 200. In a preferred embodiment, the lower textile 300 has a density of 250-300 grams per meter squared (g/m²), but preferably 300 g/m² and the upper textile 200 has a density of 100-150 g/m², but preferably 150 g/m². In a preferred embodiment, the upper layer 200 is less dense than the lower layer 300 in order to allow the vegetation to sprout to the surface. The lower layer 300 is preferably more dense in order to provide protection from potential obstacles (i.e., rocks and sharp objects). Also, a root system is more powerful, so it can more easily travel through the more dense lower layer 300.

To manufacture the soil reinforcement membrane 100, a mixture of cultivating compounds 400 (i.e., seeds, fertilizer, and water accumulator) are dispensed onto the lower textile 300 that is on a vibrating table, which allows the mixture of cultivating compounds 400 to be distributed uniformly. In a preferred embodiment, 60 grams of seeds of permanent grasses, 30 grams of perlite powder, and 15 grams of combined fertilizers are distributed for each square meter. All of these cultivating compounds 400 are uniformly sprayed onto the lower textile 300 from different dispensers. Once the lower textile 300 is covered with the cultivating compounds 400 and nutrients, the upper textile 200 is placed over the lower textile 300, fixed by two rollers, and placed onto a needle-punching table. Once on the needle-punching table, the upper textile 200 is sewn to the lower textile 300, wherein the needled plates punch the upper and lower textiles 200,300, preferably with a frequency of two punches per second. In one embodiment, the needled plate has 2,500 needles per meter squared (m²). The needle- punched textiles gives the soil reinforcement membrane 100 more flexibility and maneuverability. Accordingly, in a preferred embodiment, the synthetic fibers and needle-punched design allows the soil reinforcement membrane 100 to be manipulated in a manner that allows it to be applied to and conform to uneven slopes and a variety of other landscapes.

In one embodiment, the rolls of soil reinforcement membrane 100 can be installed on “prepared” soil, that is with the upper layer of the soil removed, or “unprepared” soil, wherein herbage will be formed at a later time, but the end results will be the same whether installed on “prepared” or “unprepared” soil. After the soil reinforcement membrane 100 is placed onto the ground, in one embodiment, the soil reinforcement membrane 100 will be covered with a layer of 10-15 centimeters of soil. Then, in one embodiment, the soil reinforcement membrane 100 is irrigated with five liters of water per meter squared every day for three days. After this initial irrigation period, the soil reinforcement membrane 100 no longer needs to be irrigated. In a preferred embodiment, after approximately six to seven days, grass will sprout to the surface and after 2-3 weeks, thick herbage and a root system is formed.

In one embodiment, jute or a nonwoven propylene mesh may be inserted between the upper and lower layer 200,300 to increase the strength of the soil reinforcement membrane 100. In another embodiment, the geotextile membrane may be biodegradable.

In a preferred embodiment, the upper and lower layers 200,300 will not have ruptures, cracks, or holes.

In a preferred embodiment, the soil reinforcement membrane 100 is manufactured of low toxic components that do not adversely affect the human body during contact with a skin's surface.
