Slovakia is located in Central Europe. In recent years, highway expansion and ecological restoration projects have been continuously advanced, keeping the demand for slope greening equipment stable. According to statistics, the local landscape gardening service market reached 111.6 million euros in 2026, with an annual growth rate of 4.9%.
Taking this opportunity, YG launched its small hydroseeding machine into the Slovakian market. Among them, the YG-4 model has been applied to the slope restoration project of D1 Highway in Bratislava, providing a reference for subsequent market promotion.

Case: Small Hydroseeding Machine Empowers Bratislava D1 Highway Slope Restoration Project
The detailed information of the project is explained point by point as follows:
Customer Background: The client is a highway contractor based in Bratislava, the capital of Slovakia. It undertakes slope restoration for an 8-kilometer new section of the D1 Highway, with a required greening area of about 35,000 square meters. The enterprise mainly takes on municipal and transportation projects with standard requirements for construction quality and construction period.
Construction Challenges: The slope is mainly composed of weathered rock and gravel mixed geology, with partial slopes exceeding 45 degrees, making natural vegetation restoration difficult. The contractor once tried artificial turf laying and dry grass seed spraying. Artificial turf laying is time-consuming with low efficiency for large-area construction, and the survival rate of turf on steep slopes is average. Dry grass seed spraying led to seeds being easily washed away due to frequent spring rainfall locally, resulting in repeated reseeding. Therefore, a piece of equipment that can adapt to steep slopes, resist rain erosion after spraying, and is easy to move was needed, so the client began to look for suitable hydroseeding machine for sale.
YG Solution: The YG team provided support in terms of equipment selection and construction technology.Equipment: The YG-4 small hydroseeding machine was recommended. It features a wide slurry pump flow channel that is not easy to block, and can convey slurry with high soil content. The equipped high-pressure nozzle can spray mixed materials to slopes above 45°.Technology: A soil-spraying greening method was suggested. Rice husk and sawdust were added to the slurry to improve the adhesion of the mixture at low cost and reduce seed loss caused by rain erosion.
Project Process: The client found the YG official website through a Google search engine. Initially, they worried whether overseas-purchased equipment could adapt to local climate and geological conditions. YG foreign trade staff provided equipment drawings, parameter sheets, and CE certification documents within 24 hours, and arranged an online communication. The spraying effect of YG-4 on slopes of different gradients and materials was displayed via video. Combined with Slovakia’s rainy spring climate, targeted adjustment suggestions for the ratio of “pulp + grass seed + adhesive” were given. After the client’s approval, the contract was signed within one week. The equipment was shipped by sea to Kosice Port in Slovakia, and YG provided remote installation and commissioning guidance.
Application Effect: Three months after construction, the originally bare slope has been covered with relatively uniform vegetation. After several spring rains, no obvious soil and water loss occurred on the slope. A single tank can cover about 1,000 square meters, and the 35,000-square-meter project was completed in about four weeks, greatly shortening the construction period compared with artificial turf laying. Meanwhile, according to customer feedback, by adjusting the material ratio, the material cost was reduced by about 20% compared with the original plan, saving thousands of euros for the project.
Customer Evaluation: The client said that this portable hydroseeder runs smoothly with satisfactory spraying uniformity, and mechanized operation greatly accelerated the construction progress. The equipment is durable overall without major faults during on-site use. YG’s after-sales service responded promptly, and remote guidance solved problems in installation and commissioning. The client affirmed this procurement cooperation.
Main Technical Features of Small Hydroseeding Machine Spraying Technology
YG small hydroseeding machine is suitable for construction on high and steep slopes like those in Slovakia, mainly due to the following technical advantages: First, it is not limited by regions and landforms with a wide scope of application. Second, the covering materials, adhesive, and seeds in the slurry are mixed evenly by stirring and then sprayed out, forming a seed-containing film on the soil surface, which reduces rain erosion and seed loss and ensures uniform vegetation growth. Third, sowing, fertilizing, and covering can be completed in one operation, saving working procedures compared with traditional methods. Fourth, high-pressure equipment can spray slurry to higher and farther slopes, making up for the limitations of manual sowing. Fifth, the soil-spraying greening cycle is short, and vegetation coverage can be formed in about two months, faster than artificial turf laying.
How to Reduce Cost by 20% by Optimizing the Ratio of “Pulp + Grass Seed + Adhesive”
In greening projects, material expenditure usually accounts for more than 60% of the total construction cost. To cut costs by 20% without reducing vegetation coverage, the key is not to buy cheap materials, but to realize precise proportioning based on local soil conditions.
- Localized Substitution of Fiber Materials: Traditional commercial wood fiber costs a lot. By optimizing the proportion, 30%-50% of local low-cost fibers (such as crushed crop straw, waste paper pulp, or sawdust) can be added. These materials not only meet basic covering performance, but also greatly reduce transportation and procurement costs, and increase soil organic matter content.
- Reasonable Dosage of Adhesive: Many constructors add excessive adhesive for safety, causing serious waste.
- Plain / Gentle Slope: Properly reduce the proportion of adhesive, and form a covering film by natural interweaving of pulp fibers.
- Steep Slope / Rock Slope: Polymer adhesive is necessary and should be used together with a water-retaining agent. The water retaining agent reduces irrigation frequency and saves labor and water costs indirectly.
- Scientific Mixing of Grass Seed Formula: Avoid using single high-priced grass seeds. Adopt the mixed sowing mode of “long-term effect + fast-growing” (such as tall fescue mixed with ryegrass). Fast-growing grass seeds can fix soil quickly and reduce the respraying cost caused by rain erosion. Experiments show that a scientific mixing ratio improves the early soil fixation effect, allowing a 10%-15% reduction in fiber dosage in the slurry.
- Mechanical Stirring Efficiency and Uniformity: Adopting a high-efficiency hydroseeding machine ensures even slurry stirring and avoids agglomeration or uneven concentration. Uniform spraying makes full use of every penny spent on materials, lowering the probability of local supplementary spraying and saving a lot of materials and working hours invisibly.
