First: Greenhouses
The current and future Saudi vision in the agricultural sector focuses on relying on agricultural greenhouses as one of the most important solutions to address water scarcity and the excessive depletion of water resources in traditional agriculture. This approach falls within the Kingdom’s efforts to achieve sustainable agricultural development, supporting national strategies and encouraging and facilitating the provision of agricultural loans to farmers for implementing greenhouse projects through the Agricultural Development Fund.
We hope that greenhouse projects will be able to create added value in the agricultural sector, which is the most important objective in the world of economics. Transforming these projects into an integrated industry could represent one of the most significant pillars of the national economy in the future, in addition to increasing the contribution of the agricultural sector to the gross domestic product (GDP).
It is not surprising to say that agricultural greenhouses contribute significantly to achieving a high level of food security in the Kingdom; moreover, in our view, they may represent the optimal solution for developing and reclaiming many of the barren lands across the Kingdom.
For this reason, we have taken part in the Kingdom’s agricultural development journey. Our organization has been managing greenhouse projects and their warehouses for more than ten years, supported by the launch of our greenhouse manufacturing plant, which designs and manufactures greenhouse steel structures using the latest programmed cutting and welding technologies, operated by qualified engineers and trained technical labor. In addition, we have partnered with several national and international companies to provide greenhouse requirements such as cooling, ventilation, lighting systems, and more. This has enabled us to deliver comprehensive solutions to our clients and meet their needs at competitive prices and high quality.

The company has also specialized in executing landscape and irrigation network projects for greenhouses, as well as planting trees and palm trees, using the highest quality locally manufactured and imported products.
الري بالتنقيط:
Drip irrigation is a system in which water is applied directly to the soil in quantities close to field capacity, in the form of small droplets delivered directly to the root zone. This system is distinguished by wetting only part of the soil, while other areas remain dry throughout the season. As a result, it provides many benefits with very few drawbacks.
Advantages of Drip Irrigation:
Promotes plant growth, increases crop yield, and reduces soil salinity problems in the root zone.
Improves and reduces the use of fertilizers and other chemicals, lowers labor requirements, and enhances agricultural operations.
Reduces weed growth and allows maintenance operations to be carried out during irrigation.
Allows the use of relatively saline water and can be combined with sprinkler or flood irrigation systems.
Enables the system to operate fully automatically.
Consumes approximately half the amount of water required for sprinkler irrigation.
Reduces fungal diseases since plant leaves are not wetted, making it highly suitable for desert lands.
Can be used in uneven areas with natural topography unsuitable for surface irrigation.
Reduces water loss caused by deep percolation below the root zone.
Artificial Grass
There is no doubt that modern technology in the field of petrochemical industries has contributed significantly to providing alternative solutions and materials for the agricultural sector. One of the most important of these alternatives is Artificial Grass.
Artificial grass is manufactured according to international standards to serve as an effective alternative to natural grass, maintaining its appearance and texture while avoiding the common problems and disadvantages of natural grass. Artificial grass is made of polyethylene fibers designed to closely resemble natural grass in both form and feel. In addition, it includes a mixture of silica sand and rubber granules, which enhances durability and provides a natural, realistic surface.
Given the scarcity of water resources in the Arab region, artificial grass has become an ideal solution for water conservation and maintaining green spaces. It is widely used in gardens, children’s playgrounds, chalets, sports fields, and recreational areas.
Recently, the demand for artificial grass has increased significantly, leading to the expansion of its marketing and the establishment of a dedicated department within the company specializing in the supply and installation of artificial grass across all regions of the Kingdom. This includes landscaping projects, parks, school playgrounds, as well as private projects such as villas, palaces, and resorts. We have successfully executed numerous projects approved by the Ministry of Higher Education and various other governmental and private entities.
Advantages of Artificial Grass
Helps conserve water resources as it does not require irrigation, eliminating the need for complex irrigation networks used with natural grass.
Flexible, easy, and quick to install, with no need for regular mowing or intensive maintenance like natural grass, saving time and effort.
Environmentally friendly as it does not require pesticides or chemical treatments.
Suitable for year-round use in sports fields and public and private gardens.
Resistant to sunlight and ultraviolet (UV) rays, as it is manufactured from UV-treated polyethylene materials.
Significantly lower maintenance costs compared to natural grass.
Reduces the spread of harmful insects often associated with soil cracks in natural grass.
Fire-resistant, easy to maintain, and has a long lifespan.
Can be reused multiple times and easily dismantled, relocated, and reinstalled at another site.
Can be installed on various surfaces such as concrete, sand, clay soil, or coastal areas, unlike natural grass which requires specific soil conditions.
