We remove asbestos safely and professionally. Are your buildings still equipped with asbestos-containing (corrugated) sheets? This can be unhealthy and dangerous. Let us remove the asbestos. Of course, we also arrange the demolition permit, draw up an asbestos inventory report and ensure proper planning. We then remove the asbestos safely, carefully and professionally. Ask us about all current government subsidy options. HG montage has been active in replacing asbestos roofs and renovating existing buildings for more than 10 years. We have all the knowledge, employees and equipment available to make an interesting offer and completely unburden you. You have also come to the right place for new construction. Are you interested in a total or partial solution? Then take a look at our total package!

We modernise every greenhouse, business space or shed complex so that it again meets current requirements and expectations. A renovation often rsults in energy savings. A small intervention can already result in big effect! We carry out all activities in-house and in such a way the production can continue!

Due to climate change, the foundation of the greenhouse has to endure a lot. Construction activities in the area, heavy traffic or other soil pollution can also lead to subsidence or cracks. We have all the knowledge and expertise in-house to strenghen, replace or repair foundations. We draw up a foundation plan based on laser measurements or extensive soil research. We will discuss these with you, after which our skilled technicians will start working while your cultivation continues!

Many of our innovations have been adopted by the market over the years. Jan Mienis, our company’s founder, over 50 years ago discovered how to retain the stability of reverse osmosis applied to well water. Nowadays this procedure is used throughout the world. Yet, Mienis’s reverse osmosis continues to make the difference. Over the years we gained a great deal of experience with different contaminants. We optimally use this knowledge to provide advice about new membranes, the right pre-treatment and the right chemicals, such as Anti-scalant. However, it is not always possible to prevent membranes from becoming contaminated. This is why we have developed a reverse osmosis system that is able to maintain itself through means of a Cleaning in Place (CIP) process. Cleaning modules, such as CIP, have been in existence for some time; however, Mienis is the only supplier that has fully automated this process. The system uses sensors to determine when a CIP needs to be started up and carries out the cleaning process independently. The systems we ship to Africa and the Middle East are equipped with this capability as a standard feature. It is of course better to delay a CIP as long as possible. Most of the contamination develops when the system is not producing. We developed a solution for this more than 50 years ago. Our systems may be shutdown for 6 to 12 months, after which they will start up again without any problems. By contrast, the systems of our competitors must be turned on for a short period of time every day in order to prevent the build-up of contaminants, with unnecessary energy consumption as a consequence.

Roam Eco Clean is a horticultural foam cleaner with an eco-friendly composition. With Roam Eco Clean, Roam Technology offers an ecological foam cleaner that is ideally suited for removal of organic deposits on a wide variety of materials in horticulture.

The Robot Plug Planter ensures a healthy plant that takes root quickly and develops a robust root system. The Robot Plug Planter is designed for automated planting of chrysanthemums. It places a soil plug into the ground instead of using press pots. A soil plug roots more easily, better, and faster than a press pot. A plug is more natural and peat-free. The plug is inserted into the soil without causing damage, which prevents root damage and helps the plant establish itself more quickly. A stronger start leads to a healthier plant and a shorter growth cycle, resulting in higher yields per square meter. Improved root development promotes more uniform growth and reduces failure or lagging, increasing the proportion of A-quality flowers. Plants are also expected to be less affected by Pythium, reducing or eliminating the need for pesticides.

The Roll-Air greenhouse was developed by us and is in use all over the world. The revolutionary feature of this greenhouse is the fully opening roof. Within seconds, your crop can be indoors or out, free from the effects of any shade. The Roll-Air greenhouse is an ideal solution because, unlike the standard Venlo convertible type greenhouse, it allows the grower to ventilate at all times, even in extreme weather conditions such as high winds.

ALWECO's roof roll screens have been specially developed for wide-span greenhouses, but have virtually the same properties and qualities as all other screen systems.

SAF‑XN filters are industrial, self‑cleaning metal filters manufactured by Amiad that can handle large amounts of dirt, which is automatically removed during filtration. Only a small amount of rinse water is released during the cleaning process. In addition, the filters are compactly designed, allowing them to be placed within a unit. The SAF‑XN series has been tailored, in collaboration with Netafim Netherlands, based on the needs and experiences of the Dutch greenhouse horticulture market.

The vacuum and overpressure safety valve by PRESSCON is a mechanical valve that provides protection against a vacuum and an overpressure inside a tank. It is designed to be as reliable as possible by using well-known and uncomplicated mechanics. The safety valve is available as an vacuum-overpressure safety valve and as a vacuum only safety valve.

The INDO element is an innovative new LED fixture for the (greenhouse) horticultural market, which uses Direct Drive® technology. While other LED products require frequent driver replacement, the INDO element does not have a driver. This offers customers a large number of advantages over other luminaires, namely: a longer lifespan, higher light output, lower weight and no maintenance. Because LED radiates less heat than current HPS lamps, it offers the possibility to control light and temperature separately from each other. With this LED lighting for horticulture there is more control over the growing conditions.

INDO TopLink is a professional horticultural lighting system, developed based on the proven INDO Element architecture with unique Direct Drive® technology. This eliminates the need for external drivers, increasing reliability and maximizing lifespan. The fixture combines high light output with a compact, robust 10 kg housing and is designed for continuous operation in demanding growing environments. Because the electronics and system architecture have been designed and coordinated by a dedicated team of INDO engineers, the INDO TopLink operates as a single, optimally integrated lighting system. This delivers a level of efficiency and stability that is unparalleled in the market.

De INDO Verti Link is een gloednieuw aanbod voor de tuinbouwmarkt. De Verti Link is een (glas)tuinbouw armatuur met 5 jaar garantie, uitstekend voor vertical farming.

You can contact us for a great diversity of types of glass, glass colors and of cours for difficult dimensions. We are also happy to provide you for the materials for the ventilation mechanism, screen installation, foundation and the greenhouse system. Thanks to our many years of experience in the field, we know exactly which part best suits your situation.

The SandStorm+ sand filter from Netafim is a carbon steel filter with a double‑layer coating that provides protection against corrosion and harmful UV radiation. The filter is equipped with double‑chamber technology, with the nozzles integrated into a bottom plate. In addition, the filter contains an increased number of nozzles, resulting in lower pressure loss. The nozzles are designed with a narrower slot width. The SandStorm+ sand filter is constructed from specially selected materials and has undergone specific treatments to ensure that the metal is optimally protected by the double‑layer coating. As a result, SandStorm+ contributes to long‑lasting, reliable, and uniform water delivery and is highly suitable for Dutch greenhouse horticulture.
