One-stop shop for all groundwork

Groundwork? At Marel Loonwerk it is an important speciality. We have the right machines for all projects. Plus people who know all about dedication. We use the latest technologies to perform work with utmost care. And also in our planning. At Marel Loonwerk, we believe that agreements are made to be kept. Marel Loonwerk has the right solution for all kinds of groundwork.


Over the last thirty years, Marel Loonwerk has built up a wealth of experience in the levelling of ground for substrate growing, culture floors and ebb-and-flood floors. Our state-of-the-art levelling machines, with double receivers, enable us to fulfil your every wish: a flat floor, a floor with a slope, or a floor with a ‘roof profile’. Our use of the latest technologies means that you are guaranteed minimum tolerances. If you wish, Marel Loonwerk can also construct horse riding arenas.


Using a cultivator is an excellent solution for new-build, to break the hard ground to a maximum depth of 30 centimetres. This makes it easy to then further refine the soil with a tiller, and to level the ground. A cultivator is also used when preparing for soil-based crops, to break obstructing layers of ground and thus create a highly permeable growing stratum.


In order to obtain a finer soil structure in new-build projects, we use a tiller after the ground has been broken with a cultivator. A tiller is also used to make the soil finer for open-soil crops. This creates a perfect seedbed for the new plants. Marel Loonwerk has a wide range of tillers for different applications.


Shredding is an ideal way to eliminate the remains of the last crop. We have shredders to chop up the plants or the remains of the harvested plants that are grown in soil. 


To ensure the correct construction of culture floors, it is essential to have a good drainage channel to catch the surplus water for recirculation. This is work for the Marel Loonwerk specialists: we take care of the perfect construction of drainage channels in the culture floor. This ‘drain profiling’ can also be used for greenhouse growers who still use substrate growing on the ground.


Vertical, interlocking shanks or blades are used to finely grind the soil. This is a good pre-treatment to enable the ground to be optimally levelled. Rotovating is mainly an option if there may be some rubble in the ground.


Digging is a good technique to improve the permeability of ground strata. Just ask Marel Loonwerk: it’s work that we’ve done from the very start. The machines we use today are adapted to the requirements you impose for efficiency. Ground strata are dug to a depth of 30 to 50 centimetres. This quickly breaks up compacted strata that are disrupting the drainage. And if you use steam treatment at the end of the growing season, this becomes many times more effective.


To give the soil the finishing touch after earlier treatments, rolling is a good option. A roller compresses or rolls the soil to compact it. This process is mainly used for substrate growing, culture floors and temporary crops such as bedding plants and pot plants.
