Flood floor irrigation systems are the best option for growers producing seasonal crops, looking to reduce labor costs and improve crop quality. Enjoy consistently great crops and a virtually maintenance-free growing system.
Flood floor irrigation technology has changed immensely over the past 20 years. Advances in concrete technology allow for a shallower profile on the floors to create greater uniformity. Delivery and filtration technology have also improved.
Ask any greenhouse grower with a concrete flood floor built within the past 10 years and they will agree that they save a large amount of labor and enjoy consistently great crops and a virtually maintenance-free growing system.
Flood Floor Overview
Flood floor irrigation systems from Zwart are the best option for greenhouse growers producing seasonal crops, and for growers looking to reduce labor costs and improve crop quality.
- Traditional Flood Floors
These traditional system designs were developed in the 80’s and continued to be built along the same thought process until the late 90’s. V-shaped concrete floors are poured and water is introduced into the floor system from the center of the bay and is tied into a spur line that fills the floor. After the floor hits the desired depth the water returns through the same set of pipes and is channelled into the drain valve and drain pipe returning back to the tank area. This system is not often built anymore because of the large amounts of debris that can be stuck in the ends of the spur lines.
- Flow-Through Flood Floors
In the early 2000’s this floor design grabbed major attention. This system allows the water to enter the floor from the gable end of the spur line, fill the floor and then exit through the opposing end of the floor allowing the spur lines to be flushed at each cycle. It also allowed the grower to “hold” water on the floor if the grower desired a longer contact time for larger pots.
- Cascading Flood Floors
Developed by Zwart Systems in 2008 this product changed the greenhouse industry once more. Cascading floors are poured on an angle from one post row to the next, and water is introduced on the high side. Water flows across the floor allowing the grower to use short-run cycles to deliver a partial watering if required or a full watering delivery when required. The benefit of this floor is that the fill line never sees untreated water and the floor surface is cleaned with each cycle.

Zwart Systems flood floors are ideal for plant lay down using either robots or forklifts, and the concrete is a consistent surface for the crops. Coupled with an overhead boom and automated basket systems, the floor return system allows us to capture all of the excess water and filter it for reuse just as the floors do themselves. The return water system being filtered helps keep the floors clean and free of debris. We have connected the floors to our greenhouse environment control system which allows us to run them in an automated fashion. Zwart Systems flood floors are our preference to any other floors. We would not keep installing them if the growers and ownership did not see benefits regarding crop consistency and quality.
