From ProGrass to ProGrassFlex

The high-quality ProGrass honeycomb lawn protection forms the basis of ProGrassFlex. This ensures that the surface remains unsealed and that vegetation is able to grow lush over a large area. Optimal nutrient exchange is ensured by the structure and apertures between the cells of the honeycomb. During manufacturing, 3 panels are combined into a single standard element with the Flex-Clip. ProGrassFlex is delivered pre-packaged, depending on the profile and bed width required. Its low weight make the elements extremely economical to install.

Flexible

The pre-installed Flex-Clip hinge allows for movement between +90° to –90°. This provides enormous flexibility when it comes to installation of the product in a trench, trough or drain. It means that even terraced landscape structures can be flexibly and effectively protected against erosion.

Adaptable

Detail of an installation example with an extreme incline of approximately 30°. The infill material has a grain size of approx. 16/45. The detail diagram shows how well the elements adapt to the trench profile.

Expandable

The ProGrassFlex elements can be extended if needed by using any number of ProGrass panels. This means, for example, that the transition from a trench to an adjoining incline is easy to create.
