Roundabout / slope blocks
Roundabout/slope blocks can very well be used as a center island in a roundabout. An increased area that can be driven over is created, which leads to a lower average speed and increased road safety. Due to the shape and strength of the blocks, heavy traffic does not cause damage to the raised platform.
Grass concrete tiles in roundabouts
Grass concrete tiles on the entrances and exits of roundabouts prevent potholes from forming due to incorrect cornering. Placing grass concrete tiles in the bends creates a natural, safe road widening so that these potholes no longer occur.

The advantages:
- Road safety
- Easy to maintain, green and sustainable
- Promotes flow
- Cost-efficient due to fast installation
- Taxable for traffic up to and including traffic class 60
Roundabout concept applications
The roundabout concept can be used for standard, turbo, egg and jib roundabouts, among others.
Roundabouts "Sustainably safe"
By applying the CROW guidelines, a uniformity of roundabouts is created that meets the vision of “Sustainably Safe” traffic.
The “Sustainably Safe” vision is about road safety and aims to prevent accidents and virtually eliminate the risk of serious injury. “Sustainably Safe” is about the entire traffic system. These guidelines also contribute to better traffic flow.
