Retentie Gully Box systeem

The Gully Box system allows water to infiltrate at a high level below ground level via gullies and gutters equipped with a debris filter. Loads of VK 30, VK 45, and VK 60 are possible, provided they are installed according to the installation instructions. The minimum cover dimensions (D) on the Gully Boxes, excluding the paving, are VK 30 (23 cm), VK 45 (29 cm), and VK 60 (35 cm). This is also the major distinguishing feature of the Gully Box system.
