Vlaardingen – Broadening the Aalkeet-Buitenpolder watercourse

For the “Broadening of the Aalkeet-Buitenpolder watercourse” project, GKB Realisatie bv commissioned us to make nature-friendly banks using Aqua-Flora® rolls.

For this project a total of 167 Aqua-Flora® rolls (3×0.3m) were placed. The rolls were clamped between two rows of 1m long ø8cm stakes. Bundles of brushwood were used to fill the water depth. Apart from that, 3,000 Aqua-Flora® plants (4x4x8cm) were placed in the wetland zone behind the roll, towards the slope.

We also placed an anti-waterbird construction, both near the rolls and the plants. In addition, a two-year maintenance contract was concluded.

Species of plants used in this project;

Marsh-marigold (Caltha palustris)
Bulrush (Scirpus lacustris)
Purple loosestrife (Lythrum salicaria)
Flowering rush (Butomus umbellatus)

The first photo shows how the stakes are pushed into the ground by a small caterpillar crane on a pontoon. The second and third photos show the situation immediately after placement.
