Description
When installing a green sedum roof with sedum mats, a gravel edge between the sedum mats and the roof edge cannot be missed. The gravel prevents substrate and other small materials from ending up in the roof drain. Gravel also prevents clogging.
The properties of this 20 kg gravel bag
- Easy to use
- Comes in a 20kg bag
- Can only be ordered in combination with one of the sedum mats complete packages
- Ensures that no substrate or other small materials get into the roof drain
- 1 bag is enough for a strip of 2m long and 15cm wide
Using the gravel next to the sedum mats
We recommend putting a 15 to 20 centimetre wide gravel border between the roof edge and the sedum mats. With a 20 kilo bag, you lay down a strip of 2 metres and 15 centimetres wide on your roof.
