Jumbo bag of washed riverstones for dressing edges and fire breaks within green roof systems.
It is a requirement of all green roof construction to add a riverstone border around the perimeter and at all areas where the green roof comes into contact with an occupied wall or parapet.
Objects such as roof drain outlets, rooflights and access channels should have a border of stones around them to prevent dirt build up causing blockages and prevent vegetation blocking light and access.
For commercial installations please contact Roof Giant regarding safety regulations and layout guidance.
This section is split into two parts, with advice about Wallbarn's pedestals range, as well as their green roof offering.
Pedestals
What are the advantages of pedestals?
They are quick and easy to install, offer improved drainage, protect the surface underneath and can be lifted at any time for maintenance.
How do I install them?
The pedestals are placed on a flat, hard surface, with no mechanical fixings required. They need to be placed on a structured surface, and shouldn't be placed on non-compacted earth.
Do they need to be fastened?
No, the pedestals are part of a suspended system, with the weight of the slabs/decking holding everything in place.
Green Roof
What is a green roof / modular roof?
Sedum or other succulent plants are grown in low-level substrates. Modular systems are grown in sections and can be lifted into place and joined together.
Do they need maintenance?
The plants are very hardy, but watering in extreme conditions is recommended. Dead leaves and vegetation should be removed at regular intervals, and a slow-release fertiliser can be applied at certain periods throughout the year.
