Preserving Your Retaining Edges

Making sure that your retaining edges last as long as possible is crucially important to your installation, especially when working with raised garden beds and planter beds. Because you’re constantly watering your plants, the steel will be constantly wet on the inside of your line. There are multiple methods of improving the preservation of your project, there are some ideas below:

Drainage
The main issue is drainage, how will the water easily drain from behind your retaining wall? Water weighs 1kg per liter, meaning that if you have lots of water building up behind the wall it will be under significant pressure. Given enough time, this pressure can cause your retaining wall to twist, buckle or even fail completely.

Water Penetrability
Another important factor in preserving your larger FormBoss™ edges is water penetrability. If steel is constantly wet (especially corten), it can start corroding and may not last as long as you would like. This can be avoided by painting on a bitumen backing/ in the inside of your edge (where the moisture will be). Another option is to use a good geotec fabric as a physical barrier.

Consult an Expert
It is generally best to consult a landscaper or architect about your specific project. All applications differ slightly, and they will be able to offer you the best advice possible specific to your project.

Take a look at the diagram below to get idea of some simple drainage options:
