Building a Retaining Wall
Building a Retaining Wall
Never built a retaining wall before? No worries, Jack’s got your back (and your backyard). If your yard is a little slopey or you just want to level up your landscaping, building a retaining wall is a solid way to hold it all together – literally!
Retaining walls aren’t just there to look pretty, they’re unsung heroes of sloped blocks, runaway soil and garden beds that need structure.
Jack will walk you through the whole process one timber sleeper at a time. Our hero for this project – thanks @ashs.backyardgarden is Jack’s Retain-iT range.
Grab your gloves, channel your inner tradie and let’s build something that’ll make your neighbour say, “Wow, who did your wall”?
Let’s dig in.
