Description
The SuperSleeper® is a composite polymer retaining wall sleeper that delivers serious performance without the weight and difficulty of concrete. At 200mm tall and 60mm thick, it’s designed to slot directly into SuperPost® composite C-posts for a complete, self-contained retaining wall system that any capable DIYer can install.
Unlike timber sleepers, SuperSleeper® won’t rot, split, or absorb moisture. Unlike concrete, it’s light enough for one or two people to handle without mechanical assistance. It’s the ideal solution for residential retaining walls, raised garden beds, and landscaping projects where ease of installation is a priority.
