Product Details

The Fastfit 11x21 Garden Building Floor Kit is a straightforward, cost-efficient base solution for Sheds, Log Cabins and Summerhouses.

This 11x21 floor kit uses a click-together panel system paired with a water permeable membrane. That membrane handles drainage directly beneath your building, drawing moisture away from timber and preventing weed growth at the same time. There is no concrete to mix and no curing period to wait through. The 300 Tonnes per square metre load capacity means even full Residential Log Cabins can sit comfortably on top.

Every panel is manufactured from 100% UK sourced recycled plastic. The material will not rot, warp or break down over time, making it a genuinely long-term investment you can lift and reuse if you ever move or extend.
