Product Details

The Fastfit 11x21 Garden Building Floor Kit gives you a level, stable base for your Shed, Log Cabin or Summerhouse at minimal cost and effort.

This 11x21 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 is more than sufficient for siting even full Residential Log Cabins.

Every panel in this floor kit is manufactured from 100% UK sourced recycled plastic. The material will not rot, warp, or break down with age, and the entire base can be lifted and relocated or expanded if you move or upgrade.
