Swift Foundation Raft

  • A complete foundation and raft system for garden buildings that is ready to use, quick to assemble, and comes complete with all materials and fixings.  It is suitable to support both buildings and decking.

    The timber frame construction of the raft will support a variety of timber-framed buildings especially self-build, self-assembly and DIY kits delivered in flat pack format.

    The Swift Foundation Raft is an alternative to using wet-mix concrete as the foundation for a garden building or portable building. Delivered in kit form designed for self-assembly, it is quicker to create and makes less mess than using wet-mix, whilst providing a strong, durable and level base for your building.

    • Swift Foundation Raft Benefits

      • A complete foundation and raft – comes complete with concrete plinths, weight dissipating grids, timber bearers and joists, plywood sheathing and all fastenings
      • Designed for self-assembly – pre-cast concrete, cut-to-length timber bearers and pre-hung joist hangers
      • Minimal excavation needed – largely a surface-mounted foundation to speed up installation, reduce the quantity of spoil and disruption to the site
      • Quick to install – simple step by step instructions and labelled parts make Swift Foundation Rafts quick to install and build upon
      • No waiting time – erect the building as soon as the Foundation Raft is finished – no curing time
      • Good drainage and ventilation – surface water drains naturally under the building; air circulates under the building extending the life of the timber
      • Height adjustable – 50mm of adjustment to each plinth bracket compensates for any minor ground unevenness
      • Portable – should you decide to move your building, you can dismantle your Foundation Raft and move it also
