Foundations and Floors

The junction between wall, foundation and ground floor has to deal with structure, insulation, damp-proofing and often ground gases, all at once. This section covers trench and strip foundations, raft foundations and insulated foundation systems, ground bearing slabs, beam and block and suspended timber ground floors, intermediate and separating floors, and Passivhaus foundations and floors. Details span masonry cavity, timber frame, SIPS, steel frame, CLT, ICF and Porotherm construction, for new builds, extensions and conversions. The library holds 800+ details in total, in CAD, Revit and SketchUp.

Which Building Regulations apply to foundation and floor details? Part A for structure, Part C for resistance to ground moisture and ground gases such as radon, and Part L for floor insulation. Separating floors between dwellings also need to meet Part E (sound) and Part B (fire).

Do you have details with insulation above and below the slab? Yes. Ground bearing slab details show insulation above or below the slab, so you can compare the two approaches.

Which file formats can I download? Pro members get DWG, Revit, SketchUp, PDF and JPEG. Lite members get DWG. You can also buy single details.
