Concrete floor slab section detail.

Introduction a slab on grade is defined as any concrete slab poured over excavated soil. Top section back and apply the fab tape 4 back and parallel to the edge of the bottom section. Figures 4 12 through 4 14 show variations where the slab is the primary location for insulation. Floor slab detail.

It is also a. It consists of a series of slab thickenings under the walls with a minimum 12 deep downstand on the perimeter. The reinforced concrete floor slab is kept free of the perimeter walls. In typical office environments the concrete floor slab itself is comprised of 4 to 6 thick concrete reinforced with one layer of welded wire fabric at mid depth unless below the water table when hydrostatic heads may exert upward pressure requiring stronger construction.

Remove the release paper and firmly press the top section to the bottom while maintaining even tension on the material to avoid gaps which could cause leaks. Smooth out any gaps or voids while applying the tape. Figures 4 9 through 4 11 and 4 15 show configurations with insulation on the exterior surface of the foundation. Under slab vapor retarders or waterproofing membrane.

The footing is placed entirely on well compacted granular material. There are many approaches to insulating a radiant slab but the detail at right shows a frequently used method. It will cost only pennies if you can cut out the damaged section and reuse the tubing later in a floor joist application.
