4 2 slab on grade construction details in this section several typical slab on grade sections are illustrated and described.
Concrete floor slab section detail.
Floor slab detail.
There are many approaches to insulating a radiant slab but the detail at right shows a frequently used method.
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.
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.
Figures 4 12 through 4 14 show variations where the slab is the primary location for insulation.
The ground floor is made up of suspended concrete slab or beam and block floor supported by the external and internal load bearing walls which transfer the loads to the foundations below.
Beam and block floor.
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.

Introduction a slab on grade is defined as any concrete slab poured over excavated soil.
