This solution can employ insulation at the stem wall only which isolates the slab from the exterior side of the foundation but does not isolate it from the subslab grade. There is situation when we require a building extension without affecting the already existing foundation.

This avoids seepage of water and frosting. 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 acts a barrier between the superstructure and the ground. Rigid insulation is placed vertically on the interior face of the foundation wall and extends into the joint at the slab edge.

For this purpose the slab can be insulated. The width of these foundations is determined by the type of soil and this will be confirmed by the building inspector. These foundations involve pouring at least 250mm of concrete into the foundations. The floor slab is usually placed over the dpm.

The reinforced concrete floor slab is kept free of the perimeter walls. Discover and save your own pins on pinterest. Insulation may be placed under the slab as shown for additional thermal or condensation control. The footing is placed entirely on well compacted granular material.

A typical concrete mix for a ground bearing slab is 1 2 4 gen 3 mix. The mesh reinforcement in the slab is placed in the top with 1 covers. Foundation wall cast integrally with the slab as an edge thickened slab figure 1 constructed as a separate concrete figure 2 or concrete masonry figure 3 perimeter foundation wall with the slab laid later. The floor slab should not be less than 100mm thick.

Integral or separate slab construction was typically. This won t interfere with the building structures already built. However where there is a risk of sulphates of other harmful chemicals are in the ground a special concrete mix may be required. On to this base the block work is built up until ground level is reached where the materials are changed to your choice such as bricks.

This section of construction details includes. It consists of a series of slab thickenings under the walls with a minimum 12 deep downstand on the perimeter. Floating slabs behave as a barrier for the entrance of the moisture coming from the ground. Figure 4 13 illustrates a slab on grade foundation with a concrete masonry foundation wall.

Floating slab foundations are a good solution when comes to extension of houses. In 1978 nzs 3604 became the standard for slab on ground floors. Floor slab detail.
