Hello, I am looking for someone to write an article on Structural Foundation Slab. It needs to be at least 1250 words. The floor finish for all the floor does not include exposed concrete surfaces. rather, floor coverings including wood, vinyl floors, and carpets are used in the floor finishes exposed region. Additionally, the adhesives used in the application of floor coverings are sensitive to moisture requirements of the use of a waterproof system or long drying durations where poly vapor retarders are used. The concrete floor slab comprises of a 4″ to 6″ thick concrete reinforced with a layer of welded wire fabric at mid-depth.
The under-slab vapor retarders include polyethylene, polyolefin, high density bonded polyethylene, and asphalt composite/polymer modified sheets. Poly sheets are 15 mils thick and have taped seams, edges, as well as penetrations. The vapor retarders were selected as per ASTM E 1745 and E 1993 and installation and inspection are to be based on ASTM E 1643.
This section describes each floor and provides a schematic drawing of its structural Support, Environmental Controls, Finishes, and Distribution system in relation to the below-grade enclosure floor slab elements. The exterior environment, to which the floor slab is subjected, includes environmental regulated loadings including thermal, moisture, insects, as well as any soil gases. The interior environment to which the floor slab is subjected includes environmental control loads like thermal and moisture. Performance of floor slab system heavily depends on the slab’s ability to control, regulate, and moderate the environmental control loads on the floor slab interior to desired levels.
The key objective was to avail a waterproof membrane/vapor retarder below the floor slab. A vapor retarder can resist vapor migration in absence of hydrostatic pressure. Water-proofing helps in resisting both vapor migration and hydrostatic pressures. Generally, the vapor retarder is installed between .granular drainage and floor slab. This layer also helps in minimizing shrinkage stresses as well as floor cracking as a result of a reduction in shrinkage restraint.
