  2. Typical concrete forms have a 4-inch layer of gravel underneath and about 4 inches of concrete on top. To build a landing for deck stairs, most building codes require the pad to extend beyond the steps about 36 inches, behind the steps about 12 inches and on the sides of the steps about 6 inches
  3. to flexure when slabs are continu-ous for two or more spans. We l d e d w i r e fabric is usually re c o m m e n d e d for tempera t u r e and shrinkage re-i n f o rc e m e n t .

Lightweight concrete composite slabs are inherently more efficient than normal-weight composite slabs with nearly identical structural characteristics and design strengths. Concrete slab-on-metal deck thicknesses are typically controlled by fire-rating requirements as opposed to strength requirements construction stage and as positive reinforcement for the slab under service conditions. Steel decks for composite deck-reinforced floor construc­ tion are commercially available in a variety of shapes and sizes. They normally consist of cold-formed corrugated sheets or ribbed panels to provide adequate strength during the con­ struction stage The most common causes of pool deck movement and other issues: Poor Pool Construction: When the pool is constructed, the backfill material may not be properly compacted. As a result, the soil settles and creates voids under the pool deck. Heavy Concrete Slab: Heavy concrete slab around the pool can cause loose soil to compress under the slab.

Excavate the slab area to a depth of about 7 inches, allowing 3 inches for a gravel base and 4 inches for concrete. Step 2 Check the forms for level (¼ inch for every 12 feet is sufficient to allow for rain run-off) However, heat is transferred directly into the concrete due to the deck plate rib and Y-shape flange, and the internal temperature of the slab rises compared to the general RC slab. As a result, the water vapor pressure is greater than the internal stress of the concrete, causing spalling [ 4 , 5 ] Where an interior concrete slab-on-grade is provided and is in contact with the interior surface of the foundation wall, measurement of the unbalanced backfill height from the exterior finish ground level to the top of the interior concrete slab is permitted. d.
