construction, a grade slab is a relatively flat concrete structure built on top of the soil at ground level. This simple slab design differs from the reinforced slab technique used for elevated concrete floors, and does not require support from underground footers or foundation walls. The grade ...

The minimum concrete cover requirements are based on exposure conditions and rebar size. In your case, the slab is not exposed to weather or in direct contact with ground, allowing for the3/4-inchcover, provided the rebar is No. 11 or smaller. What Is Minimum Cover? Concrete cover for re...
The grade of concrete is another aspect to understand. Some areas require sub-grade materials to be added prior to pouring the concrete, which can add to the cost. Lastly, installation aspects are worth looking into when calculating the total cost of a project start-to-finish. For example, ...
That crack appears to be between a landing, probably poured on grade, and a foundation wall probably sitting on a much-deeper footing, so you'd not be surprised that there's a crack between them; if the slab or landing isn't settling and you don't see settling or cracking in the sta...
As far as the slab work goes - what are your thought on working around/under rebar? Remove it without worry, or try to undermine it if at all possible? Oh one more thing - Im using a 7.4lb impact force Baurer Rotary Hammer. Ive also got a little pneumatic air hammer/chisel. The Ba...
design for the reinforcement rods also reduces the risk of curling and tensile stress pile-up inside the concrete volume. This acts as mid-panel reinforcement for the concrete slab panel, so instead of rebar, which cannot move in a conventional method for concrete pouring, the web designed can...
Due to the edge distance requirements of the truss rebar, the width of the remaining slab in all splitting areas should be no less than 400 mm and should be maximized for mechanical properties. In the detailing design process, engineers rely on design specifications and a priori knowledge to ...
