Any concrete experts in here? Or contractors that are familiar enough with concrete?

[QUOTE="thebestofindica, post: 14445603, member: 36210"] That is definitely not a mix-design issue. It appears to be a terrible cure/seal job. They obviously know what they did. They will respond or not get paid. As for the "beams" under the concrete, are they actually steel beams? This could actually induce differential settlement and create cracking issues, rather than reduce it as I'm sure was intended. Concrete slabs on grade rarely fail due to shear from thickness issues. Almost all cracking/failures are due to sub grade issues. By placing steel beams in the slab, you are actually sending concentrated loads into the soil, rather than letting the area of the slab distribute the load evenly over the subgrade/sub base. I'm a registered professional engineer. If you have any other questions, feel free to ask. [/QUOTE]
