    It is a shame that no one has replied in almost a fortnight... In my area there are firms that take any dunderhead off the street teach them 'three lifts, twenty five strokes, 10 to 15 slaps' and you are qualified concrete tech level "A". When they discover that they can get a 25%...

    I'm a mechanical engineer building

    More than likely the crazy cracks or alligator cracking are a result of shrinkage at the surface which could be due to any number of causes. bottom line: they NOT an indicator of structural failure! More than likely they are a result of the finishers 'blessing' the slab with excess water.

    tips for site-plumbing up with laser plumb ups

    Try the olde mason's trick. Get the heaviest bob you can find and suspend it so it and about a foot of its string is submerged in water. A 5 gal (20 L) bucket should do just fine! The friction of the water will hold the bob and its line steady in all but the most windy day. The trick is to...

    spalling of concrete cracks
