hi folks, as always even though it has absolutely nothing to do with welding, this is the first place i thought of for help, what a great place
So, small bit of background.
the cracks are going every which way, the two biggest by far are going across, perpendicular to the expansion joint. the rest are just spidering out. should i be worried ?
hope the pics give a good idea
So, small bit of background.
- i had a 20x30 workshop that came with a house i purchased 2 years ago.
- before i changed a ligh bulb in the house, i planned on a massive workshop extension
- so, early last year i knocked the front wall off the old workshop, pulled the roof off, and extended it to 60x30, with a 30x10 machine shop annex.
- the original 20x30 workshop has a very good 10" deep floor, and i added a 40x30 6" slab to it with 35n concrete (no steel)
- there is 1 expansion joint down the middle.
- this was poured in july last year (not by me) 6" deep, 9" pads under the steel.
- in the last 2 - 3 months, hairline cracks appeared, wheich have grown steadily to 'concerning'
- im still waiting on the guy who did it to 'call in when he gets a minute'
- what say ye?
