Very very poor workmanship. A basic cement slab for a 3x3 garden shed ended up 80mm out of square and 20mm under size. Asked to fix the issue and advised I wouldn't pay until fixed. Abusive phone call followed, saying he would bring the bobcat in and turn the slab upside down. Report has been made to QBBC, but please save yourself the hassle and do not contact this company for work. I'm now out of pocket having to have the slab fixed up.
