Browse Forums General Discussion 1 Jan 20, 2022 11:11 am I just had a concrete pour done, yesterday. Today I went out to take a look at it, as he said I could walk on it in socks. I am not happy with the finish. It was meant to be smooth finish, as it is to be used as a basketball court area and also as a entertaining area. There are holes in the top, unfinished edges and what appears to be non-smooth texture on top in places. We were quoted 7k for the job, we are yet to pay a cent, and given the current look of it I am not keen to pay any. Any recommendations – are these issues fixable? https://imagizer.imageshack.com/img924/3342/Gjhe2g.jpg https://imagizer.imageshack.com/img922/1221/Ikbj56.jpg https://imagizer.imageshack.com/img922/9335/pekNDq.jpg https://imagizer.imageshack.com/img924/8603/iqjB3T.jpg https://imagizer.imageshack.com/img923/7706/ai5ivf.jpg https://imagizer.imageshack.com/img923/7599/LcCcGD.jpg https://imagizer.imageshack.com/img924/7990/bgWGaH.jpg https://imagizer.imageshack.com/img923/7948/5rwzBD.jpg https://imagizer.imageshack.com/img922/7346/oG7omH.jpg Re: Bad Concrete Pour 2Jan 21, 2022 12:06 pm Hey rere Welcome to the forum I would say they are amateurs and unfortunately that's not what you want for the concreting trades. Looks like the concrete went off too quick before they started finishing/ floating. Bad luck be careful about not paying them , they are likely to drive a truck over the slab....then the poor finishing's are further compounded with cracking.

Here's an article explaining how that works. It would cost another $1,500 or so. If your concretors are reasonable, they should be able to pay for a portion of that.

Some of the images look like they may have applied water to slow the process, (water droplets seem to have dried on the finish). Probably a windy day. You can't just not pay them. You should contact them, advise them that the finish is unacceptable and appears to be outside Standards and Tolerence Guide. That you would like them to advise how they intend to rectify the works (specifically How, with what product and what will be finish be like?) until the work is made acceptable you will be withholding payment. Keep it civil, put it in writing, emails with delivery & read receipts. That if they fail to address the problem you will make an application to TasCAT. Just be aware you are required to provide them an opportunity to rectify their job. "1.02 Finish to external concrete paving Concrete paving finish is defective if it is not consistent in colour, texture and general appearance. Minor variations in finish may occur and may not be considered to be defective." (link Guide to Standards and Tolerances 2017 (cbos.tas.gov.au)). Good luck PS take a lot of photo's of the whole finished surface, date & time stamp your photos, the holes/pox-marks on the slab use a builders ruler next to them to provide a scale in the image We are Expert Consultant's, and we are here to help. Re: Bad Concrete Pour 5Jan 21, 2022 10:43 pm How to plan a good concrete pour and avoid a bad one 1.Make sure you and the trades have the full engineering details and specifications beforehand 2.Have the compaction, WPM, formwork, penetrations and reinforcement properly inspected and certified the day before 3.Check the time, weather, team size, concrete batching plant location and concrete delivery times for the next day’s pour 4.Turn up early the next day, do a quick re-check of everything, Levels, Pegs, wet area step-downs, penetrations, make sure there are enough hands-on deck, Spare equipment, safety equipment, because once the pump and truck arrive there’s no stopping, toilet break, smoko, or running down to the hardware shop… time and performance is of the essence. 5. Check the concrete batch mix, slump and get a copy of the paperwork 6. Team size 3-4+ ie Moving, Raking, Screeding, vibrating, + pump guys, floating 7. Follow the engineers’ notes/instructions for joints, curing, stripping formwork, slab loading, etc A house slab is a full day’s work, Initial set is within the first hour, better to organise and pay for extra men/day ($300+) Than to pull up the slab and lose $30K worse case. You can plan and rehearse as much as you like, but I recommend at least one experienced, qualified expert is there on the day of the pour. And if 2 amateurs rock up and things start going wrong within the first hour and there’s no one to assist …your concrete pour will be compromised.
