Re: Is this normal for concrete driveway and footpath? 9Oct 15, 2014 10:16 pm Dr House Also some tips for people who are having their drivway done: 1. make sure the mix is not too wet. Most concreaters, particularly those who lay paths, drives etc have a mix that is much too wet as that works easier for them and is easier to finish. not true, most concretors want it as dry as they can. Exposed is generally poured at 80 slump and plain grey 80-100 depending on the weather. The last thing they want is to be sitting around for hours waiting to wash it off or to broom finish 2. Make sure the finished job is cured correctly. Keep it as wet as possible once it has taken its first set, especially for the first seven days. Cement needs water to cure evenly as it goes through chemical process of curing and constant moisture is critical in the curing process. DO NOT lay it in hot weather. agree with you re the curing, but not laying in hot weather? That one sounds like it's straight out of the concreting for dummies hand book 3. Use a decent F72 reinforcement mesh (reo), and make sure you (or the concreter) use bar chairs (saddles). Do not allow the concreters to just lay the reo down and then lift it by hand as they go. Use saddles to keep the reo at the correct height will minimise surface cracks. Lifting it by hand will still allow the reo to sag in places leaving to much concrete above the reo which will make it weaker. hooking the mesh can and is an accepted method when pouring paths and driveways, the cost of the chairs doesn't come into it, there really cheap, pour enough paths and driveways and you will soon understand why there not used. 4. There is a product that consists of small strands (can be wire or various other fibers depending on the brand) that is added to the mix and will act as reinforcement to the top layer and help prevent the hair line shrinkage cracks. the product you refer to, fibre Crete is used with out steel, not very cost affective if you put steel in it as well, 5. Site preparation is imperative for a good concrete finish. The most important thing to follow is plastic under your concrete. Laying concrete over bare earth or sand will suck the moisture out of it to fast and lead to cracking. As mentioned keep the surface wet for at least a week will stop most surface cracks because it dries to fast and you get shrinkage which leads to hair line cracks. a driveway poured with plastic under it? That's obviously out of the same handbook as above. Re: Is this normal for concrete driveway and footpath? 10Oct 16, 2014 8:38 am Not using chairs is definitely an accepted method. Thats the problem. To many paths fail and they dont need to and then need to be replace. Do it properly do it once!! Re: Is this normal for concrete driveway and footpath? 11Oct 16, 2014 11:32 am Why can't they just use chairs instead of hook-and-pull-up?? Its not like a few minutes to make sure the mesh sits on the chair properly (and you don't need to use that many) is too much to ask, and the cost of chair is less than 25c per one! "Occam's Razor. The simplest explanation is almost always somebody screwed up." Re: Is this normal for concrete driveway and footpath? 12Oct 24, 2014 9:22 am Dr House Also some tips for people who are having their drivway done: 1. make sure the mix is not too wet.

True, but mixes need to be wetter the warmer it is. Dr House 2. Make sure the finished job is cured correctly. Keep it as wet as possible once it has taken its first set, especially for the first seven days. Cement needs water to cure evenly as it goes through chemical process of curing and constant moisture is critical in the curing process. Kind of False. The theory is nice but its kind of impossible to constantly keep the top of the slab wet. Cover it if you are worried, thats all thats need to make it dry out evenly. I dont believe casual watering with improve the finish to any extent. Once the top is white and dried out, thats it. Dr House DO NOT lay it in hot weather. Not exactly right, It can be done. Concreting does not stop in summer. Granted though, you have less time to work it, so only the experienced should do it. Cool months are the best time to concrete Dr House 5. The most important thing to follow is plastic under your concrete. Laying concrete over bare earth or sand will suck the moisture out of it to fast and lead to cracking. As mentioned keep the surface wet for at least a week will stop most surface cracks because it dries to fast and you get shrinkage which leads to hair line cracks. Hairline cracking will occur on any smooth finish. And cracking generally is a function of how well the reo is placed toward the top surface of the slab, how well it is overlapped, and whether the soil is reactive and whether you have taken appropriate measures for that , ie sand barrier. What I am saying overall is there is a lot more to it than your casual observations. Re: Is this normal for concrete driveway and footpath? 13Oct 24, 2014 9:36 am mgilla a driveway poured with plastic under it? That's obviously out of the same handbook as above. I think what mgilla means is, that you are confusing engineer specified structural-strength concrete with non structural. Houses and the like must have the curing process rigidly adhered to to maximise strength, but with driveways and the like the requirement is not there, I believe most concretors just wet the substrate and lay the mix straight down. Re: Is this normal for concrete driveway and footpath? 14Oct 24, 2014 7:19 pm A little but not too much OT ! Just occurred to me whilst thinking back on the last two concrete jobs, the truck drivers only took cash with no facility for CC payts and carried no change. Was same big name Co. both times, one big job $6000 ( 2 yrs ago) and one about $504.25 (8 mths ago). Didn't carry change 2nd time around so I gave him the $4.25 in 20c pcs. Is this standard procedure ? because I certainly found it a pain in the...and will be making enquiries in advance for our next job. Re: Is this normal for concrete driveway and footpath? 15Oct 24, 2014 7:24 pm That's probably because the truck drivers are regulary delivering to account customers, and no one thinks about the 'one-off' customers who have to pay cash. Next time make enquiries about paying at order time via your credit card if you wish, or visit your closest 'hole in the wall' to get the cash out.

Is this standard procedure ? It is not standard, they are tax evading. Tow truck operators will run this rort day and night too. All businesses should have C/C facilities, or accept personal cheques if they are delivering services to your property. Those that claim they do not are conning you. Ive always paid my concrete driver with personal cheques. Re: Is this normal for concrete driveway and footpath? 17Oct 28, 2014 10:26 am qebtel It is not standard, they are tax evading. Tow truck operators will run this rort day and night too. All businesses should have C/C facilities, or accept personal cheques if they are delivering services to your property. Those that claim they do not are conning you. Ive always paid my concrete driver with personal cheques. I think that's a rather broad/rash statement. Cheques have almost gone the way of the dodo, and the concrete trucks that delivered all the concrete for my slab told me they do not have eftpos facilities on-board, as nearly all their work was done on accounts. Why would any concrete trucking business provide all trucks with eftpos facilities, when it is such a tiny part of their business ?? Of course as a one-off delivery, I'm sure you could pay when it was ordered via credit card over the phone to the depot, or you get the correct change to hand over to the driver when he delivers it. Oh, and my slab was done by a concretor, and the concrete delivered was paid through his account, and I paid the concretor the total. Owner Building at Jimboomba Woods in Logan City Qld.

Re: Is this normal for concrete driveway and footpath? 18Oct 29, 2014 10:16 am bpratt Cheques have almost gone the way of the dodo Sorry, you're out of touch bpratt Why would any concrete trucking business provide all trucks with eftpos facilities, when it is such a tiny part of their business ?? Because it's not a tiny part though. Lots of private individual get loads delivered. They have to take payment somehow. They ALL deliver loads as small as 2m³, so they want the business. bpratt Of course as a one-off delivery, I'm sure you could pay when it was ordered via credit card over the phone to the depot, or you get the correct change to hand over to the driver when he delivers it. Only a fool would pre pay. Never once have I been asked for pre payment, not that they would get it. Companies prefer their drivers to handle payments in a form other than cash, hence cheques or eftpos it is. bpratt Oh, and my slab was done by a concretor, and the concrete delivered was paid through his account, and I paid the concretor the total. Thats nice Brendan, and its obvious thats the basis of why you think things are run the way you do. By contrast, most of my slabs have been done on my own. Sometimes I use a contractor to finish it, in which case I ask them to ordered the load s I can get "mates rates" through his account, but I pay the account on delivery. Best of both worlds. bpratt That's probably because the truck drivers are regulary delivering to account customers, and no one thinks about the 'one-off' customers who have to pay cash. That would be a dumb way to run a business. you shore up your payment strategy so that you can take payment from both regulars and one offs. Getting back to JJs comment though, just ask what payment they take other than cash when you order. IF they insist on cash, give them a bank cheque, or money order. Thay will pay tax on that. Re: Is this normal for concrete driveway and footpath? 19Nov 01, 2014 8:29 pm I,Ve run my own business now for 15 years,and most if not all companies still get mostly paid by cheque, I send 40- 60 cheques monthly,it's the best way due to written documentation,3-5 days depending on postage to cancel or correct an error,and you have an instant outgoing of funds report available all the time,but cheques don't get used by the public has much these days,has cards for an individual better suited to their needs. Re: Is this normal for concrete driveway and footpath? 20Nov 02, 2014 6:41 am I was very surprised that a Coy like Boral would not have the resources for a cc payment on board, either manual or electronic. My local plumber does. I was told on both occasions that "the drivers prefer cash" by the person I engaged to do the work, so I toddled down to the bank and cashed a chq for the big job and raided the Mrs' wallet for the little job. It is the first and second time I have ever had any experience with concrete being delivered by truck so was not well versed in what the standards/procedures were. I know now.
