Browse Forums Paving & Concreting Re: Is Exposed Aggregrate better than all other types of drivewa 21Jan 20, 2010 5:53 am there's a lot of built up frustration/anger here.... I was looking for some help on trade advice received ('cause I know carp about cement): Do I need to regularly reseal if I use exposed agg? How much does re-sealing cost per metre? Premixed colour pro's & con's Experience with DT Fauxtex as an alternative to pre-mix (an after laying colour). ie. Does it chip away/discolour/fade? Also should I insist on using spacer material on all edges which abut house walls (even if the opposing concrete edge is open/unrestricted) ? I'm thinking about an area of 90sq mt which could expand/contract a bit... Help would be greatly appreciated (otherwise I could become a bit..ing cross-dressing hairdresser who passes on information from a friends' mate's best man's dog which would be just plain wrong ) Re: Is Exposed Aggregrate better than all other types of drivewa 23Jan 20, 2010 10:10 am Reseal only if needed (ie high traffic) maybe every 3 years tops. Coloured concrete is fine if the mix is designed for the application. Colour on top is shyte IMHO, and is where we get weaker surface concrete as the colour dilutes the cement content, also water is likely used to 'help' spread the colour. The faux stuff we don't place so go ask google I am not into bagging stuff. If the grano (concrete placer) doesn't use 'spacer material' foam, then don't use the grano, because they should know what to use We seal exposed aggregate for about $7 sq mtr... less if you do it yourself Rosco & Neen Experience with DT Fauxtex as an alternative to pre-mix (an after laying colour). ie. Does it chip away/discolour/fade? DT F@UXt3X is having a good add here and I don't understand your question... Does it chip away or does concrete chip away??? Hope some of that helps Where you are coming from is where you are going to... Re: Is Exposed Aggregrate better than all other types of drivewa 24Jan 20, 2010 1:54 pm Thanks Onc. The reference to DT F@UXt3X was to gain information - the assertion from the grano was that it is a harder overall finish than concrete alone and won't fade/chip. Also, that the alternative pre-mixed colour can have the effect of weakening the overall hardness therefore implying the surface will be weaker than any alternative after-curing surface treatment (DT F@UXt3X included). Thanks for the advice on coloured concrete (fine if the mix is designed for the application). How can I determine the mix qualities? Far out! Exp. Agg requires acid wash then pressure hose? Grano said the area's not suitable because normally hose from middle to outside & he reckons not enough space as three walls are a double carport at lowest point & only one drain point (which would clog?). My concern is that without any corroborating evidence/experience, I don't know what to expect. I'm spending $10k or so (not much for some, is for me) and don't want to regret making stupid decisions because I didn't bother to ask someone who knows !!!!! Then end up with surface that is carp and cracked and make me mad Re: Is Exposed Aggregrate better than all other types of drivewa 25Jan 20, 2010 3:00 pm I have no experience in exposed. DT F@UXt3X throw on colours do increase surface durablity if applied correctly, eg, a properly coved F@UXt3X will be "harder" than plain or colour in mix of the same finish, by how much i don't know, nor would i be to concerned, as long as either are installed corectly both still need to be sealed and resealed, will wear and fade if it is not. will still chip. chips will be more apparent as will wear on a F@UXt3X surfaces Colour in mix can weaken overall concrete strength only if to much pigment is added. Can also have colour variations if mix design is not consistent between loads. Make sure your contractor is a pro. Re: Is Exposed Aggregrate better than all other types of drivewa 26Jan 20, 2010 3:51 pm If the underlayment (concrete in this case) is softer than the topping, then the risk is the harder toppings surface tension 'may' increase from thermal expansion and 'may' delaminate from the weaker substrate. It stands to reason that the adhesion ability, is very important to consider. Question is in, the 'pull off' strength/mpa strength, add to this thermal expansion co-efficients of the 2 products, or thermal equilibrium, wear n tear, surface durability, slip resistance, cost of secondary applications to a sound substrate, sealing, resealing are they going to give you a cost effective job. If the concrete is placed poorly, then I can assure you the cracks will be mirrored through whatever is coated, tiled, painted onto the surface. You have a dilemma, as we all do when seeking advice from any profession. Products and services are limited by the ability of the practitioner and other 'non-given' factors. Tell me what you are trying to acheive and I will do my best to give you the advice best suited to your needs and wants.

Re: Is Exposed Aggregrate better than all other types of drivewa 27Jan 20, 2010 6:44 pm I have exposed aggregate for my driveway, I ordered it with medium size brown river pebbles through the whole mix. I sealed it with SIKA sealer and it cops a really hard time from the power steering on our 4wd! 2 years on, and no pebbles have leapt out and the drive looks like the day it was born! It has worked out very well for us..

Re: Is Exposed Aggregrate better than all other types of drivewa 29Jan 20, 2010 7:19 pm how would you know what strength of concrete your getting let say you wanted a 25 gr or 30gr ,the grano orders the concrete .Do you ask him for a proof of receipt or do you ask the delivery truck driver receipt of the concrete mix Re: Is Exposed Aggregrate better than all other types of drivewa 30Jan 20, 2010 7:34 pm First you be coy and ask the grano what they will use, play dumb! The plant will supply what is ordered! You can check with the plant and you will pay a small amount for higher strength concrete but from 20 - 25mpa is like $6 per cubic mtr so bugger all. The strength of concrete (MPA) is related to the cement content. @ 20 mpa the strength is low, so this would be for footings, paths of no consequence, then 25 mpa most house slabs, paths such as driveways standard, 32 mpa for high performance concrete ie polished concrete heavy weight loads and commercials stuff. Then there are additives to reduce water in the mix, so less shrinkage etc, fillers to aid/reduce air entrapment, voids etc For benchtops and vanities we use a special 40mpa mix hard as the Hobbs of hell, with super plas, silica fume...

Re: Is Exposed Aggregrate better than all other types of drivewa 33Jan 20, 2010 8:08 pm THE WONDERFUL WORLD OF CONCRETE - according to Vundaful! One day, a big truck called Hanson pulled up outside a factory. Hanson was very thirsty, he had been running on empty for hours! The nice people at the factory got the big pipe connected to the hole where cementium was mined and smelted, and let Hanson take a nice long drink! Now quite refreshed, Hanson made the long trip to Vundaful's house, whereupon he vomited out everything that he had drunk into a little wooden frame. The End.
