 I know some tips when it comes to renovations and obviously using concrete. In most instances we use a builder or somebody of that sort. But we as homeowners also need to educate ourselves. A lot of people think they know concrete with no disrespect, but concrete you need to treat sometimes with gloves and make sure you do the right things because it can do permanent damage to whatever you do. A few tips, you know, if you do, it's all about the preparation. So if you do a floor for example or you want to do concrete driveway etc. it's all about the preparation. Meaning the ground conditions underneath where you want to cast the concrete is very important. Normally the contractor should take some of the existing soil out and then backfill or compact with a proper material from a quarry or full material or we refer it to a G5 as an example. Because the compaction of that is key to what you want to eventually achieve. I've seen too many people doing a concrete driveway a few years down the line. It's all cracks etc. And then they replace it with a pavers. Pavers are small blocks that can actually allow the ground to move below it. So it's your preparation of the ground that's key. The same applies to a floor you're casting even your foundation. It's key that the contractor actually bring in a foreign material that you don't find on your property. You pay a bit money for it but you compact it properly and that's important. So that's point number one. Your preparation, your ground conditions are very key. Then secondly I'll advise any homeowner you must look at your contractor or your builder. So listen what steel are you putting in on this driveway or floor? Normally a mesh is sufficient. The thickness of that driveway floor is also key. It will vary between 150 or 250 mm. If they go less than that raise a question mark definitely. And then on a bigger size floor I'm not going to go in too much technical detail but especially a driveway which is sometimes a long area. We call it so-called saw cuts. They need to cut in the concrete. It's an expansion joint basically to allow if there's ground conditions or that moves slightly it allows that concrete to actually also move with the ground conditions. When you do the bit more high-end extension like a suspended slab on the first floor normally that should be designed and signed off by engineer. Approved so because they design it and they should check the steel. The steel fixing before you can actually cost the concrete. Not after that. It's very important that the engineer signers off the steel that goes into the concrete. Concrete and steel combined gives you the strength. Not concrete on its own, not steel on its own. Concrete's got good compressive strength, steel got good flexural strength. The two combined you can actually do a suspended slab for quite a big area. Then on any concrete when you place the concrete the contractor should have at least some form of vibrating equipment to and we call it a poker vibrator which is well known and can hire any of these equipment higher places to actually vibrate the concrete. The reason for the vibration of concrete is a percentage of air in your concrete and you need to get that air out. If you don't get that air out it can weaken the concrete strength and the strength of the concrete. Then concrete needs to cure. There's various ways of concrete. If you've done the floor or slab and it's properly floated, the easiest way is to cover it with plastic. Sometimes people also, after the concrete is set, put some water on it. They probably tell you as a homeowner to water the slab or the foundation every day. That will help with the curing of concrete and especially will help with some surface cracking. The reason surface cracking happens normally at a homeowner is because the temperature of the concrete inside and outside is different and also because of wind and factors like that which dries the concrete out on the outside quicker than the process of chemical reaction that happens inside the concrete. So curing is important. It will give you a better lasting product. These days, in the old days they tend to leave the foundations or the slab of a house for a month. Concrete has changed, technology has changed, chemicals we add. You normally rule of thumb, you achieve 60% or higher on 7 days. So if you design a concrete for 30 MPa, if that's your foundations, you should reach 24 MPa after 7 days. And that's why people sometimes we say, but why do they start building the wall so quickly? Because you can actually achieve that higher strength in a week. So that is some of the tips I will say that home owners must be on the lookout. We don't expect them to be concrete specialists, but just are sometimes the difficult questions for the contractor or builder that is helping you with this home renovation.
