Just discuss with the brickie if there are any flashing waterproofing issues that need to be considered for the external doors. Re: Owner building in Jimboomba 22Aug 17, 2014 8:19 pm We've had a bit of rain over the last couple of days, around 70mm in the general area, and even though I had put down 100mm agi pipes with gravel surrounding them, the back of the house had water pooling around the back of the house, and even though it had dropped down from its peak, the water didn't appear to be dropping any further. So I started to dig up the agi pipes and even though I'd dug down to them with water sitting over the top of them, the water was still not getting away. Eventually I found the end of a length that was under the water but floating, so I took the end cap off and the water started to drain away. I was very surprised to see that the black agi pipe was not allowing the water to drain through it, it was almost as if the clay'ish water had blocked all the small slots in the agi pipe. This has got me very concerned that the agi pipe that I'd put in to the ground was just a waste of time, as the water will just pool up out the back of the house.

Re: Owner building in Jimboomba 23Aug 18, 2014 11:07 am Brendon, the black bendy agi pipe is next to useless in my opinion especially where falls are critical.. We almost always used to use the 90mm slotted ag pipe like the one shown here. Sometimes we would up that to the bigger 150mm pipe. http://www.iplex.com.au/iplex.php?page= ... =13&sec=86 We also used a nylon sock over it which keeps out sand but allows the water to penetrate to the pipe and drain away. It is a lot stronger and more rigid. Where possible we would place 100mm or more of 20mm gravel on either side and over this as well. Stewie Re: Owner building in Jimboomba 24Aug 18, 2014 1:35 pm Thanks Stewie, it is the black bendy agi pipe with the nylon sock over it, which I thought it should be the right thing to put down, but sadly it appears it was a waste of time. I did put gravel below and all around it too, but that didn't do much by the sounds of it. I'm thinking I might have to use that 90mm slotted pvc pipe, and just dig it above the existing black poly agi pipe. I'd dug the agi pipe in around 300 - 400mm below the ground, but now that the waffle pod slab is that much higher than the ground, I think I'll still have it sufficiently under the ground to work if I put it in. Where do you get that nylon sock from for the 90mm slotted pvc piping ? Just going to be a hell of a lot harder to do now that the house is there. Owner Building at Jimboomba Woods in Logan City Qld.

Yeah, I was worrying you might say that I need it down the bottom of the trench. Looks like I'll have to hire that excavator again, as it's really the only thing that will get around the back of the house now. Just have to deal with the covenant wankers at the moment.

Re: Owner building in Jimboomba 28Aug 19, 2014 10:47 am Damn, it sounds like you have done everything right but it is the clay soil that is letting you down. Perhaps the best option would be to have some kind of a trench that goes around the side of the house and down the hill to provide an outlet for the water to escape, perhaps into a longer gravel filled trench or perhaps into a 'pond' area that would only fill up when it rains, to give it time to slowly soak away. Since you are right up the back of the block it should give you some room to play with (neighbours permitting lol!). If you have a little trench/stream that wiggles back and forth then it would slow the water down and perhaps also look attractive as a landscaping feature? I guess if you were really desperate you could install a holding tank underground which would catch the water when it rains and then slowly drain it away through a gravel trench, but that would probably be overkill I was just helping my mum dig up her 30 year old greywater trench which had no drain matting over the slotted pipe and dirt all through the gravel, so of course the pipe was blocked with dirt and roots. It was good because it showed me what NOT to do as I am about to install my own! Re: Owner building in Jimboomba 29Aug 19, 2014 11:33 am I am now considering the option of leaving the black agi pipe in the ground, but adding slotted pvc pipes in different areas that I can direct via T pieces in to the black agi pipe that is just like the day I bought it internally. As the ground around the back of the house has to be raised by more than 300mm, I should be able to angle the slotted pvc towards the already buried black agi, stick some T pieces in, and some adapters, and my problem should be solved. A lot more time and effort, as well as money that I really didn't want to spend, and it should work fine. Any other suggestions more than welcome !

Owner building in Jimboomba 30Aug 19, 2014 11:58 am You could improve the surface drainage by putting down quarry rubble around the house and grading this to allow surface water to escape quickly. I did this for my build (I built on cut & fill) and it works. However the quarry rubble did cost a lot. The bonus is a have a clean, dry mud free build site. Above the cut, I also got the dozer doing the site levelling to make a small diagonal cut across the site to divert surface water coming down the hill around the build site. Re: Owner building in Jimboomba 31Aug 19, 2014 12:02 pm I think I'm a little bit too late for a lot of that. My target is to build up the earth closer to the slab itself, and have it slope away from the house, and to help it get rid of the water, agi pipes closer to the surface to take any of that water down the hill well away from the house.

Was the site cut sloped? Cut sloped ? House pad was cut flat, and I put black poly agi around the back then along the sides below the front. This black poly with sock on it has blocked up with I'm guessing the clay in the ground sealing the sock and even the slots in the black poly that I used that doesn't have sock on it. Here's a picture of the front of the block looking up to the house. :- http://www.oih.com.au/images/tower1.png The white thing sticking high up behind the house was a pvc pipe representing the overall height that my AR tower was going to be there. The back of the house is :- http://www.oih.com.au/images/tower2.png As you might see that's on the high side of the hill, where the water runs down to the house pad level, and where the agi pipes were laid, about half way between the alfresco and the bottom of the batters, then the agi pipes stretch around both sides of the house and down the hill past the house.

Re: Owner building in Jimboomba 34Sep 14, 2014 8:36 pm For those interested in my Amateur Radio tower, the first photo in the previous post shows the location of where it was going to go at close to the same height it was going to be as shown with the 100mm pvc pipe. Now if you could imagine if the thickness of that pipe times 4, which gives the actual width of the tower, from bottom to top. Not really an eyesore, particulary as I'll be adding trees and shrubbery throughout the front of the block up towards the house, so plenty of things to block the view of it from the road and nearby houses (all but the two on each side of us). Here's a picture from the front of our old home, when the tower was 15m in height. :- http://www.oih.com.au/images/tower-buccan.jpg Yes, you can see it, but it does have low'ish visual impact.

Re: Owner building in Jimboomba 35Sep 17, 2014 11:30 pm Finally got all my doors delivered on Monday, and have got my chippies lined up to install all the exterior doors. So pleased to have them finally delivered to the site. Got home today to find a email from my brickie advising that the builder he works for has now got him tied up until Christmas, and won't have any time to do my new home, so has advised me that he has to turn down my job. I really would like to keep him to do it, as he seems to take a lot of pride in his work, and I don't think I'll be able to get a new one in now, as it appears good brickies will be hard to find or a lot more expensive to get in.

I'm sure there would be a lot of other stuff you or tradies could do on your house in the mean time. There's not a lot to be done until the bricks go up. I'm not game to get the gyprocking done until after, as knowing my luck I will get 5 solid days of horizontal rain !!! Have just had the plumbing rough-in done yesterday, with council inspection booked for Tuesday. The doors arrived on Monday, with the chippies putting in the external ones tomorrow if they get time. Not sure if it is the right thing to put the internal doors in until after the gyprocking has been done. Externally there's 21 pallets of bricks right where I need to build up with fill. I don't fancy moving them around just yet. All that's pretty much left to do is manual digging work for me around the back of the house to ensure that there's plenty of drainage when we get rain here, so it doesn't sit around and soak under the slab... oh and run some more electrical in to the house... so far around 1400m of twin and earth, and another couple of hundred metres of cat6 and rg6. Oh, and all the bits and bobs of landscaping around the place. Owner Building at Jimboomba Woods in Logan City Qld.
