Default Weeping tile installation

I'm thinking of having the basement excavated by a local guy with his mini-ex ($500.) I am trying to figure out the best way to do weeping tiles.

1) Weeping tiles should be under the footer. These seems to be the problem with most of the weeping tile repairs on youtube. The water will get into the footer and wicks into the rest of the foundations.

I am thinking i will need a 6" slope for every 25' side of foundation. So the weeping tile will end 1 foot bellow the foot +4" for the pipe. 16" bellow the footer he will need to excavate?

At that point it would connect to solid pipe and head to the ditch by roadway.

Also it seems some people put a layer of plastic under the weeping tile?

2) Would you install access pipe? Maybe at this point would be best and at the start and at highest point. I think a solid pipe that goes up along foundation with a t-intersection at the bottom, then connect to the filter pipe. I guess the idea is that you can sleep out the weeping tile in 10 years if it is blocked up?

3) how long will 1'x1' of gravel take to huff 100 feet around the foundation? Should i get the mini-ex guy back?

wrong:

You'll need the machine operator to come back to fill the ditch anyway. If you plan properly - and you have the guy for the day- you could get both done on the same day.

I put in a "cleanout" when i did my weeping tile. I haven't had to use it yet, but I imagine one day it may come in handy. In the meantime, it has caused no problems.

On new construction up here they use a solid pipe that comes with holes in it, load in the gravel and put some felt on top of the gravel to filter the dirt. Use "Y"s for clean outs so you can shove a hose down and it will go in the direction the water is going. Usually the guy with the hoe does this work, ask him how much. they do it so fast it will make your head spin. If you think some times you would like to drain surface water away, run a second solid pipe for that at the same time.

good point. I dropped a second pipe -this one solid - in the ditch and routed my downspout to it. It makes a long invisible run well away from my house.

I'm not sure i could watch this guy for more than a few minutes again. He makes some good points, but how can you believe a guy that needs that much editing to get through a paragraph.

Neal, you should take a look at the video. He seems to be tearing out exactly what you suggested putting in.

I can agree and disagree with a bunch of what he says. I dug up the outside to waterproof the outside of the foundation, why wouldn't he just run a new pipe outside and call it done.
As far as going below the level of the footing, he makes it sound good but the old pipe was draining water that was getting within 4" of the slab now he will be draining water a little deeper,what about the water below that.
If you are pumping out X amount of water at one level and then you dig in deeper, how much water will you be pumping then, and to what benifet.

I have argued before about the drain being on the outside should always be first choice and with real good drainage down the wall so the mud dosn't push against the wall.

I thought the same thing; if you dig a deeper trench, then the water will always be below the pipe. He also seems to dislike PVC - I'm not sure why. But i don't think he ever shows what he uses.
This guy is simply using sales technique in place of trying to educate anyone.

When we install these drains we dig the trench and then put filter fabric in first coming up both side then the rock and pipe and wrap it up like a burrito. It will keep a lot more dirt out of the rock and make for a longer lasting system.

I am still confused as to what is the purpose of weeping tile is?

Can we agree : Weeping tile plumbing system is intended for a flood situations. maybe once a year?

Otherwise people are using it as a plumbing solution for regular rain, excessive water around the foundation. Can we agree the weeping tile system as it is will not work for this problem, at least for not very long ?

I am wondering the weeping tiles system may make the problem worse, because the water will be drawn through the grave to the pipe but then without enough of a flood it will just drain...bellow the footer! Exactly were i don't want it.
But this is why you have to put a water barrier that goes under the pipe all the way up. It seems some people put plastic under the pipe and other don't? It seems the pipe should be designed with holes on the top half only.
If there is a big enough flood, it may fail again, again why would i want water ending up bellow the footer and slab?

The other solution is above the gravel could be 2'x2' of open cell foam to absorb any rain water. This would work as a filter too. I guess nobody has tried this.
