Well,after many loads of dirt hauled out ,I am close to putting footings in for block wall . I am only doing half a wall at a time . Everythign is supported good. Got big I beam and screw jacks . Standard 8x16 inch footing . Has anyone used "Form a drain" footing forms that are rectangle plastic , hollow in middle to use as drain tile . Also , should tile inside be tied into exterior tile and then to sump ? I need to get some pics posted of this project . Kinda overwellming ..I'm running out of digging friends ,,lol
 
Tile needs to go somewhere lower or drier than against the wall or its pointless.

I've not used the product you talked about. I've only used black tile or perforated pipe with clean crush and filter fabric.

I wouldn't load half a wall before finishing it, you could have settlement at different rates.
 
Been around several jobs here that the drains /footing forms were used and everyone seems to be pleased. Pricy but when you figure
the labor savings and the finished product
not a bad way to go.
 
We used to tie in the inner and outer drain tile, and depending on where the water needed to go, most times it went out and away from the foundation, open to daylight, a perforated concrete drywell or to a storm drain etc., there may be an applicable code that specifies in your area, but the object is to make it drain away from the building, might be specifics on how that is done outside of the building line, or do as you see fit in rural areas.

I'm curios as to how that forming system maintains slope for the pipe.
 
Form-a-drain has connectors just for that. you don't have to have slope for the tile as long as it's all level. You can also vent it for moisture and Radon gas if that's a problem in your area. As long as you have a good sump or it drains downhill from the house at a good angle and distance you should be okay. I don't have a sump in my basement, it drains about 150' away and about 10' below the level of the tile.
 
I used it when we put in my boss's house foundation about 8 years ago.

I would use it again. Foundation drain on the outside, you can sump it into gravel or tail it off into daylight if contours allow. You can get a fitting to convert to 4" plastic.

The inside was used for radon vent. I personally think radon gas is nonsense, but it has value for insurance and resale value purposes.
 
I only know the way I learned, which is 4" tile all around the outside, 4" tile all around the inside with tie ins through the footings joining the two. The inside loop then run over to a sump for pumping. I believe there is a code for this.
 
What ever method you decide to go with it isn't a bad idea to run it by your building inspector. If he does not like it( or is not familiar with it), you may save yourself some grief. Dave
 
My son used the form a drain footing forms for his ICF home in Wisconsin and he was very happy with it. The guy that he bought them from was very helpful and would have all of the installation information. Email if you would like to discuss it.
 
Here in Scott County, Ia, the inside and outside tiles are joined at one point. But, the inside tile must still go to the sump pit. Never have seen the "form a drain" footing forms used.
 
I would not tie the floor drain to the out side downspout drain. If you loose power, you've got problems. I would run under floor drains through a sump pit then out on grade to an outfall. Take the downspouts out as far as possible from the house. Be sure to draw yourself a map of where you put them. I have a whole town's system in my head.
 
No,,I would not hook up downspout to tile . I was talking tile around exterior of footing to the interior tile . I am leaning towards a sump inside , and maybe an exterior sump if I have enough fall from grade to make it work , if not , will tie them together and run one sump .
 
I used form a drain when we built our house. The inside one ties into the outside one, which drains out over the hillside behind our house via gravity.
