This depends a bit on slope, soil type, local terrain etc. can you post a pic of the area?
Why new? Is there existing? Have you had it scoped to see where there might be an issue & if it can be fixed? Generally it should be down at & beside the footing. It should also run out to daylight or a sump pump - if not you are quite simply trapping it next to the house where it will find a way inside.
Our basements leaks really bad and the husband says it is what he thinks is wrong either the tile is plugged up or or non existing I was told that it is suppose to be about a foot from the house and 3 to 4 feet down
Well before you dig up the entire perimeter is the ground sloping away from the house (at least 1" per foot for at least 6')? Do you have gutters & is the water being dumped out at least 3+ feet away? Beyond the pics KMS mentioned of the area you may wish to include a few of the areas inside the basement water is known to come in from
The first thing you should look at - are there gutters above this area, and are they clear (and the downspouts, too)? You can start eliminating possible causes, until you find the problem. What does the area outside of your house look like, where the basement leak is occurring? What amount of space do you have to work in (such as, is this area near a property line or an easement)?
The guys above know what they're recommending. It's a major job but too much damage results if not done
for those who r helping me thank you this is the back of the house that needs to have drainage tile put in hope it helps Don't know what else it could be but the basement leak bad every time we get a real bad rain and when the snow starts to melt
Not much ground slope there at all...this complicates things. I did notice too however that the rain gutter in the first pic does not have a down spout on that end. considering the fairly long run on that side heavy rains will have a hard time clearing from single down spout. Before you start digging up the yard I would start with a gutter rework.
re-pitch the gutter from a high point in the center and add a second downspout. so you will have one on each end. ensure both of these discharge at least 4 or 5 feet from the house.
there is a down spout in the far side of the house
adding a second down spout on this side should help with overflow of the gutter itself during heavy rains.
