Leak from landscape drain under concrete patio
Roots have entered my 3″ drain plastic poly pipe underneath my concrete (viewed with a remote camera in the pipe), creating a leak, and have damp concrete in the area when water is flowed through the pipe ( the area has been damp for months).. There is no possibilty of any other reason for the damp concrete. The water flowed thru the pipe is only water captured in the area drains and is not sewage liquid.
Other than cutting the concrete and replacing the drain pipe, is there any product or repair I can do while the drain line is in place under my concrete patio???
The colored concrete patio was poured 7 years ago and I dread the fact if I have to replace the area of the patio it will not match the rest of the patio. The area of the damp concrete is approx 1/10th of the total area of concrete. Looking for any help with interior coating, epoxy fill, or???????
Thanks in advance.

If the pipe is kept clear of roots and other obstructions and there is no other cause for water being "bottled up" in the pipe (ie, it can drain clear), then cracks in the pipe should not cause the concrete above to be damp.
There are technologies, basically employing a fabric "sock" coated in epoxy, which will line an existing pipe with a waterproof liner. These require specialized installers, of course.

What kind of "poly" is the pipe?
In my opinion if you didn't specify the use of at least sched 30, non perforated drain pipe with positive slope, then there is every possiblity that this is your own fault.
You can try snaking out the pipe and cutting the roots to clear the blockage, but you risk damaging the pipe if it's anything other than the above. You may have to do this every other year. Probably cheaper than replacing the slab though.
