As those of you who read my initial post know, I'm in the process of
digging out a hole for a paver patio that is outside the walkout
basement - which happens to be the low spot of the property. To
recap, I just removed an old
slab of cement outside the walkout door and as I was digging about 10"
down a water puddle formed along the foundation and I ran in to (what
I thought was) a drainage pipe. This pipe runs parallel to the
foundation about 10" below the level of the basement floor. I
presumed the water drained from this pipe to the sump.

Can you connect this pipe to the sump? If so, now is a good time.



As it turns out the previously mentioned pipe turns out to be an old 5
foot piece of 2.5" pvc that was half under the old concrete slab at
the doorway with the other half just covered by dirt and gravel. The
pipe was sitting on gravel and was atop plastic and parallel to the
house against the foundation. It looks like it was intentionally laid
this way. The thing is the pipe does not connect to anything. It's
just 5 feet of pipe lating there. I can remove it.

Which brings me to the next problem. Why is there water pooling
against the foundation. Granted, it's below the level of the basement
floor, but I'm not sure that I can lay a patio atop it. Does this
water pooling suggest that the drain tile is not working correctly or
is this a natural type of occurence? next, can I safely put a paver
on top of it? The water doesn't seem to get any higher than a certain
level. Even if I try to fill the hole it seems to seep in the
ground. It doesn't rise. For patio purposes I suppose I could back
fill the hole with gravel, pack it - that would get me about 10", then
the subbase of the patio wouldbe another 5" with a 1" sand base and
2.5" paver stone.

I'm at a loss here.

Water would be pooling because you are deep enough in the ground vs. your
local water table. AND your weeping tile is not connected to anything.
Can you contact the builder about that? probably they need to fix that.
Builder may not even know that was done. Perhaps plumber was skimping and
neighbors have this setup as well..

And it gets even more interesting. I decided to do more digging
(literally) and I found the drain tile on one side of the walkout door
and it just ends - not covered, nothing. Reached in it to clean out
the sediment that formed. So, what I know so far is what it looks
like below:

Should drainage tiles be connected all the way around the house even
with the low point of the property being where the walkout door is
located?
