Ok, someone screwed up. I put my sump basin in the basement floor, and
used about 7 bags of 3/4 gravel in the pit (350 lbs worth). everything
looks good. Then I realized I forgot to wrap the basin with fabric.
Obviously during my haste and rush, I overlooked this, so I have 2
1) what harm will be done without the fabric?
2) Is there a way to put fabric on the existing pit?
Sump pits without fabric over 100 years old can work fine, it depends
on your soil type. My pump and pit is 90 years old and flows fast. I
have clay, its possible if you have sand it might be an issue, maybe
contact a co that makes the pits or google the info. What you have may
not be a mistake.
When I busted up my concrete, I had dirt till about 20" down, then the
last 10" was sand. By the way I also hit water about 22" down. That
was a nice sight to see. It looked like I had a built in swimming
pool in my basement.
I could keep an eye on the silt. I guess I could just line the inside
of the basin with the fabric and put a few bricks on the bottom to
Like Mr. Ransley, I've seen ones that have been in existence for
decades with no fabric and no problems. If it won't work without
fabric, how do you explain natural springs? I've seen those along
the side of the road, where someone put a large clay crock or
similar, with no bottom, in the ground with no bottom. Water slowly
runs in and
people took the water out into bottles to take home. No silt
clogging up the works their either.
