I've come across another leak in my foundation right at the point
where the septic system PVC waste pipe exits the foundation.
Fortunately it is only about 2 feet below grade on the exterior and
I've decided this is where I'll do the repair.
Water seepage only occurs during a VERY heavy rain. But every time it
happens the insulation gets soaked in the interior of the basement.
When I removed the insulation from this spot, it appears the builder
used some kind of cement to patch both interior and exterior surfaces
around the pipe.
Is there one de facto standard as far as sealing all pipe openings in
I don't understand why the builder didn'tt use some type of plastic
roofing mastic/cement to seal this damn thing better. It looks very
half-ass to me. You would think there would be some kind of plumbing
code governing this type of thing.
BTW, can someone please explain the difference between portland cement
and masony cement. Also , what does it mean when portland cement is
classified as Type I and/or Type II?
