After having a person I called to fix a floor crack try to sell me a
internal foundation drainage system and saying the crack was from
hydrostatic pressure. Then callin in a plumber that found 4 of the 6
foundation drainage cleanouts had sand in them. Then calling a plumber
to snake out the drains, to no avail. then vacuuming out the sand I
could see and snaking the drains again myself. Then pouring food
coloring into the drain to discover they actually flow freely. Then
calling in the plumber to use a pipe camera, I have finally the answer
to my basement condition.
Four of the six pipes were laid incorrectly with an uphill slope. This
means these 4 pipes are holding water and sand. This means these 4
sections of the basement have a water level elevated by 3.5". This is
why the cement we put down has a moisture line at the seam.
I was told the plumber could fix it at $95 per foot. Thats a lotta
dollars for a 2.5 year old house I have owned for 1.5 years.
Im going to talk to the builder about this. Its under warranty but I
really dont want a big legal fight. I would be happy if 2 of the 4 were
fixed though they should really fix them all...
I really dont have hydrostatic pressure buildup since the pipes do
drain, they just have elevated water level, AND probably the sand is
from erosion due to the weeping tiles being full of water due to the
uphull grade of the drain pipes under the foundation. So even if I had
a small amount of drainage, the tiles wouldn't drain until they were
full which they are. Plus I will have to keep vacuuming the sand out
since it will be 'trapped' by the uphill slope. Plus my basement floor
has a moisture line where we cut the cement.
Any tips on the extend of having the tile drain pipes going uphill once
inside the house? How much harm is this going to do? Any other advise?
