35 year old house has a basement with relatively minor seepage problems that
I would like to stop. Generally just get a small amount of water running from
walls to floor drain after a heavy rain but have had, on perhaps 3-4
occasions over the past 10 years, up to several inches when the sump pump
just couldn't keep up. Inside walls have had a water proofing material
applied (almost like a mixture of cement and paint) but last prolonged
period of heavy rain caused some of that to start popping off. Options I have
seen are trenching out around the basement and applying a sealer to outside,
injecting a clay type material into the ground around the basement to seal
it off, drilling holes in the bottom row of concrete blocks inside the
basement and using short sections of hose to connect to a header and then
the sump, etc. I would like to see if there's a consensus on the most cost
effective (emphasis on effective) method that has actually worked for people
to the advertising B.S. that I generally find on-line. I would also like to
know which methods generally wind up being a waste of time and money. Will
probably be selling in 5-10 years. Grading appears to be good, sloping away
from house, and gutters have also been directed away from house.
