We have a hillside house build in 1972 that did not have any protection
againsst water except for the soil pushed up against it. We live in
Oregon... WET WET.. and springs that pop to the surface all the time..like
little perking fountains.
I have been battling a breathing problem and our bedroom is in the
basement, the other day discovered the whole corner of the room WET, with
mold and mildew ..
My husband is outside in the cold and rain digging out the outter dirt
around from the side foundation. we have discovered cracks in the side
walls, and want to fix it the right way. But not sure on older foundations
what is the best procedure.. We need to get this done fast! To fill the
cracks.. what is the best product to use.
To seal the concrete what should we use..a paint on or use a adhesive to a
plastic type barrier? with pea gravel to drain the water properly...
Like I said.. he is outside right now, asking me to find what he needs to
do next... Please HELP!

Exterior Foundation Waterproofing Systems
The following companies make exterior foundation waterproofing compounds. Some are modified asphalts (Tuff n Dry) and some are rubber (Rubber Polymer Corporation.) I recommend that you call as many as possible and get product literature. Then discuss the systems with your builder. See what products he/she has had the best success with. Good luck on your project!

I am experiencing brief flooding exposure from rising storm water. I cannot
divert the water which rises to one foot in depth completly surrounding my
home and is gone in less than one hour. My home is brick veneer on concrete
slab (20 year old home). How can I water proof my exterior up to say two
feet high?
Urgently need help! Rob

We have a deck house built in 1989. There is an exterior drainage system
that helps control the water, with a solid PVC pipe leading to public
drainage. However, it seems the pipe is clogged, so we have a very wet
basement. A contractor suggested to install an interior drainage system
with two pumps, which costs more than $8,000. I was wondering if it is more
cost-effective to unclog the exterior pipes and if unclogging the pipe
would solve the wet basement problem. Thanks.

we had someone install drain tile around our foundation it seems like he
did it right except for when he ran the drain tile into the house he has it
going into a barrel with no pump or anything to get the water out of the
barrel does this sound right

We have a 10 ft long by 3 ft wide planter box surrounded by railroad ties
abutting our foundation and lining a brick paver patio. The railroad ties
surround 3 sides of the box with soil against the foundation. Recently we
have been getting water in our basement from this area of the foundation.
There was a PVC pipe that our roof downspout drained into in side the
planter box that lead out to a drywell under the paver patio that I have
since capped. I diverted the downspout to drain outside of the planter
box. There is a window well in this planter box as well that I have
covered with a piece of plywood. The window well has drainage stone in it
at a level 4-6 inches below the concrete foundation of the window.
However, during hard, driving rain we still get water seepage into the
basement. I would rather not rely on the drywell as it could have been in
place for 30-40 years or more. Can you make any further drainage
suggestions? Thank you.

Have had water seeping into crawl space for years. Have just dug down to
footing with idea of installing french drain. Suggestion has been made to
pur additional concrete on the footing to seal off the space where seepage
is ocurring at the point where footing and block join. Worried about
additional weight on footing. Your ideas? Please hurry!!

We are having a good deal of seepage into our basement. The house is two
years old and I would like to get the problem fixed. We have had a few
companies come out to look at the problem; most have had the same thing to
say. They all want to install an inside drain system. The house is on a
good slope and run off should have somewhere to go, if directed. Because
of that I think the best fix would be outside the house, a new or repaired
drain tile. I have a few questions:
1. Am I way off should I just get the inside fix? 2. What is the best kind of pipe to use for the drain tile; I have read 4” PVC and 4” corrugated, what is better? 3. How much is too much gravel fill, is more better? 4. How wide does the trench around the house need to be dug? Thanks for the help. Tom View all comments |
