How do i stop water from seeping thru the concrete in my basement floor?
Question:I have water that just mysteriously appears on the floor of my basement. There are no water leaks from above, just wet spots on the floor. Some are near the post but others are just in the middle of the concrete. There are no cracks near the water either.
Answers:
I would offer this simple test. Take sevearl pieces of foil about 4" square and tape to basement floor in different areas including the areas that have water when dry. Leave for 3-4 days. When you remove the foil, two things are possible. If on the concrete side you have condensation, there is moisture passing thru the floor slab. If you have moisture condensing on the open air side, you have too much humidity and this can be fixed by using a waterproofing paint on the walls if they are unfinshed. With the floor, that can effectively be fixed from the outside by making sure the gutters and downspouts and hooked up correctly, and that the actual earth(dirt) , not mulch or gravel, is sloped away from the house. A dehudifire could also be of help. Also, you might want to tract when these spots happen like before or after a rain. good luck. ref. www.ugl.com/drylok/...
I had the same problem but now the have a sealant that prevents the seepage of water trough cement.Mine came in through the side of my house and it stopped it. I would buy the best they have. You kinda paint it on. Ck with you local home store, and good luck!
I would look into seeing if that is your only problem. Do you have a sump pump system? Why is there moisture and where is it coming from?
you are sure it isn't from a clogged gutter or a leaky dehumidifier hose?
Could be just a wet basement. you can paint your floor with Seal Krete for this or run a dehumidifier an hour a day.
Water does not seep thru concrete floors. That is impossible. So application of a sealant is of no benefit.
Water is probably coming at the joint where the basement floor meets the concrete outside wall and then it runs to a low spot on the floor. It then appears to have come from that exact place, when, in fact, it came from possibly even far away.
As a last resort, take and caulk that joint where the basement floor meets the outer concrete wall. Wire brush that clean, then apply RTV clear rubber sealant from a Caulk Gun tube to that corner and smooth it in there using a glove and finger.
If you have gutter drains, take and run underground pipes and drain off those gutters at least 20 feet from the house. There is info out that basically says that downspout drains cause 90% of the wet and moisture problems in basements.
Check also and see if you have adequate number of downspouts. Too few, will cause the gutter to overflow and heavy flows of water will run down and flood out the internal drain system for the footer which connects to the sump pump.
