How do I stop water from seeping through my poured concrete foundation?

Question

I have gutters and window covers installed. Water comes into my basement near the base of the walls after a heavy rain.

Answer 1

See if you can lead the water that comes down the gutters and downspouts away from the foundation. You can get 4 or 6 inch pipe that receives this water, and sends it downhill away from the house. You may have to run a very long pipe or pipes to get to the far side.

I used to have this problem, but this technique worked great for me.

Yes, sealer will help, but if the water is pouring fast through the walls, you have a severe drainage problem, which should be solved.

Answer 2

The problem usually lies with where the water is going once it comes out of the downspouts. Most of the time diverting the water away from the foundation with some type of tubing will take care of the problem. You can go to Home Depot and buy a black corrugated pipe with an adaptor that fits over the end of the down spout. This can be buried and diverted where ever you would like or it can lay right on top of your lawn, but you have to move it to mow your lawn.

Answer 3

I had the same problem. I have a sunken basement and I would flood during heavy rains. Unfortunately, the bad news (at least for my home) was expensive. I had to have "French Drains" installed under and around most of my basement. The crew used jackhammers to dig down a few feet - they created a moat around the inside of my house, lined it with a straining type material then cemented it in. I also installed a sump pump (as long as I was digging anyway). If I didn't have the sump pump, I probably would still flood during the heavy rains. The french drain is prob. only good for light to med. moisture.

Answer 4

Install a French Drain around the outer perimeter of your foundation.
It will channel the water away safely.
You can also try installing drain lines to divert the runoff from the downspouts away from the house... much cheaper than French drain too.

Answer 5

Diverting the water is the key, but also make sure the ground around your foundation slopes away from the house. Fill in any low spots with top soil.

Answer 6

DRAIN TILE! But it can be expensive to install because it goes around the perimeter of your footings.

Answer 7

put plastic down (and up the walls) then a 3" skim of cement on floor and walls (do 1 wall at a time, floor first. use steel mesh in the gobbo)

Answer 8

I would suggest Dry Lock. or a concrete sealer. You apply is like paint...it will stop your problem..


Have a Blessed day

Answer 9

Have you used a concrete sealant? The one we used was thicker than paint and brushed on with a paint brush.
