I bought my old house about 3 years ago and it's been plagued with water in the basement ever since I bought the house. The basement had paneling on most of the walls when I bought the house so it was hard to determine where the water was coming in at. I've had about 12 estimates from different waterproofing companies wanting to charge me anywhere from 4,000 - 12,000 dollars to install the inside perimeter drain system. I personally do not like this system because I did not want anyone to disturb the soils next to my footer. I think over time the flow of the water from the drain will erode the soil under the footer and cause foundation problems. (Funny how all these waterproofing companies also specialize in foundation work) ;)

Anyway this year I have decided to do the waterproofing myself. I have completely gutted out my basement and was going to use Sani Tred to waterproof the basement but I'm afraid that over time the water will dissolve my morter and eventually come back. I do plan on finishing my basement out after waterproofing but want something that will last.

We just had a big rain last week and I have water coming in from everywhere. Two cracks in the floor where it comes up at, around the whole basement perimeter and through the walls. I had a sump pump installed in the basement floor and the water does flow into that but still comes in the cracks of the floor.

I've read on other posts here on how to install tar and Visqueen to the outside of the basement walls but what keeps the water from coming in from the cold section and the floors? (Especially since I already have a sump pump)

If anyone has any suggestions on how to fix this please post on here. I'm open to any suggestions.

Thanks :)

Sounds like you need to have a french drain installed around the outside of your foundation, or it might be clogged and needs to be cleaned.The soil around the footers which your foundation walls rest on will not erode away.Your footers are anchored to the ground through sections of rebar, when the footers were poured.As far as your interior walls are concerned,you need to parge the walls with a product known as b-bond.B-bond comes in either 60 or 80lb. bags that you just throw in a wheelbarrow, add water and mix with a garden hoe.

There are several waterproofing options but because you are finishing your basement you might want to consider a combination of some.

You are either sitting on top of a water table or the soil around your house is very dry and soaks water up every time it rains. You can install a French Drain and that may or may not help - you could also consider attaching a sump pump incase the french drain doesn't stop all of the water. Your two largest issues however are the cracks in your basement and the pores of the concrete. First, you want to use polyurethane repair kit, one that uses high pressure and aluminum ports. Avoid hydraulic cements and injection kits with plastic ports. Next, you want to use a penetrant sealant. Do not use a concrete paint and stay away from epoxies (they will trap the water under the surface and cause the concrete to crack and spall). You can apply tar to the outside but if you take that approach you still have to repair the cracks and seal your basement walls and floor from the inside.
