Basement waterproofing

[Jeff S]

What is the best waterproofing product I can buy to waterproof my new block foundation?

Thanks for the help,

Put in a Beaver system and have no worries for the life of your home.

Slot you talkin about the lower wall drainage system??

[harvey lee]

I would agree with the beaver system. My son and I installed it in his basement and that was the end of all the problems.

You could dig around the foundation and tile but that is rather spendy and the beaver system works well.

Sparce, What I'm talking about is what I did in the basement of our new home. I guess I always thought it was called a beaver system but maybe not according to Harvey Lee. What I'm talking about is before the cement in the basement is poured you put tile all the way around the inside of the foundation to a sump hole. Then in the very bottom of every block you drill 2 holes. Then you run tubing from the holes in the block to a hole you cut in the tile for the other end of the tubing. I also tiled all the way around the outside of the foundation also. This is very easy and would probably take the average Joe an afternoon depending on the size of the foundation. You can also do this after the cement is poured but it involves a Jack Hammer and will be a lot more costly. For what this costs before the basement is poured its just not smart to not do it. Even if where your biulding is the highest hill in the country side. I'm sure a few people in the Webster South Dakota area wished they had it done.

Slot thats what I thought! I've installed a couple but after the fact!! everything hauled out a window or up the stairs,then in reverse for the concrete!! Its a great system but other facters determine if its needed.I think hes asking for block sealer,sealer membrain,code requirement for basements to seal out moisture.personally I'd seal it with any sealer for basements then apply closed cell rigid 2" insulation designed for underground.because most basement moisture is comdensation any way.I think that code is waste of time!!!!

My son works for A company that sprays pickup beds. They also spray new basement walls on the outside before it is back filled. It works great keeps the water from coming thru the walls. A little spendy. I would have it sprayed on my basement wall instead of taring it, if I was building a new house. I had him spray the fenders and bottom of my hard side fish house and it still looks great after 4 years.

Nutty Tars is long gone I think its now considered hazardous there are lots of products for basement applications though so many its hard to recomend any and it depends on soil perk,watertable,raingutters all kinds of variables.

[rattlereel]

Tars are still around and in fact Fargo and Moorhead 2 coats of tar are required when a house is built in the flood plain. It is still an option as a DAMP PROOFER. Tar isn't a water proofer.

[rattlereel]

Jeff, a peel and stick type of water proofing is the best. Next is a liquid membrane followed distantly by damp proofering ( either clear spray or tar).

WR Meadows makes a very good product that is fairly easy to use, it is called Mellroll LM. This is a roll on type of water proofer.

When you put on any product that will be a different color than the concrete be sure to keep it as close to final grade as you can. It looks funny to see a black ring around a house below the siding. It's very hard to remove this if this happens.

Damp proof is the word. Nothing is going to hold back hydrolic pressure. My best advice is to not let the water get down there. Proper grade so the water runs away from the house.

Rattle nothin aginst you! but why do people yet build in flood plains?Kinda dumb ya know,they build cant get good flood coverage (Insurance)then it floods and they complain and want tax payers to bail them out! Its the same with those who build on the beach in hurricane prone areas!They seem to have bucks for really nice places,then it happens! and they want to be bailed out at others expensises

Sparcebag, same could be said for tornadoes, forest fires. Lets stay on topic please.
