DIY Concrete Expansion Joint for basement floors & more with Plymouth Foam Expansion Joint

[@passion830217]

Hello, did you have the middle sections cut instead of using the expansion joint foam? Can we use the expansion joint foam in the middle instead of cutting the cross (+)? Thanks!

Those are for [crack] control joints. You don't need another expansion joint unless doing at least 20'+ wide sections.

I live in Ontario, Canada. Can i use this for outside the house on a patio slab connected to my house?

[@marinahuber5753]

Wouldn't you want the slab cement to bind to the wall cement? We have a serious water problem in our basement from a high water table. The water seeps in all along the perimeter of the basement slab.

That sounds more like a drainage issue. Might want to talk to someone about getting the water away from the foundation, rather than trying to keep it on the other side of a permeable surface. :-)

Thank you I plan on doing this to my foundation when my patio is poured. Do you think this material will handle water?

Yes It is weather resistant .

You left out how to level the concrete without a screed board. Seems like it would be hard to get it level.

How I poured the basement floor is in this video. kzbin.info/www/bejne/jKfQaalogL18fdE

Great video. Thanks

I don't think that siliconized acrylic sealant is rated for use on green (uncured) concrete.

What about for drywall?
