Over a year ago I had a large concrete patio (24' x 26') poured.
This concrete patio butts up against the foundation of our home.
I'm unsure if it was tied into the foundation of the house or not, but I strongly suspect it was. I wasn't around for the entire installation, only arrived home when the contractor was screeding (unsure if that's the correct term, bear with me) the slab.
I'm worried that if it is tied to the foundation, it'll crack my foundation and cause water to leak into the basement.
The home is 12 years old, proper drain tile setup.
The foundation is wrapped with the dimpled plastic for drainage.
There is no expansion joint or whatever between the foundation and patio because the contractor said the plastic wrap was good enough.
The slab has several control joints.
Slab has rebar and wire mesh in it.
The patio has a good slope away from the house, it has no puddling in heavy rain, etc.
House is built on a hill so drainage in the area overall is quite good.
I live in Vancouver area, Canada. Our average winters barely ever hit freezing.
With all that info, can anyone answer if the slab should be tied to the foundation or not? Thanks!
