We have a screened in porch which currently has a concrete floor. We need something which is for outdoor (or outdoor/indoor) use and not that expensive.

We will be getting outdoor rugs regardless but want something for underneath them to cover the whole area of the floor.

We saw these heavy duty type of squares that are really for grass for inside a gazebo or something like that but they were pretty pricey...

any ideas would be great! tia.
