Wood dividers for concrete patio

I have poured concrete patio and the sections of concrete are separated by wood boards, about 1" wide. The boards have rotted and weeds are now growing up through the gaps. I'd like to replace the wood, but i'm not sure if there is a recommended type of wood to use for that. Since it will almost always be damp and in contact with the soil. Should I get pressure treated? Redwood? Cedar? Something else? Thanks.

What about some Trex or similar composite (plastic) boards?

I thought about that. The home depot near me doesn't seem to carry much in the way of composite boards. I might try the lowe's or OSH a little further away. I wasn't sure how the composite would hold up to that kind of use.

You could run into a problem removing the boards.

Not real common, but some contractors will drive nails through the wood in both directions. This was done to prevent the frost from heaving the wood upward. After they were in place the concrete was poured the wood was tied to the concrete surrounding the mails.

I had a patio poured and the contractor (friend) did everything possible to do it right.

not likely, since i'm in southern california, frost isn't really a problem. The wood now is so rotted that even if there are nails, the boards could be pulled up around them and the nails removed with a dremel.

Question After repair, glue is leaching out and making board white

We did a repair on a wooden divider that had rotted out in our patio. We hired a contractor, who had a tough time fitting the board into the space. However, he did successfully complete the work. Now it has been several months, and with the recent rains, white glue has been leaching out and staining both the board (now appears white washed) and the surrounding concrete. Any ideas on how to fix this?

Wood dividers for concrete patio

A contractor glued a patio together? - Not the right thing to do, especially if it is Elmers white glue.

If the glue dissolves in water, the stains should go away with a little time.
