Foundation Hairline crack repair
After a lot of reading I gather there are two main ways of repairing small hairline cracks in basement foundation from inside.
Both done by injection but using different materials.
- One uses polyurethane injection
- The other one uses epoxy injection
My crack is dry with no water leaking and it is very very small width wise. It is vertical, from the floor to the top of foundation and it can be seen from the outside in the above ground portion of the wall. Foundation is pored concrete.
The builder has sent someone 5 years ago to repair similar crack at a different are of the wall and so far so good, never had any issues with it since been repaired. I 'think" they've used epoxy injection at that time but am not 100% sure.
I was looking at this company's product for DIY application:

And they have both types.
Which one should I use: epoxy or polyurethane?
I like the idea epoxy makes the two sides of the crack bond together stronger then original concrete itself.
Not sure about the polyurethane use in my particular application as the crack is so very narrow and it is dry.
Would appreciate your input an advice.
Thanks.
