I need a quick solution to fill a 2" gap between concrete curb that will handle the weather. It can be temporary as long as it works to block water intrusion.
Background: I'm the last house on the decline of a hill before going down into a valley. The city's storm drain is directly in front of my house. There's a 2" gap between the storm drain concrete and the curb.
My house has a basement and the last rain created a tunnel from this 2" gap to my basement. I doubt the city will be out in time for my request since there's another rain in a few days.
I've been considering foam type application, but unsure if it'll handle the pressure when the drain tends to back up a little and uncertain which foam to use for an outdoor application.
Editing for my solution: I ended up filling the inner cavity with backer rod crammed in there. Then went over it with hydraulic cement about 4" deep. Due to upcoming weather and cure time of the cement (7 days could be longer with 4" deep) I'll also put sandbags. Hopefully this will hold until city returns. Might arguably be overkill.
Could potentially use weather proof expansion foam instead of backer rod then cement or just fully use cement, but this was a temporary quick and dirty solution.
