My house is 18yrs old and I have a vertical hairline crack in the basement. It seeps in water when it is pouring outside during storms otherwise it is ok. I want to repair this crack and was researching online. I am confused which option is best:
- There is a kit that put the plugs ever six or so inches over the crack and then you inject polyurethane foam. (like this one https://www.radonseal.com/product/301.html). This is more tedious process, and cost little bit more.
- Second option to use a caulking gun with a product like this: https://www.homedepot.com/p/Sikaflex-10-1-oz-Crack-Flex-Concrete-Sealant-7116110/300934565#overlay It is fast and cheap.
I am not sure which option is best and give good result without spending too much of money. Please help. Thank you.
