So I have a driveway that is made of concrete sections that mates up to the edge of my house which is brick with a cinder block basement wall. The prior owner sealed the gap between the two with cheap sealer which is starting to wear away. So I believe my best option is to take a heat gun, remove all the current sealer and then re-seal the gap with something new.
My question for the community is if it is better to seal the gap with actual cement or with more of a sealer type product? The criteria for "better" is longevity and not letting water in the gap. I do live in a state that gets a decent amount of snow so there is expansion / contraction to worry about. If the choice is a sealer type product, which material choice will hold up the longest? I am not looking for product recommendations, I am looking for material recommendations.
