Hello Experts,
Need your advice here… I have grass growing on footpath gap between concrete and my driveway. I did applied weed killer multiple times but it keeps re-growing after some time. Could you please provide solution to fix this permanently. I thought of removing and cleaning that block and put quickset cement but then my neighbour said it may give cracks to your driveway as there is purpose of that gap so that driveway can contract during different wethers. My driveway is 4 years old already so not sure if that implies to my driveway.
Thank for reading long post.. awaiting for valuable suggestions.
