Hi there, I am looking to repair cracks that have started to appear in my driveway, see images. What would be the best way to repair these? Also what options do I have for trying to match the colour or something that will blend in.
Welcome to the Bunnings Workshop community @BenS1701. It's wonderful to have you join us, and many thanks for your question about filling gaps in concrete.
You'll need to use a flexible sealant to fill these cracks. I suggest you look at Selley's No More Gaps in the colour sandstone. Poly Gap Filler in cedar and vanilla might also come close. Obviously, you'll need two different colours, one for the blocks and one for the grout lines. It will take some patience, but if you get two close colours and stop and start the different colours to match the pattern, it should blend reasonably well. It's certainly better than just using one solid colour for the cracks.
