How to fill a wide gap between garage floor and driveway
Standard tube caulk is too narrow for gaps several inches wide, leaving spaces that fill with debris, grow weeds, and risk water erosion at the base. Finding a durable, cost-effective way to cap or fill this space is necessary to prevent structural damage without resorting to methods that quickly fail.
