A concrete driveway should stay strong and visually appealing for years. When cracks or sinking occur, the cause is usually poor preparation, incorrect thickness, or inadequate curing. Focusing on these fundamentals is key to achieving a durable result.

Take time for proper preparation

A solid foundation is essential. To ensure your driveway will last as long as you want it to last you must take proper preparations and considerations before you touch any concrete. Remove all topsoil until firm ground is reached, then install a 100–150 mm sub-base using well-graded aggregate. Lay and compact it in layers to prevent future movement.

Drainage is equally important. Create a gentle fall so water runs away from the surface instead of pooling. You also have to consider the weather conditions when you are pouring the concrete. If it is going to rain how will you protect the area and keep it dry to keep the compound consistent throughout as that could weaken the concrete and cause you potential issues later down the line.

Slab thickness & strength

The thickness of the concrete determines how well it handles weight. For most domestic driveways, 100–125 mm is suitable for cars, while 125–150 mm is better for heavier vehicles like vans. Areas under higher stress, such as entrances, should always use the thicker option.

For the strongest and long-lasting driveways a C25 to C30 concrete mix is typically used, providing the strength needed for regular use and changing weather conditions. Concrete naturally cracks as it cures, but reinforcement helps control and minimise this. Steel mesh is the most common option and should be placed in the middle of the slab using supports, not directly on the sub-base.
