Concrete Leveling questions, answered by experts

Pervious concrete should be between 4 and 8 inches thick to drain water properly. Surfaces like parking lots and driveways should be at least 6 inches thick to accommodate the weight of vehicles, while patios and walkways may be poured between 4 and 6 inches thick. There’s no standard for pervious concrete thickness, but in most cases, the more weight the surface will need to hold, the thicker it should be.

Asphalt and concrete have their pros and cons, but it really depends on your priorities. If you’re looking for durability, concrete’s your best bet, lasting up to 50 years with minimal upkeep. Asphalt, on the other hand, needs more TLC with regular resealing but is cheaper to install and easier to repair. Concrete also wins in curb appeal and resale value, offering homeowners more customization. But if you’re looking for quicker, more affordable installation, asphalt has the advantage. Ultimately, your decision should align with your budget, willingness for maintenance, and design preferences.

Tree roots don’t necessarily break through concrete on their own, but they can certainly take advantage of existing cracks, even very small ones. As roots grow, they expand the cracks, making them larger and leading to serious and costly foundation damage. It’s a good idea to have repairs on any foundation cracks you’re concerned about.

Yes, spraying water on the surface helps concrete cure evenly by preventing the top layer from curing long before the wet bottom layer cures. Otherwise, the top layer will cure and shrink, creating tension, and this tension will tear the top and bottom layers apart, creating a weakened slab. Water prevents this from occurring.

Yes, you can pour concrete over an existing concrete basement floor to save time and money on fully ripping out an existing concrete slab. However, it’s not a perfect solution, so consult a pro before moving forward. You must take specific measurements, and these kinds of floors don’t have the same longevity.
