Get matched with top paving pros in Wright, WY

You should place a layer of thick landscaping fabric directly over the concrete slab and then a thin layer of leveling sand over that to protect the pavers from moisture. For border pavers, you should plan on locking them in place with polyurethane adhesive. This will prevent them from shifting under foot traffic.

Yes, it is possible to pave over an existing driveway, but whether it's the right choice depends on several factors. If the underlying structure of your current driveway is still strong, concrete or asphalt resurfacing can be a cost-effective way to prolong its life. However, if your driveway has significant issues like potholes, deep cracks, or other inconsistencies, it is best to remove the old driveway and start from scratch. Key factors to consider include the current driveway's condition, the compatibility of the new material, the added thickness and height, and the necessary surface preparation.

You can pour concrete over asphalt if it’s in good condition, thick, stable, and well-compacted. Concrete is more durable than asphalt and can extend the lifetime of your driveway without having to pay frequent asphalt driveway repair costs or replace it completely. 

But this is best reserved as a temporary solution based on budget restraints, as asphalt requires more frequent repairs and assessments than concrete. Once that concrete top is poured, it’ll be harder to accurately understand what’s happening beneath that layer, which could lead to more issues.

The average cost of 1,500 square feet of asphalt ranges from about $10,500 to $22,500, depending on location, thickness, base material, and how accessible the job site is to crews and equipment. Keep in mind that your asphalt material cost may vary depending on its type, ranging from porous asphalt to heated blacktop. Standard asphalt costs $7 to $13 per square foot.
