At an installed cost of about $7,000, itâs an appliance that makes very little financial sense for most people. Tesla lists the price of the battery at $3,500, but that does not include installation, or an additional piece of equipment called an inverter that is needed to connect the battery to the home.
Strong blacktop driveways are typically built using crushed angular gravel as a base. This gravel needs to be a minimum of 6 inches thick for light vehicle traffic such as cars. If you expect larger commercial trucks on your driveway, I would install a gravel base that is a minimum of 8 inches thick. The soil beneath the gravel must also be of good quality.
The main priority in having a properly built driveway is the concrete thickness. You will want to consider the type of vehicles you will be parking upon that drive before you decide the thickness. If you will be parking normal cars, you can go with a four inch concrete thickness. If you have plans to park a heavy truck, camper, or a boat on your driveway, it is recommended to pour a five inch thick driveway.
