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.
Iâd like an answer from someone with experience in these things. Four inch thick concrete is fine for most walk ways and driveways. If the sidewalk is crossing a gravel drive it will be subjected to uneven forces not encountered in a fully paved drive. Be sure the base soil and gravel are tamped down and very firm.
