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.
In order for your concrete driveway to last for years and years, the first steps in preparing the subgrade are critical. Your subgrade should be evenly compacted. A standard driveway is 4â thick of concrete. It should be 4â thick throughout and should not vary 3-4â. 1â deep joint should be created in the concrete in a 4â thick driveway. There is also proper spacing that should be followed for the joint placement. On a 4â thick driveway, joints should be spaced no farther than 8â-12â apart.
